Many of the largest retailers have custom POS systems. I'm trying to understand the level of build required to generate QR codes that are compatible with most POS systems out there.
QRs are simple links, typically URLs. To perform any kind of interaction with a 3rd-party system, you need to understand what parameters this system can take as part of a URL and see if it performs the expected use case well. My suggestion is that if you can generate the right use case by typing a URL in a browser, you can also support the same use case via a QR. The QR is not where the challenge is. I hope it helps
