Some years back proximity marketing via Bluetooth was a big thing and we were lucky to be involved with couple of projects making it possible but then the Bluetooth virus came to light and people stopped leaving their Bluetooth on in public places. Doesnt look like Bluetooth based proximity marketing has gone very far since those days.
QR codes is a simple way to for advertisers redirect the end users to their websites but then recently I read that a rogue QR code can be used to redirect the end users to a site that can be used to hack their phones. The main thing pointed out is that 99% of the time QR codes are read by mobile phones and 99% of these phones are either iPhones or Android's, which can help narrow down the exploits.
There is a good chance that when there is mass adoption of these new technologies, Security is going to be a big issue. Not sure if enough is being done. If there are any pointers on security issues please feel free to comment.

The Bluetooth Special Interest Group has said that the new version, Bluetooth 4.0, could be launching in the 4th quarter of this year with devices such as headsets, phones and PC’s all getting the technology.
The latest specification allows devices with smaller batteries to utilise Bluetooth. Previous versions of BT required that a device had at lease a AAA or larger capacity battery to function. The new 4.0 specifications allow for smaller devices that require coin-cell batteries to run.
As well as utilising less power, the device also has higher speed data transfer. Version 3.0 was launched last year although it kind of fell flat on it’s face due to the power requirements needed. Version 4.0 fixes those problems.
The new specification will carry the high-speed Wi-Fi feature introduced with Bluetooth 3.0. That allows devices to jump onto Wi-Fi 802.11 networks, where it can transfer data at up to 25Mbits per second.
Hopefully with the lower power requirements and the options to switch to 802.11 networks we should start seeing more devices using the Bluetooth specification.

Three prototype solutions for preventing mobile phone theft have been unveiled.
The i-migo, the 'tie' solution and TouchSafe have been developed to counter crimes such as mobile phone identity fraud, which rose by over 70 per cent in 2009.
TouchSafe uses Near Field Communications (NFC) technology similar to that used by the Oyster Card and requires the handset's owner to carry a small card with them that they touch on the phone every time they make a purchase.
The 'tie' solution makes an association between a handset and theSIM chip so that other SIMs cannot be used on the handset should the mobile phone be stolen.
And the i-migo is a small device carried by the mobile phone's owner that sounds an alert and locks the handset should it be taken outside of a set range. Additionally, it automates the back-up of any data stored on the device.
The prototypes were inspired by a Home Office initiative to develop new ways of preventing mobile phone theft and will be shown off atMobile World Congress in Barcelona next week.
Home Office Minister Alan Campbell said: "As new technology creates new opportunities for the user it can also provide criminals with opportunities as well.
"I believe the solutions developed by this challenge have the potential to be as successful as previous innovations like Chip and Pin, which reduced fraud on lost or stolen cards to an all-time low, and would encourage industry to continue working with us and take them up," Campbell continued.

Remember Bluetooth 3.0? Its been a while and the world has changed in the mean time.
Samsung S8500 will launch next-generation Bluetooth 3.0, a protocol that will establish transfer speeds up to eight times faster than 2.0… 24mbps!
Samsung have not been officially announced yet to carry the Bluetooth 3.0 on the S8500 but the device has been leaked to carry 3.0 Bluetooth connectivity that will dwarf previous 3mbps speeds.
The listing from the Bluetooth Special Interest Group it is slim, compact, will come in several colours, and also contains quad-band GSM/EDGE radios. Other details are scarce, and it’s likely that the spec may change considerably before we get our hands on the actual handset
Broadcom is also focusing on Bluetooth 3.0, which allows Bluetooth-centric designers to use the 802.11 physical layer to provide Wi-Fi-speed data transfers in a Bluetooth environment. Bluetooth 3.0 supports bulk synchronization of music libraries between PCs and music players or phones, supports wireless transfer of photos to printers, and sends video files from cameras or phones to computers or televisions. An alternative for Wi-Fi-centric designers, says Ochikubo, is Wi-Fi Direct, which enables Wi-Fi devices to connect and share data without joining a traditional home, office, or hot-spot network. Whatever approach Broadcom’s customers choose to take, he says, he sees Broadcom’s recently announced InConcert Maestro software platform as making the operation simple and transparent for the end user.
