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.

QR code seems better than the conventional bar codes, for that matter. It would require new or updated hardware but seems to me a  much better option.

Tell me more about these so-called "3D barcodes".  QR codes are 2D, but you want barcodes that pop out of the paper?  Explain.

well QR code or whatever.

the main point is to get rid of friggin' metal coins that way. QR code would be fine
