Alternative To QR Code Uses NFC and Cheap Rectennas
An anonymous reader writes "The BBC reports researchers in Korea have developed a technology that can be used as a viable alternative to QR codes. Made of plastic and electronic ink, the rectennas cost less than one penny each to produce and use the NFC standards for wireless radio communication to devices. They are seen as a cheap, easy-to-print and environmentally friendly way to overcome the limitations and inconvenience of QR codes, the usage of which has greatly increased in the last few years."
Rectannas is just not an appealing word...
The entire point of a QR-Code is that it can be placed where-ever anything visual can be placed. You can put a QR code on a billboard, on a streetsign, on a television image, in a newspaper, on a bus ad...
You are not alone. This is not normal. None of this is normal.
They are seen as a ... environmentally friendly way to overcome the limitations and inconvenience of QR codes...
I'm mystified how that works. Its not like QR codes are inherently toxic by shape, like prions, nanoparticles, or asbestos fibers.
The only QR code I've ever used for a "real" purpose is holding my phone up to the screen to scan a google authenticator QR code. I'm not sure how that would translate to a NFC solution like this... have to print out on a 3-d printer or something?

limitations and inconvenience of QR codes
Which are what exactly?
The only limit I can imagine is the amount of data. Since they typically only store a URL, this is hardly an issue.
And how does this "Rectenna" relate to RFID?
Slashdot social media options: AIM, ICQ, Yahoo, Jabber and Mobile Text. Why no MySpace?
No kidding. The summary quoted(?) this nugget: "...to overcome the limitations and inconvenience of QR codes, whose usage has greatly increased in the last few years."
I'd say that the reason usage QR codes has greatly increased in the last few years is because they are not so limited or inconvenient as the article asserts. The QR code may contain several types of information, but in a 2D bit array, you are inherently limited. QR codes are not a high-bandwidth transport, but even if all they contain is a vcard or URL, the URL is the gateway to larger content.
I like QR codes because they are inherently opt-in. Screw the NFC based ad network!
So... reading up on this stuff... it's *very* clear that what they are talking about is an RFID tag.
Yay, put rfid tags everywhere and have everyone tap their phones against them to "receive information". ...and who determines what information is transferred back and forth and what types of exploitable holes are there in their protocol?
WAIT wait wait. What the researcheres in Korea "discovered" is how to PRINT rfid tags with magnetic inks.
Jeezus, this is what you get when you cross marketing droids with non-technical reporters in news organizations.
This whole slashdot article should be deleted. And the BBC should be ashamed, aren't there some PhDs driving cabs that they could hire to cover their technology news stories?
You're using a poor scanner then, or a crap phone (that wouldn't have NFC anyways).
My phone takes maybe half a second to scan a QR code, to the point that I don't even have to actually hold it still... I can *nearly* just wave it in front of the code and have it work, I do have to pause for the half second. By far the limiting time factor is finding the icon and launching the scanner, which would not change with NFC.
He's implying that if apple thought it could make a buck off of it, they'd take the option to turn it off out.
