MIFARE DESFire EV1 256B (MF3ICD(H)Q1), is the future proof entry level product of the
well-established MIFARE DESFire family and is addressing applications with low memory
but high security and data integrity needs.
The MIFARE DESFire EV1 256B offers the same security and file creation features as the
higher memory family members (Ref. 1), but the number of applications and related files
on this product is limited due to its small memory plot.
This addresses the needs of account based systems and environments requiring only a
limited set of applications.
These applications include but are not limited to access management, public transport
ticketing, loyalty schemes and closed-loop payment.
It is fully compatible to all other members of the MIFARE DESFire EV1 family, offering
the same fast and highly secure data transmission, and is fully interoperable with
existing MIFARE DESFire infrastructure.
All MIFARE DESFire products are based on open global standards for both air interface and
implemented cryptographic methods. It is compliant to all 4 levels of ISO/IEC 14443A and
uses optional ISO/IEC 7816-4 commands, features an on-chip backup management system and
mutual three-pass authentication as well as encrypted communication.
The size of each file is defined at the moment of its creation, provides an automatic
anti-tear mechanism for all file types, guaranteeing transaction-oriented data
integrity. Data transfer rates from up to 848 Kbit/s can be achieved, allowing for fast
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 for
either 3DES or AES-based data processing. “Fire” indicates its outstanding position as a
fast, innovative and highly reliable IC ideally suited to enable a wide variety of
