Hi, Square forum support team, is there any built-in way to associate an order with a QR code?
Let’s say, for example, a customer pays for 5 music lessons, and we want to be able to track how many more lessons they have left.
If a customer were to check in physically in person, to complete a lesson, they would have a QR code on a receipt scanned or a QR code received via email that would track how many more lessons they would have left.
An employee would scan the code and then the inventory would decrease after it was scanned.
Does something like that exist built-in or would I need to complete this externally with a database and API?
