We've had a standard for this since 2013. Scan code, your bank app opens with the transfer as a template, you authorise it. Now, with SEPA instant transfers, it's guaranteed to arrive within ten seconds. No pointless third parties involved.
I see this being useful for non-permanent shops, like a strawberry farmer with their seasonal stand, flea markets, etc, but for permanent shops POS systems are superior, whether chip+pin, rfid with card, or rfid with phone. It's also useful for private-to-private transfers, my bank app can display the code, someone else can scan it, choose an amount, done. In the wild I've only seen them on paper invoices, just another (additional) way to write "please send the due funds to ".
How does the employee at the till know if the transaction was successful?
Just as they do know: The till will tell them that the customer has paid.
Which is why I said that this QR code thing is much more useful for situations where there's no till in the first place, like a flea market, where a QR code + looking at the transaction log on your phone can make a shoddy yet serviceable till. Certainly better than telling people to go to an ATM if they want to buy something.
@oakward@feddit.org cool, I can see my comments from lemmy on mastodon, I am curious if comments from mastodon make it across to lemmy.
I am amazed
