QR Codes
Think we’re going to see a lot more of these. QR code’s or two-dimensional barcodes can contain URL’s as well as other information (text, music, voice, logos) and can be scanned using mobile devices with appropriate reader software. Easy to generate and pretty much used for everything in Japan, expect to see these being used widely in marketing and advertising over here. There’s more over at Kaywa and 2D Code.
