Description
DESFire | NXP MIFARE® DESFire® EV3 2K Green Key Fobs, No Imprinted Number
Equip your access control or identification system with NXP MIFARE® DESFire® EV3 2K green key fobs designed for secure, convenient 13.56 MHz contactless credential applications. Each compact RFID key fob incorporates an NXP MIFARE DESFire EV3 contactless IC with 2K Bytes of nonvolatile application memory, advanced cryptographic capabilities and a flexible multi-application architecture.
The distinctive green fob housing provides an easy visual method for identifying departments, user groups, membership levels, visitor categories or access classifications. This configuration is supplied with no visible imprinted number, creating a clean, uncluttered credential surface when external numbering is not required.
These DESFire EV3 2K key fobs are well suited for compatible corporate access control, education, healthcare, government, transportation, parking, membership and multi-application credential systems requiring advanced security in a practical key-ring form factor.

Green Color-Coded Credential with a Clean Surface
Green key fobs can help administrators visually distinguish one credential group from another without changing the underlying DESFire EV3 technology. Organizations may assign the green housing to a particular department, building, user type, membership level, visitor category or access classification.
This configuration does not include a visible imprinted number. The clean exterior is ideal for credential programs that do not require factory-applied external numbering or that identify credentials through their own internal administrative processes.
NXP MIFARE DESFire EV3 Security and Performance
MIFARE DESFire EV3 was developed for secure, interoperable and scalable contactless applications. Its flexible architecture allows compatible systems to organize applications, files and access keys according to project requirements while supporting established cryptographic methods and secure communication.
- AES-128 Security: Supports AES-based authentication and secure messaging for compatible deployments.
- Triple-DES Support: Supports DES, 2K3DES and 3K3DES cryptographic methods for applicable systems.
- Transaction MAC: Helps compatible applications verify the authenticity and integrity of transaction data.
- Multi-Application Architecture: Allows multiple independent applications and files to coexist within the available memory.
- ISO-Based Communication: Complies with ISO/IEC 14443 Type A contactless communication requirements.
- Fast Data Transfer: Supports communication rates up to 848 kbit/s when used with compatible reader infrastructure.

Compatibility Notice
MIFARE DESFire credentials are not universally interchangeable. Reader compatibility, application keys, encryption method, file structure and system configuration must be confirmed before ordering. A reader operating at 13.56 MHz is not automatically compatible with every DESFire credential. The system must specifically support MIFARE DESFire EV3 or an applicable backward-compatible DESFire operating mode.

Frequently Asked Questions
Does this green DESFire EV3 key fob have an imprinted number?
No. This configuration is supplied without a visible imprinted number, providing a clean exterior surface.
Why choose a green key fob?
A green housing can help visually separate credential groups, departments, locations, visitors, membership levels or access classifications.
How much memory does this DESFire EV3 fob provide?
Each key fob provides 2K Bytes of nonvolatile application memory.
Does this credential support AES security?
Yes. MIFARE DESFire EV3 supports AES-128 authentication and secure messaging, along with DES and Triple-DES methods for applicable deployments.
Can this DESFire EV3 fob support multiple applications?
Yes. Its flexible application and file architecture can support multiple independent services within the available memory, subject to system configuration.
Will this fob work with any 13.56 MHz reader?
No. The reader and host system must specifically support MIFARE DESFire EV3 or a compatible DESFire operating mode. Operating frequency alone does not establish compatibility.
Is DESFire EV3 the same as MIFARE Classic?
No. MIFARE DESFire EV3 and MIFARE Classic use different memory structures, security methods and application architectures and should not be treated as interchangeable.
How many green DESFire EV3 key fobs are included?
This listing includes 100 green DESFire EV3 2K key fobs.
