How RFID tags became trendy
As far as wireless technologies go, radio-frequency identification (RFID) is one of the oldest. Patented in 1983 by the late British inventor Charles Walton, RFID made it possible for new, cutting-edge tech such as near-field communication (NFC) to exist. As with NFC, RFID chips are used to store information digitally, which can then be shared between objects through electromagnetic fields and radio waves. It may not be sexy, but companies see real potential in the technology, no matter how old. It's no surprise, then, that over the past few years RFIDs have become ubiquitous in a wide range of industries, including travel, sports and one you wouldn't expect: fashion.
Nanotubes sniff out rotting fruit, your dorm room might be next
Our favorite ultra-skinny molecules have performed a lot of useful functions over the years, but keeping fruit flies away was never one of them. Now MIT scientists, with US Army funding, have discovered a way to give these nanotubes the canine-like sense of smell needed to stop produce spoilage and waste. Doping sheets of them with copper and polystyrene introduces a speed-trap for electrons, slowing them and allowing the detection of ethylene gas vented during ripening. A sensor produced from such a substance could be combined with an RFID chip, giving grocers a cheaper way to monitor freshness and discount produce before it's too late. If that works, the team may target mold and bacteria detection next, giving you scientific proof that your roommate needs to wash his socks.
Doh uses RFID and Arduino to help you remember your wallet, continues search for the 'Any Key'
If you can dream it, Arduino can help you build it -- perhaps with a dash of MakerBot thrown in for good measure. The latest homebrew project to hit the ol' inbox sounds an alarm whenever you leave a room without a registered item. Doh (named in Homer Simpson's honor, we presume), uses a trio of devices to track items that you usually travel with, like your keys or a cellphone. After you've assembled the rather complex contraption, you affix color-coded RFID tags to your gadgets, before registering them with the Arduino-based host. If you leave the room without all of the items that you've registered as a "grouping," a door handle-mounted display will indicate what's missing by flashing its color and sounding an alarm. If you've forgotten multiple items, the display will cycle through the associated colors. There's also a two-way "buzzing tag" that beeps until it's found, if you wish to add that to your collection. It's not a turnkey solution by any means, but unlike Homer, at least you're not being tasked with preventing nuclear meltdown. And if you're looking for a time-proven alternative, a pen and a pad of stickies should do. Jump past the break for a demo video, banjo-equipped soundtrack and all.
Viatag NFC system pays parking lot fees with an RFID tag, saves lives
Paying for parking isn't exactly a fun experience, but Germany's Fraunhofer Institute is doing its best to make it slightly less painful, with Viatag -- an NFC system that allows you shell out your hard earned cash without even reaching for your wallet. The setup is relatively simple, consisting of a small RFID tag, compatible transceivers and a centralized database. Once attached to your car's windshield, the tag communicates with the transceivers installed within a given parking lot, alerting the system whenever your vehicle enters or leaves. An application running on the central server, meanwhile, keeps track of how much time you spend in the lot, and charges your debit card accordingly. Researchers have already installed Viatag at car parks in Essen, Duisburg and Munich, and are hoping to expand it to other locations. It might not be as sophisticated as some of the other automotive communications systems we've seen, but it could come in handy during those moments when you really don't feel like swearing at a parking meter.

RFID tags let you share waterpark photos on Facebook without leaving the lazy river
See this happy couple? They're smiling because they're in love, they're at a waterpark, and they haven't contracted E. coli yet. They could also be chuckling with the knowledge that all 700 of their closest Facebook friends will soon see them canoodling in an artificial lagoon, thanks to a strange new photo-sharing program from Great Wolf Resorts. From now on, visitors to Great Wolf's Grand Mound lodge will be able to automatically post their vacation pics on Facebook, using only an RFID-equipped wristband. All they have to do is register their accounts at check-in, slap on their bands and head over to any of five kiosks stationed throughout the resort, where they can pose for pictures that will be instantly uploaded to their walls (along with captions). Immediately de-tagging yourself, however, remains a uniquely manual task. Wade past the break for the full PR.
NutriSmart prototype embeds RFID tags directly within food, traces your lunch from start to finish (video)
RFID tags are already used to trace everything from poker chips to hotel towels, but what if these little pellets were embedded directly within your lunch, providing everything you'd ever wanna know about that ham sandwich you're about to beast? That's the idea behind NutriSmart -- a food tracking system that revolves around edible RFID tags. Developed by Hannes Harms, a design engineering student at the Royal College of Art in London, these little markers would allow consumers to trace the entire supply chain behind every item in their cupboard, while feeding valuable nutritional information to dieters or people with particularly dangerous food allergies. Kodak, as you may recall, came up with a similar idea a few years ago, though Harms' prototype extends beyond the realm of medical monitoring. Properly equipped refrigerators, for example, would be able to alert users whenever their stock's about to expire, simply by scanning the tags. The NutriSmart concept also calls for a smart plate, which Harms describes as an "invisible diet management system." Just put your meal on the plate and an embedded reader will analyze your grub, tell you how many miles it traveled before arriving at your kitchen and transmit all of its history and caloric data to your phone, via Bluetooth. No word yet on what would happen to these tags post-digestion, though our inner 13-year-olds are giggling at the possibilities. Video after the break.
IDEO constructs RFID turntable, hearkens back to mixtapes of yore (video)
Once upon a time, you could touch your music -- or at least caress a 7- or 12-inch vinyl disc -- but these days the cool kids stream MP3s (and OGGs, and APEs) off the internet. However, design studio IDEO recently decided to see if they could get back in touch with their audio roots, and -- taking a page right out of the industrial design treatise I Miss My Pencil -- they built the above machine. To put it simply, what you're looking at is a box filled with specially-angled Arduino Pro Mini boards constantly searching for RFID tags on top, and a set of cards each with two RFID tags, with each tag representing one song. When you drop one on the turntable, it begins playing within a second, thanks to the clever array of Arduinos underneath, and you and your High Fidelity soulmate can leave multiple cards on the table to create an impromptu mixtape, or, presumably, flip one of the "cassettes" to play Side B. It's a good thing IDEO isn't selling the device and packs of cards, because we're afraid we'd be compelled to collect them all, and our poor wallet doesn't need any more heartbreak.

