- lxgr 2y agoFor MIFARE Ultralight, yes – it's essentially just a bearer token with no encryption/authentication. I believe there's a password mechanism, though, which might just be good enough for single-use tickets. That password can be derived/diversified from the card's serial number, making such a scheme still significantly better than e.g. simple QR codes. MIFARE Ultralight C and larger/more expensive chips allow challenge-response authentication, making them pratically uncloneable. These are usually used for reloadable and monthly passes.
