That's just it though, it is very limited and has issues with even simple text. Tryp said in this thread that they had to download additional stuff in order to display the text in a QR code.
I had similar issues when scanning a text QR Code. Being a QR code, it opened my browser... Simple text was displayed in my search bar in linear fashion. So basic formatting of text to make an ASCII bar graph, for example is not possible.
Without basic formatting capabilities it's almost useless for my purpose, unfortunately.
Absolutely. That's what I was getting at.
Being able to run down to my local postal Service and print out QR codes on stickers for next to nothing is much more realistic.
Whereas NFC or RFID would be more expensive, not as easy or convenient to replicate and the average person knows what to do when they see a QR code and that's not necessarily true of RFID or NFC.
