The MIFARE Ultralight EV1 features three independent 24-bit one-way counters to enhance trip counting, reloading, limited stored values, and expiry date management. It comes with a 48-byte or 128-byte programmable user memory and fast-read command to retrieve multiple memory pages with a single command.
A 32-bit password protects data from being accessed without authorization. NXP’s “originality signature” enables vendor verification of each single IC, contributing to a more reliable system and enabling transport operators to identify and reject tickets that aren’t qualified to work in the specific application.
MIFARE Ultralight EV1 is backward-compatible with MIFARE Ultralight as well.
