help on finding bussiness plugin

Hello,

what we are trying to acomplish is to generate a set of QR, one time codes, any mean to give our customers a limited offer and to check that they only use it once. We tought of something like coupons, but since we are managing different stores (chains/brands) we were thinking maybe there is a plugin that can generate a link that automatically validates and “spends” the QR or code?

We aren’t really sure what to look for, so we tought to ask here.

Thanks a lot.
