How to identify an Android smartphone via NFC?

Question

Android

There is an RC522 in conjunction with an Arduino Nano. You need to use it to make a device to which if you attach an Android smartphone (Samsung s10 +), then the Arduino will perform certain actions, depending on the smartphone ID (they will be written in the code).
The problem, in fact, is identification. When I put my smartphone on, the Card UIDs take on random values ​​every time. Accordingly, it is impossible to use them for identification.
How can I identify a smartphone using RC522?
