Install RFID reader to an iPad

I want to read RFID tags (10 numbers) with my iPad, what do I need?

Situation:

At our gaming club we have an iPad (2019) that register members that enter the club. I have built a Filemaker Solution that works as it should; The member enters her member number and presss return.

We also have an RFID key tag solution to our entrance, so members can enter the club witout the need of a physical key.

Now I’d like a solution where the members press her RFID tag against the iPad/Reader instead of typing the member number.

Questions:

• What hardware do I need to solve this?
• Does the iPad have a built in RFID reader? Or is the built in NFC reader/sender something else?

I have fulll experience with how the digits from the RFID tag works and the database solution, I built a similar solution with a Mac a while ago. I just want to know the best hardware solution for the iPad.
