产品描述

MIFARE DESFire EV1 256B (MF3ICD(H)Q1), is the future proof entry level product of thewell-established MIFARE DESFire family and is addressing applications with low memorybut high security and data integrity needs.

The MIFARE DESFire EV1 256B offers the same security and file creation features as thehigher memory family members (Ref. 1), but the number of applications and related fileson this product is limited due to its small memory plot.

This addresses the needs of account based systems and environments requiring only alimited set of applications.

These applications include but are not limited to access management, public transportticketing, loyalty schemes and closed-loop payment.

It is fully compatible to all other members of the MIFARE DESFire EV1 family, offeringthe same fast and highly secure data transmission, and is fully interoperable withexisting MIFARE DESFire infrastructure.

All MIFARE DESFire products are based on open global standards for both air interface andimplemented cryptographic methods. It is compliant to all 4 levels of ISO/IEC 14443A anduses optional ISO/IEC 7816-4 commands, features an on-chip backup management system andmutual three-pass authentication as well as encrypted communication.

The size of each file is defined at the moment of its creation, provides an automaticanti-tear mechanism for all file types, guaranteeing transaction-oriented dataintegrity. Data transfer rates from up to 848 Kbit/s can be achieved, allowing for fastdata transmission.

The main characteristics of the MIFARE DESFire family are denoted by the name “DESFire”:“DES” indicates the high level of security using a hardware crypto co-processor foreither 3DES or AES-based data processing. “Fire” indicates its outstanding position as afast, innovative and highly reliable IC ideally suited to enable a wide variety ofdifferent applications.
