NXP Semiconductors' MIFARE DESFire EV1 contactless microcontroller IC has been chosen to power the Automatic Fare Collection (AFC) scheme of Madrid’s public transportation system. MIFARE DESFire is an open architecture platform for end-to-end solutions and has been used a number of cities including London, New Delhi and Nanjing.
Operated by the Consorcio Regional de Transportes de Madrid (CRTM), the public transportation system covers the city’s urban metro, bus network and suburban rail network, which is run by more than 50 different private operators. In total, more than 1.8 billion journeys are taken across the network annually, and migrating to contactless AFC will enable the consortium to offer an improved service to its passengers.
In addition to offering data transfer rates of up to 848 kbit/s, MIFARE DESFire utilizes a Triple DES, 3K DES, and AES hardware cryptographic engine for securing the data on the smartcards and data during transmission.
Based on MIFARE DESFire EV1, NXP’s contactless IC technology will be used to drive all season tickets including subsidised travel tickets for younger and retired passengers.
“The ability of MIFARE DESFire to integrate security systems based on 3-DES and AES, and its evolution to more advanced products (like the MIFARE DESFire EV1), have been some of the reasons, among others, that have determined the choice of this product by CRTM as the technology for their tickets” said Antonio Rubio Fernández, Jefe del Área de Innovación Tecnológica, Consorcio Regional de Transportes de Madrid.
Henri Ardevol, Vice President and General Manager of Secure Transactions, NXP Semiconductors, added, “Due to the size of Madrid’s public transportation systems, CRTM wanted to deploy the most secure and scalable contactless AFC solution possible. As a result, our solution was required to undergo rigorous testing and piloting to ensure it fully met the needs of the consortium, thus demonstrating the superior features and security we’ve built into this product.”
