The new MIFARE DESFire EV2 contactless IC further increases flexibility and is also available on NXP’s SmartMX secure smart card platform used e.g. for contactless bank cards and secure elements for the use with NFC enabled mobile devices providing good end user experience in mobile ticketing.

MIFARE DESFire EV2 is based on global open standards for both air interface and cryptographic methods. It is compliant to all levels of ISO/IEC 14443A and supports optional ISO/IEC 7816-4 commands (APDU and file structure supported) and is fully interoperable with existing NFC reader infrastructure.

Featuring an on-chip backup management system and the mutual three-pass authentication, a MIFARE DESFire EV2 card can hold as many applications as the memory can accommodate. Each application can hold up to 32 files with various data configurations.

INNOVATION IN MULTI-APPLICATION SMART CARDS

Compared to MIFARE DESFire EV1 a MIFARE DESFire EV2 chip can hold as many different applications as the memory size supports and new applications can be loaded after the card has been deployed into the market. A purse can even be shared between applications, for greater interoperability.

The MIFARE DESFire EV2 contactless IC brings many benefits to end users. Cardholders can experience convenient contactless ticketing while also being able to use the same device for applications such as student ID, closed-loop payment at vending machines, access control management, and loyalty programs. The innovative MIsmartApp feature enables new business models. System providers can offer or sell application space to third parties without having to share the master key. A MIFARE DESFire EV2 product-based card can hold as many different applications as the memory will support, and new applications can be loaded after the product is in the field. It’s like having an app store on a smart card. A purse can even be shared between applications, for greater interoperability.
