How strange, this was just discussed over on Reddit! A user posted about their library having new vending machines, people were discussing QR codes for nutrition and stuff, I suggested QR codes for liking remotely. It's an excellent idea and will probably happen with the rise in smart phones, maybe blippy are in a position to do this, maybe they're already developing it!
