How can I get the NFT card to record and emulate its data?

[buoyant spindle]

It will first save my school card in a mobile application and then save it as it is, whatever data the recorded card gives. Then, when you press the button, I want it to mimic that data back so that I don't have to worry about carrying the card in vain. But I couldn't figure it out. Since I don't know what type of data the current card gives, I tried something but it doesn't work properly. The application records something and then shares something, but the other device does not accept it. I am probably recording something wrong, what should I do?
