Belonging to the MIFARE DESFire family, the newest MF3D(H)x3 integrated circuit provides better performance with longer operating distance and better transaction speed compared to its predecessors. A comprehensive list of security features gives MIFARE DESFire EV3 more ways to protect your data and ensure privacy. Hardware and software are certified according to Common Criteria EAL 5+ and the chip complies with ISO/IEC 14443A 1-4 and ISO/IEC 7816-4, supporting a wide variety of open cryptographic algorithms based on DES, 2K3DES, 3K3DES or AES. The new Transaction Timer feature that can be used to set a maximum time per transaction helps mitigate man-in-the-middle attacks.
Smart City services running on the MIFARE DESFire EV3 chip can be deployed on smartphones and NFC wearable devices using the NXP MIFARE 2GO cloud service, which manages digital credentials based on MIFARE products and allows contactless payments or access to features using NFC-enabled devices.
To ensure a high-quality user experience, MIFARE DESFire EV3 offers increased range and speed compared to previous versions. The 70pF option can enable read range optimization for aspect ratios that require a small antenna. Transaction speed is up to 1.5 times faster compared to NXP's MIFARE DESFire EV1 IC, so operators can increase system performance and enhance the end-user experience without needing to upgrade their infrastructure.
