Wouldn't QR codes have a risk of some kind of race condition if someone is able to scan it before the intended recipient?

I'd love to see a payment system using QRCodes and apps, like they have in China, but vendor-agnostic. Not controlled by two tech corporations. Something that would work online *and* in person. I'm intrigued by both InterLedger and CBDCs as potential ways of doing that.

The way it works in China is :
1) I order fried tofu from a street food cart
2) I use my payment app to scan the QR code on the side of their cart
3) I type my PIN into my app
4) The vendor checks their app and sees that the payment has been made
5) My part is done, and the vendor gives me my friend tofu
