NXP MIFARE® DESFire® EV2 16K

The NXP MIFARE DESFire EV2 16K contactless IC is ideal for system operators and developers building reliable, interoperable and scalable contactless solutions. The second evolution of our industry-leading MIFARE DESFire family offers superior performance, security and enhanced multi-application support.

The second evolution of our MIFARE® DESFire® ICs offers a good performance, security, privacy and enhanced multi-application support to enable new business models. 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.

CONTACTLESS PERFORMANCE

For a truly convenient touch-and-go experience, MIFARE DESFire EV2 offers a significant increase in operating distance and speed compared to previous versions. The 70 pF option enables read range optimizations of small antenna form factors. MIFARE DESFire EV2 delivers the perfect balance of speed, performance and cost efficiency. Its open concept allows for the future seamless integration of other media such as smart paper tickets, key fobs, and mobile ticketing With MIFARE DESFire EV2, data transfer rates up to 848 Kbit/s can be achieved, making fast data processing possible.

SECURITY AND PRIVACY

MIFARE DESFire EV2 is based on open global standards for air interfaces and cryptographic methods. Proximity Check protects against relay attacks, while the Virtual Smart Card architecture anticipates future needs of privacy protection. Other features include an on-chip backup management system and mutual three-pass authentication. Additionally, an automatic anti-tear mechanism is available for all file types, which guarantees transaction-oriented data integrity. MIFARE DESFire EV2 is Common Criteria EAL5+ security certified which is the same security certification level as demand for smart card IC products used, e.g., for banking cards or electronic passports.

The MIFARE DESFire EV2 silicon solution is the consumer friendly choice for system design, with heightened security and reliability, using a DES, 2K3DES, 3K3DES and AES hardware cryptographic engine for securing transmission data.

DESFire’s are available in PVC and Composite PET/PVC card construction, the MIFARE DESFire EV2 card is exceptionally durable and can accept an embeddable SAM card for logical access and biometric ID systems.
