Idea: NFC receipts as an alternative to paper receipts

I don't want to give you my email address, but you encode the receipt data onto an NFC pad I can tap my phone to, we can save paper without giving you that oh-so-tasty data

@sir Can also provide a QR code or similar for any devices that don't have an NFC chip.

@OTheB @sir A little screen displaying a qrcode but … will it have a smaller environmental impact ?

@lord @sir Why not use one of the existing screens? There's one pointing at the cashier, one on the card reader, self-checouts have huge screens. The possibilities are endless.

@OTheB @sir In my local shop there are screens in the self-checkouts but not the classic ones (execpt for the cashier).
