Description

This product is not recommended for new designs. Instead, we recommend to use NXP’s MIFARE DESFire EV3 IC.

The NXP MIFARE DESFire EV2 2K is the latest addition to the MIFARE DESFire product family introducing new features along with enhanced performance for best user experience. The MIFARE DESFire EV2 is Common Criteria EAL5+ security certified which is the same security certification level as demanded for smart card IC products used e.g. for banking cards or electronic passports. It fully complies with the requirements for fast and highly secure data transmission and flexible application management. This makes it the ideal product for service providers and service operators who want to offer an easy, convenient and secure access to a wide variety of different services.

NXP has been working closely together with leading system integrators and solution providers to define and implement the next generation break through features which significantly enhance the customer experience whilst enabling new business models based on the next level of transaction security and private data protection.

The second evolution of the industry-leading MIFARE® DESFire® ICs offers superior performance, state-of-the-art 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 unrivalled end user experience in mobile ticketing.

MIFARE DESFire EV2 offers best flexibility when creating multi-application schemes and features such as MIsmartApp with multiple key sets and Transaction MAC are supporting new business models. Smart Cities services for example could be utilized with only one MIFARE DESFire EV2 card by combining services such as public transportation, car or bike sharing, access to city attractions with citizen services, closed-loop e-payment applications and local loyalty programs.

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. The size of each file is defined at the moment of its creation, making MIFARE DESFire EV2 a truly flexible and convenient product. An automatic anti-tear mechanism is available for all file types, guaranteeing transaction oriented data integrity.

The main characteristics of this device are denoted by its name “DESFire”: DES indicates the high level of security using a 3DES or AES hardware cryptographic engine for confidentiality and integrity protection of the transmission data. Fire indicates its outstanding position as a Fast, Innovative, Reliable and sEcure IC in the contactless proximity transaction market.

MIFARE DESFire EV2 delivers the perfect balance of speed, performance and cost efficiency. Its open concept allows seamless future integration of other ticketing media such as smart paper tickets, banking convergence card, and mobile ticketing based on Near Field Communication (NFC) technology. It is also fully compatible with the existing NFC reader hardware platform. MIFARE DESFire EV2 is your ticket to secure contactless systems worldwide.

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.
