QR Codes, as a replacement for old bar codes, is a pretty awesome thing, and LiFi clearly wouldn't work for that.
LiFi sounds like a possible replacement for the (arguably) stupid usages of QR Codes, like, "point your phone here, and see what happens", although LiFi would be easier to embed in a hidden way.
On a monthly basis I see people come up with "innovative" shopping experiences. In fact I personally know 2-3 people who worked on projects like this, but did anyone actually figure out what content to put on the screen? Anyone here ever pointed a phone at a barcode/qr-code for any other reason but syncing up google authenticator?
But let's say we really would like to walk through macy's by staring at our phone instead of looking at the boots.
Why not just use something standard and readily available in every phone that matters, like NFC/BTLE?
I understand someone probably got the homework at Fujitsu Labs to innovate and I must admin I have worked on similiar technologies before and it's a lot of fun. But especially because I have seen this idea so many times, but never seen it adapted by a single store, I am skeptical about the existence of the problem.
URIBeacons are the future. You don't need to point a camera, it's invisible and works great.
Those can probably be solved by using a 3rd party service to resolve the URL redirection, but we'll see how it goes.
*Available right now
*Free to implement
I think it's actually a strength. You can probably train a monkey to scan a QR. Just point phone at funny square. With this, most people won't even know it's there, so you'll basically need to have your phone out (but you can't even use your phone while scanning for codes, like you can with bluetooth beacons).
This an impressive technology, but it's not going to "replace" QR, and the potential usage scenarios in the article are a little far fetched.
Honestly, I don't understand why we won't use them back here. If only just for scanning stock WiFi passwords off routers, surely that would be worth it?
Do you have any information about how widely adopted they are? I know they are very widely printed, I bought a USB battery pack and it's got a QR code printed on the end. But the interesting question is how often they are scanned.
The reason is that computer(connected to) cameras could read them much better than barcodes(which need lasers or high definition cameras). Camera sensors are so cheap now and they let you read 2D instead of 1D, so you could add much more info, with simple hardware(like not having to control the illumination environment so much).
I like the possibilities that come with Li-Fi, but it's a long ways from maturity.
That probably means you'll need to register your URL/vendor/etc. with Fujitsu, since sending a normal-sized URL would be excruciating.
"Here, just aim your smartphone at this for 10-20 seconds."
LiFi is still a neat idea though.
