MIFARE DESFire ® EV2 is an evolution of a high security chip developed by NXP. This 13.56MHz high-frequency technology RFID badge has a variety of applications thanks to its microprocessor and encoding algorithms, providing a high level of security for personal identification on sensitive sites.

DESFire EV1 Card Security

The DESFire EV1 card's 3DES encoding algorithm prevents pirates from reading or writing RFID chips, meeting the most critical security needs. DESFire ® complies with ISO 14443A 1-4 and guarantees anti-collision function. Each DESFire badge contains a unique UID serial number encoded in 7 bytes to guarantee its uniqueness and identification. This MIFARE DESFire ® badge is ideal for corporate access control, public transit passes, student ID cards or social security cards.

MIFARE ® chips with critical memory

We offer 3 versions of the DESFire ® badge with different storage capacities: DESFire 2K, DESFire 4K and DESFire 8K. The 4K version is the most common and specifically allows storing fingerprint-type biometric information for 1:1 identification on access control readers. This secure evolution of the MIFARE Classic® badge features flexible memory, provides fast data transfer, comprehensive security, and easily integrates with existing contactless RFID infrastructure.

Multi-Application 13.56Mhz RFID Card

The 4K DESFire card also allows you to use the same chip to control different applications: up to 28 applications, each with up to 8 security keys. Manage your high-security access controls, one of your other buildings or branches, parking lot access, your business catering, vending machines, copier access, etc...Using the MIFARE DESFire® Access Card gives you A range of possibilities.

Contactless Chip MIFARE DESFire EV1 to EV2 Evolution

NXP is developing its high security NFC chip! The electronic chip DESFire EV2 version appeared in the summer of 2019. With EV2, your access control card will be read faster because the communication distance between this RFID tag and the reader is increased.

DESFire Chip Version Compatibility

A feature that makes your life and access control system easier: DESFire EV2 is compatible with EV1 chip contactless function. This means you can buy EV1 and EV2 versions of the DESFire card for physical access control, and it works exactly the same way, just the newer version is more distant.

Other EV2 chip evolutions

Series of additional enhancements have been made, in particular to increase the security level provided in a DESFire card access control. But you can only benefit from these evolutions if your RFID readers and your application are compatible and can evolve to activate certain functions. The most significant developments are as follows.

Rotating DESFire keys

Access keys can be configured to rotate, no longer fixed. In the event of a security breach, the quarantine card's key can be modified without having to use all access control system cards to modify their DESFire keys.

Individual key management for each application

Key management is now separate for each application stored in a MIFARE DESFire EV2 card, which is by definition a multi-application chip (note that the number of applications is now unlimited, not before 28 application limit placed on EV1).
