Contactless Card Reader Integration for Turnstile like Amazon Go Stores

Our store concept involves turnstiles that accept credit card taps for preauthorization. Customers can freely shop, and remote employees monitor via cameras, charging the correct items upon exit. I need the turnstile to facilitate seamless credit card transactions, enhancing the self-checkout process.

I need assistance in choosing and setting up a card reader system that will allow for a lot of pre authorizations and manual charges for customers' virtual carts.
