the problem is simple, i can only scan the rfid tag once then it doesn't work anymore ...
if i reset the arduino it works again but that is not so useful
code is over 9000 characters so it is attached...

Do you have a shorter example that shows the issue?
Also, IIRC, some readers can be in a mode where they only report new tags. Do you have another to test with?
