Does the system of Clay also consists and utilize the use of NfC stands and QR codes? For example for restaurants etc. Also, can these reviews be tracked than?

I know google has a policy for review getting so I am wondering how are you all going around that? In my opinion I think it does not mirror real world interactions, businesses owners wouldn't ask for a google review if they knew the person was not happy with their work. Would love to hear how you guys are doing it or if its even a concern to you