In addition to focusing on the higher speeds that Bluetooth 3.0’s Wi-Fi physical layer affords, the Bluetooth Special Interest Group is also focusing on low-power applications with its “Bluetooth low-energy,” or Bluetooth 4.0, specification. Bluetooth low energy will address markets such as health care, sports and fitness, security, and home entertainment.

Microdisplay technology maker Kopin Corp. reports it has partnered with Motorola Inc. to introduce a wireless headset with a high-definition virtual display and speech recognition for remote control of things such as smart phones and PCs.
Taunton-based Kopin (Nasdaq: KOPN) teamed up with Motorola’s Enterprise Mobility Solutions division to put a 15-inch virtual PC display together with a microphone and earpiece into the headset it calls the “Golden-i.”
According to material from Kopin, the Golden-i uses Bluetooth 2.0 to connect to the devices, as well as to Bluetooth-enabled peripherals such as a mouse, touchscreen or keyboard. Golden-i runs on the Microsoft Windows Embedded CE 6.0 R2 operating system, and once connected, users will see their PC desktop screen on the 15-inch virtual display.
To control the connected device hands-free, Kopin is incorporating the VoCon3200 software from Burlington-based Nuance Communications Inc. Golden-i also uses Nuance’s text-to-speech application to read back documents, e-mail messages, web content or any text on the display screen. According to Kopin officials, it supports up to 20 languages.
If no interface peripheral such as a Bluetooth mouse is available, Golden-i can use its built-in Hillcrest Labs 6-axis, real-time position tracker to allow control of the connected device using head gestures. The device also provides a mini-USB port, and a removable Micro SD card slot taht can support up to 32GB of memory.
The target market for Golden-i, according to Kopin, is remote workers looking to quickly connect to a PC or network for information, such as outside sales staff. It is also aimed at network support personnel, as it can support connections to multiple devices, Kopin said.Kopin, which counts the defense industry as a major customer, last December reported it had landed $3.1 million from the U.S. military for displays used in weapon sights.
Once connected to a host device, such as a PC, users see their PC desktop screen on the 15-inch virtual display and with Nuance’s VoCon3200 software they can control it using voice commands in a number of languages. Kopin claims this software provides more than 90 percent proficiency straight out of the box, and the more it is used, the better it works.
Golden-i requires no push-to-talk buttons and is ready to respond to a user’s request whether in light hibernation or during intermittent use. Golden-i also readily accepts conventional user interface from any host device touch screen, keyboard or wireless mouse and integrates Nuance text-to-speech, enabling Golden-i to read back any text displayed in a number of common languages.
Running on the Windows Embedded CE 6.0 R2 platform, Golden-i can remotely wake a PC from practically any location and, when work is finished, the PC can be placed in hibernation with a single spoken command. The headset can also remotely control up to seven other devices or networks at one time, similar to the way users control software applications on a PC desktop.
It operates much like a highly mobile server, a hub between various host devices. If a USB interface or removable memory is required, Golden-i provides a mini-USB port and a removable Micro SD card slot capable of supporting up to 32GB. Supported by Texas Instruments’ third generation OMAP dual processor platform, a single 1200 mA/hr li-ion battery should provide more than eight hours of standard use.
While the Golden-i can be used just about anywhere, it is designed for “mobile information snacking”, rather than continuous use over long periods. Initial development of the unit has focused on industrial applications, so Kopin is seeking to engage several industrial organizations in several months of in-depth field testing and evaluation. Kopin hopes to incorporate any improvements and refinements uncovered during testing into its Golden-i products, which are expected to be available in 2010.
Kopin believes Golden-i will free users from the need to carry a PC or laptop about with them. Freedom from work, though, is another matter entirely.

