Apple Pay as an Entry/Exit system

We have a parking garage system that works with RFID-tags or Credit Cards. The user use the tag/card when he enters and exits. Charging is via invoice for tags or via the Credit Card. Now we (our customers) want to use Apple Pay to Enter/Exit. Here we got a problem. Apple Pay generates a unique ID for each use. So we can not match an entry with an exit.

Is there a (simple) way around this or for this?

(I am not the developer of this system)
