NXP semiconductors has recently revealed its next generation of contactless paper ticketing ICs. The MIFARE Ultralight EV1 is a non-cryptographic product which addresses the demand for low-value or disposable tickets.

Leveraging smart paper tickets, transport operators can offer day passes or limited-use tickets for tourists and occasional travelers. Additionally, smart paper tickets enable public transport operators to run a fully integrated contactless system with only one reader infrastructure for cards and tickets, freeing them from the need to maintain systems for both mag-stripe and barcode-based tickets.

The new features of MIFARE Ultralight EV1, such as three independent 24 bit one-way counters, enable transport operators to integrate flexible ticket tariff schemes through enhancing trip counting, reloading, and limited stored values and expiry date management.

One application example is the use of multiple counters for a zone- or mileage-based tariff scheme in a check-in / check-out system. Another application is the smart combination of trip- and reload-counting. In addition, a new 32bit password protects data from being accessed without authorisation.

The NXP 'originality signature' enables vendor verification of each single ICthis contributes to a more reliable system and allows transport operators to identify and reject tickets which are not qualified to work in the specific application. Other specifications include a choice of 48B or 128B freely programmable user memory, a configurable limit of unsuccessful authentication attempts, and availability in a 75?m or 120?m thin bumped wafer.