Derek Soh is the Bluetooth SIG’s marketing director for APAC and Japan. He agrees with Naudo’s assessment, noting a Millward Brown study that showed only 60 percent of the Japanese population is aware of the technology, versus up to 85 percent elsewhere. This is puzzling, given that Japan has so many companies developing and pushing the technology. According to Soh, among companies represented in the Bluetooth SIG, Japan has the third-highest number of Bluetooth SIG Associate members after the United States and Taiwan, and it boasts the fourth-highest number of Adopter members.
In Europe and the United States, concerns about the health effects of cellphone usage and laws against using mobile handsets while driving fueled the proliferation of wireless headsets. However,in Japan people tend to spend less time driving and more time taking public transit. There is also a cultural preference for mobile text messaging over making voice calls. While the Japanese government enacted stiffer penalties in 2004 for driving while talking on a cell phone, the uptick in Bluetooth enabled headset sales has been modest. “Headsets just don’t appear to be available in as many retail outlets as in other countries,” says Green.
But there is light on the horizon. “The number of Bluetooth enabled handsets in Japan is forecast to grow from just under 20 million—30 to 40 percent of those shipped—in 2007 to over 60 million, 80 percent, in 2013, a CAGR (compound annual growth rate) of 24 percent,” says Naudo.
In addition to more headset use, there are other reasons for the optimistic forecast. “Streaming music services over mobile networks, such as Japan’s Chaku Uta, will be key drivers of Bluetooth inclusion in cellular handsets,” predicts Andy Bae, a senior analyst at New York-based ABI Research.
Bluetooth technology is making inroads in several other Japanese sectors as well. The auto industry is installing the wireless specification in more and more new cars. “Japanese automakers have lagged behind their European and U.S. counterparts in adopting Bluetooth technology, but now they are beginning to catchup,” noted an article in The Nikkei Weekly, a business newspaper published in Tokyo.
Says Green at IMS Research, “We estimate that around 24 million Bluetooth chips were used by automotive companies in 2007,” although he added that “only around 10 percent of cars produced in 2007 had Bluetooth technology built in at the point of production.” That has opened up a new market for after market products like hands-free kits, navigation devices and A/V systems.
Another sector where Bluetooth technology may see further success in Japan is video games. “In 2007, total shipment volume of Bluetooth enabled gaming devices such as the Nintendo Wii and Sony PS3 surpassed that of Bluetooth enabled headsets – amazing!” says Soh.
Finally, several companies, including Toshiba, will begin rolling out Bluetooth low energy enabled devices aspart of a personal health care ecosystem by mid-2009, and many hope this effort will help familiarize Japanese consumers with the technology. (Click here for more on Toshiba and the Japanese health care market.)
With the ongoing updates to the Bluetooth core specification, developers are planning plenty of newproducts featuring the technology. Whether Japanese consumers will bite remains to be seen.

From its annual All Hands Meeting in Tokyo this week, the Bluetooth SIG formally adopted Bluetooth Core Specification Version 3.0 High Speed (HS), or Bluetooth 3.0. This latest iteration of the popular short-range wireless technology fulfills the consumers’ need for speed while providing the same wireless Bluetooth experience – faster. Manufacturers of consumer electronics and home entertainment devices can now build their products to send large amounts of video, music and photos between devices wirelessly at speeds consumers expect.
Bluetooth 3.0 gets its speed from the 802.11 radio protocol. The inclusion of the 802.11 Protocol Adaptation Layer (PAL) provides increased throughput of data transfers at the approximate rate of 24 Mbps. In addition, mobile devices including Bluetooth 3.0 will realize increased power savings due to enhanced power control built in.
On March 16, 2009, the WiMedia Alliance announced it is it will transfer all current and future specifications to Bluetooth, and the Wireless USB Forums. After completion of the technology transfer, the WiMedia Alliance will cease operations.
More than eight new Bluetooth enabled products are qualified every working day and more than 19 million Bluetooth units are shipping per week, says the Bluetooth SIG, with over two billion Bluetooth devices in the marketplace.
