The microcontroller in question is a NodeMCU and the application is to Verify payments for a vending machine. The machine displays a QR code for customers to pay through the Google Pay App. The requirement is to check the bank account for an increase in balance and verify a payment. I have no experience with the Google Pay API so please suggest the process. If there's a better platform for payments and verification please feel free to suggest.

It looks like this specifically a Google Pay thing and unfortunately Stripe doesn't support that Google Pay functionality directly.
Since this wouldn't work at all for i.e. iPhones, and since I presume you have some kind of server-side application here anyways, you may just want to instead consider building a web app that the QR code directs to, that allows payment in more ways than just Google Pay.
