NFC reversed hex on Samsung phones is constantly different. How to fight?

Question

Android

NFC reversed hex on Samsung phones is constantly different! Those. we scan one and return the other, how can we deal with this

Answer 1

I don’t know what “reserved hex” is, when working with NFC in Android, usually the read data is returned as an array of bytes - byte[]
If you do not take into account that this is an array of bytes and try to work with a string, the string will look different each time.
Convert byte array to string