The Bluetooth SIG includes Promoter group companies Ericsson, Intel, Lenovo, Microsoft, Motorola, Nokia and Toshiba, along with over 11,000 Associate and Adopter member companies. The Bluetooth SIG, Inc. headquarters are located in Bellevue, Washington.
The next-generation Bluetooth is said to operate at similar distances (around 30 feet, best case) to today’s Bluetooth 2.0 but is a lot faster, capable of wireless transfers at a rate of 480Mbps. That’s the amazing 60MB per second, fast enough for high definition videoconferencing or moving files around at a fairly rapid clip.
That kind of speed blows the doors off Bluetooth 2.0, which pokes along at a mere 2.1 Mbps. The new Bluetooth gets its exponentially faster speed by teaming up with ultra wideband technology (UWB). But there are other contenders using similar tech such as Wireless USB (also 480Mbps), and it’s hard to tell how these various protocols will compete with each other, but for sure it is gonna be good for the consumers like us.
With the availability of Bluetooth version 3.0 HS, consumers can expect to move large data files of videos, music and photos between their own devices and the trusted devices of others, without the need for cables and wires. Some applications consumers will experience include:
- Wirelessly bulk synchronize music libraries between PC and music player or phone
- Bulk download photos to a printer or PC
- Send video files from camera or phone to computer or television

The Bluetooth SIG global headquarters are in Bellevue, Washington, USA and has local offices in Hong Kong, Beijing, China, Seoul, Korea, Minato-Ku, Tokyo, Taiwan and Malmo, Sweden
During the presentation in the conference there were discussions on technical and general stuff about short range wireless and hence I learned some amazing things especially about Bluetooth technology and its application in our daily life. Although my expertise and main focus lies in the area of 3GPP technology i.e. HSPA+, LTE etc I occasionally do pay an interest in Bluetooth and other W-Fi technologies. After attending the SIG conference I do know now that there are some amazing things that can be done with Bluetooth other than just using it as a Hands free kit while talking on you mobile. There are already around 2 billion Bluetooth enabled devices in various forms in the market place.
In terms of business there is also an enormous scope to develop customized applications that can work with Bluetooth and UWB (ultra-wide band, ultraband, etc.).
UWB is advanced form of Bluetooth where the MAC/PHY layer is changed to accommodate high data rates.
UWB is a radio technology that can be used at very low energy levels for short-range high-bandwidth communications by using a large portion of the radio spectrum thus enabling higher data rates. UWB communications transmit in a way that doesn't interfere largely with other more traditional 'narrow band' and continuous carrier wave uses in the same frequency band. IEEE 802.15.4a in its draft standard and working group has proposed UWB as an alternative PHY layer.
Low energy Bluetooth is another emerging flavour which will be talked very often in the coming days. Bluetooth low energy is the next generation of wireless standard from the Bluetooth Special Interest Group (SIG) addressing a completely new set of applications but building on the installed base of Bluetooth devices. As the name implies devices based on Bluetooth low energy consumes only a fraction of the power of the classic Bluetooth radio thus allowing small and low cost implementations.
Bluetooth low energy technology is designed with two equally important implementation options:
- Single-mode (stand-alone) implementation: Targeted at applications requiring low power consumption and small size; typically button cell battery -powered devices, for e.g. sports & fitness equipment and sensor devices
- Dual-mode implementation - an extension to a classic Bluetooth radio: Targeted at mobile phones and PCs.
Bluetooth low energy is very robust through frequency hopping compared to other similar technologies. It is very secure through optional 128 bit AES encryption.
The significant factor of Bluetooth low energy is its low power consumption which is by very low standby activity, fast connection setup and low overhead in data packets.
Bluetooth low energy technology explores new market opportunities. It is sometimes unbelievable to see where and how Bluetooth low energy technology can be used. One of the most amazing uses of this technology which I came across was when I came to know that a double amputee can walk again using Bluetooth. Marine Lance Cpl. Joshua Bleill (USA Army) lost both his legs above the knees when a bomb exploded under his Humvee while on patrol in Iraq on October 15, 2006. He has 32 pins in his hip and a 6-inch screw holding his pelvis together.
