Password Authentication - Ntag213 + ACR122U

[marco_fogli]

I have a question about set the password on the Ntag213

I use the reader/writer ACR122U and i need to set a password on the Ntag213

Anyone have the correct sequence of APDU command for setting the password on the Ntag213?

And after the setting of the password, the sequence for remove this one?

Thanks in advance