Rfiddler zapper kills RFID tags dead, the hard way
Sure, there may be a number of relatively easy ways to destroy or disable an RFID tag (tossing it in the microwave, for instance), but where's the fun in that? There are plenty of good times to be had with this so-called "Rfiddler" built by Codeninja though, which disables tags (and potentially anything else in its sights) by emitting a strong electromagnetic field -- not to mention some sounds that will cause anyone standing in its vicinity to take a few big steps back. Head on past the break for a video, and hit up the link below for the complete parts list if you're interested in building your own.
Tikitag renamed Touchatag, adds QR codes to repertoire
We haven't heard much from Tikitag since they showed up on the scene last September, sticking RFID tags to everything in sight. The Alcatel-Lucent Venture-backed company's popped up on the radar again, only this time it's taken on a more tactile-focused name, Touchatag, and is now touting 2D barcode support, including do-it-yourself tag creation system for adding some QR ciphers to your business cards or anything else you wish to lay claim. No word on the new pricing -- a Tikitag RFID set was supposed to cost $50 in October -- but if you're interested in testing the service out, there's a sign up to join the developer community on their main site.Read - Press ReleaseRead - Touchatag Developer Network
Verayo's "unclonable" RFID uses physical characteristics to thwart hackers
This era of RFIDs everywhere means a new era of hacking, one where a reader and a copy of RFDump are just as important as a proxied Internet connection and a telnet client were in the past. As MythBusters attempted to show, existing RFID chips and tags seem universally hackable and clonable, whether they be inside your passport or inside of you, but a new one from Verayo is said to be totally impenetrable -- for reals this time. It uses Physical Unclonable Functions, or PUF, a randomized coating of wires that both protect the internals from interlopers and also return a (supposedly) unique identifier that (supposedly) can't be duped. Truth in advertising? Hackers worldwide are itching to find out after the thing's formal introduction tomorrow morning at the RFID World conference -- surely the hottest ticket in Vegas this week.

Tikitag promises to bring RFID tags to everything
The Alcatel-Lucent-backed Tikitag sure has managed to keep a low profile until now, but it looks to have made quite a splash at the DemoFall conference this week, where it showed off its RFID tagging system that's apparently set to go into public beta in less than a month. The system, which Tikitag confidently boasts will "build the internet of things," promises to let you add an RFID tag to anything you like and associate it with a webpage or application -- for instance, a business card that links to page with all your social networking information or, less usefully, a cube that you can use to control iTunes. Intrigued? You'll apparently be able to pick up the Tikitag reader and ten tikitags for $50 on October 1st, with boxes of 25 tikitags also available for those looking to get a little more ambitious.[Via CNET Webware]
VeriChip wants to chip every US soldier
Despite some pretty significant security concerns, everyone's favorite futurific company VeriChip is looking to get its chips under the skin of the largest group of people yet: the entire US military. According to the DC Examiner, the company is lobbying the Pentagon to choose its RFID tags as a replacement for the famous metal dog tags, making information like a person's name and complete medical record instantly available with the swipe of an RFID reader. Needless to say, not everyone's sold on the idea, with veterans' groups and some members of Congress already raising concerns. There doesn't seem to be any indication as to when a decision might be made, although given VeriChip's political connections, we wouldn't be so quick to bet against it.[Via Newsmax]
