how to read 7 bytes ID number with RC522

Hi all !
I'm trying to read ultralite tag ID with the RFID-RC522 board
ultralite tags ID is 7 byte long as oppose to Myfare classic that is 4 byte long.

I can just manage to read the 4 first bytes and the last one is even not correct !

do you think it is possible to read the whole ID number with RC522 ?



What code are you using ?
