Hi guys, Does anybody here have an understanding of POS (point-of-sale) technology. I am looking for a way to print a QR-Code onto a till receipt if the dollar spend is over a set amount. The QR-Code information to be printed would be pulled from a 3rd party server. Every till receipt that is printed with a QR-Code would have its own unique QR-Code on it. The QR-Code that is printed can be scanned by a QR-Code reader and be recognised by the backend of the server that created that QR-Code. So basically it sends the till information to the server and the server sends back the printed information with a QR-Code.This QR-Code is scanned and is recognised by server and performs some other action. Is this possible without POS integration? Would I be correct in presuming the POS will have to be networked? What make/model of printer would you suggest? (wifi enabled) Can anybody shed some light on this for me. Thanks in advance.
