Cloning a Salto PFM04K tag?

I’m hoping to clone my apartment key, a NXP MIFARE Classic 4k, NfcA, MifareClassic, NdefFormatable, onto my NFC ring (TAG203 V1ntage.)

I’m learning as I go… I’ve been into locksport for years, but have just been exploring the tech side of locks/security. I’m playing around with some apps and a cheap Chinese reader/quiet from Amazon (libo 10 freq…)

I’m not looking to be spoon fed - but can you guys tell me if it’s possible, and point me in the write direction? I really appreciate it.

Sorry no, the Mifare Classic chip has a fundimentally different memory structure than the NTAG203 in your ring. Also the NTAG203 has a 7 byte UID while the Mifare Classic likely has a 4 byte NUID, and the NTAG203 has far less memory space as well. For many reasons, it won’t be possible.

Thanks so much for taking the time to reply. I appreciate it.
