NXP Launches Next-Generation
Smart Paper Ticketing IC
The MIFARE Ultralight EV1 is an optimized ‘smart paper’ ticket IC with unique features which enable transport operators to enjoy more flexibility in ticketing and tariff schemes, extending options for limited-use applications and ensuring more reliable system operation.
As a non-cryptographic product, MIFARE Ultralight EV1 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 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. As well as reducing overall system and maintenance costs, the MIFARE Ultralight EV1 enables easy integration of multiple services such as tourist day passes and improves interoperability with the contactless reader infrastructure, which is largely based on NXP’s reader ICs.
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.
