The MIFARE DESFire EV1 4K
(NXP model MF3ICD41) is a high-security, multi-application
contactless smart card IC operating at 13.56 MHz. It is part of NXP's
premium DESFire family, designed for applications requiring robust encryption
(AES/3DES), a flexible file system, and reliable performance in public
transport, access control, and e-government systems.
1. Core Definition
The DESFire EV1 4K is a passive
(battery-free) ISO/IEC 14443-4 compliant chip featuring 4 KB (4096
bytes) of EEPROM memory. Unlike older MIFARE Classic cards, it functions as
a true smart card with a dedicated cryptographic co-processor and an
operating system that supports multiple isolated applications on a single card.

3. Memory & File
System
The 4 KB memory is managed
via a flexible file system (not raw sector blocks like MIFARE Classic):
- File Types:
Supports Standard Data, Value (for e-purse), Linear Record, and Cyclic
Record files.
- Structure:
Up to 28 Applications (App IDs), with up to 32 files per application.
- Access Rights:
Each file has configurable access permissions (Read/Write) tied to
cryptographic keys.
4. Security Features
- Hardware Crypto:
Dedicated co-processor for AES-128, 3DES, and DES
encryption. Data on the RF channel is fully encrypted.
- Authentication:
Mutual three-pass authentication (ISO/IEC 7816-4 based).
- Anti-Tear Mechanism:
Hardware protection against data corruption during sudden removal from the
RF field.
- Privacy:
Supports Random ID (RID) mode to prevent tracking of the card's
unique 7-byte UID.
5. Common Applications
- Public Transportation:
Electronic ticketing, season passes, and multimodal fare systems.
- Secure Access Control:
Corporate and government building access (PACS).
- E-Government:
National ID cards, health cards, and social benefit cards.
- Campus Cards:
University IDs combining access, library, and payment.
- Closed-Loop Micropayment:
Vending machines, canteens.
