Hello.

Yes, we know that. The UID of the new card is 7 bytes long, UID of the older cards only 4 bytes. That is no problem for our print solution, only the terminal to pay money to enhance the value of their print accounts does not read the UID exactly. We thought we can translate the 17 digits of the 7 bytes UID in 10 digits like the older Cards, so described here: https://www.nxp.com/docs/en/application-note/AN10927.pdf (3.3.2)

Is that a possible way?

Thanks
Andreas