Now, he's starting to walk again with the help of prosthetic legs outfitted with Bluetooth technology more commonly associated with hands-free cell phones.
Bluetooth is definitely evolving and low energy Bluetooth is very much part of its evolution. The technology has a major parto play in our daily lives and the currently the Sports and Health Care is the significant area where the major focus is lying.
Bluetooth Low energy has a major role to play in sports and fitness. I personally has experienced the use of the Bluetooth device when I visit to Gym. I have to put the device around my chest and the machine then displays my heart rate transmitted by the Bluetooth device. This is amazing as I can constantly monitor my heart rate and based on that I can vary the intensity of my workout.
Thus sports person has sensors i.e Bluetooth device located on the body, shoes, garments and other fitness gear measuring the exercise session such as duration, speed, distance, cadence, slope, location, heart rate, energy consumption etc. Together with this information, when using GPS location related information can be combined with the data. Thus using a Bluetooth device is like training with a virtual partner. The use of the application can motivate and give feedback to the user and remote users, e.g. coach, team mate or a virtual partner. They can access the data remotely and then make decisions based on it for example the exercise can be simulated on exercise bike or treadmill along with multimedia content.
Low energy Bluetooth device thus helps play a significant role in sports persons real time activity and training monitoring.
I have seen Golfers using Bluetooth devices to record their swing. Golfers can thus monitor the real time data and thus can improve their swing. Golf player’s motions are recorded with sensor devices and the data is uploaded to a host device. The recorded data or values are transmitted to web service where the athletes can be remotely monitored online or offline by coach, audience, etc.
Health care is another major area where low energy Bluetooth devices have a significant role to play. There is a potentially market of greater than US$1 Billion for wireless health monitoring products. Examples of currently available medical devices using “Classic” Bluetooth technology are:
- ECG Monitors
- Cardiac Defibrillators
- Blood Glucose Meters
- Insulin Pumps
- Pulse Oximeters
- Blood pressure Monitors
- Weight Scales
Examples of healthcare devices suited to Bluetooth low energy technology, requiring very low power and long battery life are:
- Blood pressure monitor
- Weight Scale
- Heart Rate Monitor
- Blood Glucose Meter
Let’s consider the example of how the technology can help in the case of Diabetes management. The patient will be fitted with a small low energy Bluetooth device i.e. Blood Glucose meters typically powered by small coin batteries, operating for a year or more. Blood glucose measurement, data is automatically sent to the mobile phone and to the central Personal Health Record. Patient and care providers automatically alerted if the sugar level is outside preset limits and reminders and advice can be sent back to the patient and test compliance can be monitored.
Low energy Bluetooth devices can used in the consumer electrnics control as shownin the picture below.
I must say I was really impressed to finds out how the Bluetooth technology can be used in our daily life. Just by using a simple and small device many patients life can be saved as they are monitored constantly.

Bluetooth headset users are at risk because of a security hole in the technology and default PINs that don't get changed, he said. Exploiting vulnerabilities someone can break in and steal data from the phones, make calls without the cell phone owner knowing, listen in on and break into conversations, and even spy on people by turning the device into a bug. He advises that people change the default password, disable the Bluetooth on the phones, turn off the headsets when not in use, and limit access to the data and features when communicating with other Bluetooth devices.
There may be more reasons to switch Bluetooth off.
According to an article in Guardian:
Tens of thousands of Britons are being covertly tracked without their consent in a technology experiment which has installed scanners at secret locations in offices, campuses, streets and pubs to pinpoint people's whereabouts.
The scanners, the first 10 of which were installed in Bath three years ago, are capturing Bluetooth radio signals transmitted from devices such as mobile phones, laptops and digital cameras, and using the data to follow unwitting targets without their permission.
