Barcodes 2.0 - No not QR codes - Bokodes just 3mm across these can hold thousands of times more information than barcodes and can be read by a standard mobile phone camera.
The BBC reports today on Bokodes, a new 'barcode'. MITMedia Lab plan to unveil what is described as 'an LED, covered with a tiny mask and a lens' at the Siggraph, conference next week.
The BBC quotes Dr Ankit Mohan, author of this paper and one of the MIT team, "Let's say you're standing in a library with 20 shelves in front of you and thousands of books.""You could take a picture and you'd immediately know where the book you're looking for is."
Bokodes can be read from a distance of up to 4m (12ft), or potentially as much as 20m (60ft). They cost about £3 each to produce - but could these eventually challenge RFID as the ID of choice for libraires in the future? RFID is widely adopted now but there is vulnerability with tag collision and interference and of course RFID provides little information for the customer unless they have a specialist RFID reader, Bokodes could provide much more utility and information for any user with a mobile phone camera.
