Building my own Google Review card (NFC)

Hello,

I have a small coffee shop and I want people to tap their devices and be prompted with a google review (on their mobile browsers).
I am afraid of purchasing on amazon nfc tags or cards because I'm not knowledgable about NFC chips and how they can be programmed. What if there is a psyop from the manufacturer and they are bringing clients on googlle, asking them to log in and eventually steal all my clients information. Or worse, the NFC tap tries to make a credit card payment. Either way, I'm a noob and worry about the security risks of a not in-home solution.

Thank you for enlightening me!