The data is being used in a project called Cityware to study how people move around cities. But pedestrians are not being told that the devices they carry around in their pockets and handbags could be providing a permanent record of their journeys, which is then stored on a central database.
The Bath University researchers behind the project claim their scanners do not have access to the identity of the people tracked.
Although initially confined to Bath, Cityware has spread across the planet after the software was made freely available on the internet sites Facebook and Second Life. Thousands of people downloaded the software to equip their home and office computers with Cityware scanners.
More than 1,000 scanners across the world at any time detect passing Bluetooth signals and send the data to Cityware's central database. Those with access to the database admit they do not know precisely how many scanners have been created, but there are known to be scanners in San Diego, Hong Kong, Australia, Singapore, Toronto and Berlin.
In Bath alone scanners are tracking as many as 3,000 Bluetooth devices every weekend. One recent study used the scanners to monitor the movements of 10,000 people in the city.
About 250,000 owners of Bluetooth devices, mostly mobile phones, have been spotted by Cityware scanners worldwide.
Bluetooth tracking technology is already being used to aim advertisements at people, for example as they walk past shops or billboards.
Bluetoothtracking.org, a website based in the Netherlands, is using the same technology to publish live data about people's movements across the town of Apeldoorn. The facility allows people to search the whereabouts of friends and associates without them knowing about it.
Some scientists using the technology describe a future scenario in which homes and cars adapt services to suit their owners, automatically dimming lights, preparing food and selecting preferred television channels.
I like Bluetooth as it makes my life convinient and also because one of our initial projects has been developing of complete Bluetooth marketing solution for a media company. So yes, maybe the next time you go to a shopping mall and get some advertised pumped on your handset using bluetooth then you can blame my company.
Ps: There is another article on Guardian by Dr Vassilis Kostakos from Bath University, defending his team. See here.

The popular wireless technology known as Bluetooth could get a lot faster next year by taking advantage of Wi-Fi technology already built into many gadgets.
Linking Bluetooth and Wi-Fi may make it easier and faster to transfer large amounts of music between computers and cell phones, or send pictures from a camera phone to a printer, or video from a camcorder to a TV.
Michael Foley, director of the Bluetooth Special Interest Group, said the first devices with the technology could be on the market in the middle of next year. The industry group behind Bluetooth, which has more than 10,000 member companies, plans to announce Monday that it is pursuing the technology and will make it available next year.
A fast transfer channel for Bluetooth using a different radio technology, ultra-wideband, was announced in 2006, but delays in getting it to work prompted the Bluetooth group to look at Wi-Fi too, Foley said.
Some products, like laptops, already combine Bluetooth and Wi-Fi functions, but they work off separate chips. Most likely, manufacturers will use single chips still under development that combine Bluetooth and Wi-Fi capabilities.
"It does appear that the first products ... are going to be Bluetooth-Wi-Fi, and our members want to take advantage of that," Foley said, adding that all the major makers of Bluetooth chips are participating in the project.
The combination devices will use the regular low-power Bluetooth radios to recognize each other and establish connections. If they need to transfer a large file, they will be able to turn on their Wi-Fi radios, then turn them off to save power after finishing the transfer, Foley said.
The new technology doesn't have a name, and it isn't clear how consumers will be able to tell it apart from Bluetooth-UWB devices, which the industry group still supports.
"This in no way ... changes our vision of using ultra-wideband technology for high speed when that technology is ready," Foley said.
While it started out as a specific radio technology, Bluetooth is turning into an umbrella standard for a variety of different radio technologies. Apart from the high-speed flavors, the SIG has incorporated an ultra-low-power wireless technology developed by Nokia Corp. and previously known as Wibree. Products like watches and pedometers that use that technology are also expected to hit the market next year.
You can also read the Interview of Bluetooth/WiFi Union here.
Personally I think when the UWB platform is fully available, it can support WiFi and Bluetooth 3.0 and then there would be some additional software upgrade for moving between them. Ofcourse the host and the controller both will have to support this new protocol.
