NXP Semiconductors N.V. has introduced a contactless development platform geared make headway in new and emerging business models for the smart card market. The MIFARE DESFire EV2 claims to deliver an improved operating range and security support from NXP's latest platform, MIFARE DESFire EV1, up to Common Criteria level EAL5+ MIFARE DESFire EV2 is an ideal platform to enable the smart infrastructures of tomorrow, stated the company.

With DESFire EV2 multiple applications, such as public transport ticketing, bike rental, access management, closed-loop payments, membership, loyalty programmes and much more, can now be integrated on a single smart card.

The MIFARE DESFire EV2 platform is fully backwards compatible with existing MIFARE DESFire installations, offering a fast replacement and migration for established providers wanting to upgrade their systems.

One of the differentiating features of NXP's MIFARE DESFire EV2 is the ability to seamlessly incorporate and add different applications onto the smart cards once they have been issued and are being used by consumers. In the past, adding new applications to a smart card already in circulation was cumbersome: updates typically required access to the master security key and so cards had to be recalled from the field. Different operating environments also limited the types of applications that could be loaded onto the card resulting in additional complexity when creating apps. Now, with the innovative MIsmartApp and an enhanced key management system developed for MIFARE DESFire EV2, independent system integrators can create a single application for different environments or card systems without the card provider sharing the master security key, noted the company.

The MIFARE DESFire EV2 development platform also includes the Transaction MAC (TMAC), a verification feature for card transactions. Ideal for contactless systems with multiple operators and/or merchants. The TMAC ensures that all payment claims to the merchant clearing houses are valid and can be processed. The TMAC allows the backend systems to detect forged transactions, a repeat of a valid transaction and unreported transactions.
