Title: coinless shopping - print $ change on receipt as QR barcode Post by: mai77 on March 25, 2013, 03:35:00 PM If I was given the option of never having to carry metal coins with me any longer, I'd be glad to do that: ::) ;D
the shopping centres could offer to return the change instead of in metal coins in BTC bitcoin as barcode on the cashier receipt. :-* you could use your Android phone to process that fairly quick then. ;D most cash printers already print barcodes and such. or use a code scheme involving webpages and PINs. :D that would be a huge petrol saver too, considering the reduced weight in street traffic thereby.

It would require new or updated hardware but seems to me a much better option.
