I have been looking into getting a chip for our access systems at work. The security people tell me we use Mifare and that they will have no problem assisting in registring the UID of compatible chips for me so there’s no need to clone something.
Currently we’re using coins and cards at the office.
I scanned both with TagInfo and this is what they came back as.
Mifare Classic: MF1S50
Full name: MF1S5037
UID format: XX:XX:XX:XX
ISO/IEC 14443-3 (Type A) Compatible
ISO/IEC 14443-2 (Type A) Compatible
