Change security level with ACR120U or ACR122U reader

[barackle]

Hi All,

I have got some Mifare Plus X 2k cards in original state that is Security Level 0. I read a lot about security levels, but I did not found how can I set up neccessary keys to switch SL0 to SL1. I found "Write perso" and "Commit perso" commands, but my reader (ACR120U) cannot send ascii commands.

Can anyone send me a "How To" document or some concrete examples about what commands (APDU codes?) I have to send to card?

ACR120U or ACR122U supports Mifare Plus in SL0 mode to switch SL1?

Thanks

Hello,

You can send write perso and commit perso in Hex command format to ACR120U/ACR122U. These are mentioned in MIFARE PLUS X product datasheet.
Mifare PLUS X is an export controlled product. The documentation is delivered as personalized material if there is a valid NDA in place. Do you have valid NDA with NXP?
Also could you please let us know company info, contact email etc. to support you?

Thanks and Regards,
Vijay

As i Understand ACR120, does not support mifare plus (4 bytes or 7 bytes UID). The ACR readers models that support Mifare plus are products with 4 digits in their reference as 1281 or 1222, not 3 digits references like 120. Regards,
