Leveraging smart paper tickets, transport operators can offer day passes or limited-use tickets for tourists and occasional travellers. 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, are enabling transport operators to integrate flexible ticket tariff schemes through enhancing trip counting, reloading, 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 32-bit password protects data from being accessed without authorization. The NXP ‘originality signature’ enables vendor verification of each single IC – this 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 48 byte or 128 byte freely programmable user memory, a configurable limit of unsuccessful authentication attempts, and availability in a 75µm or 120µm thin bumped wafer.
