MIFARE DESFire EV2 4K IC specifications
| Specification | Details |
|---|---|
| Semiconductor IC | MIFARE DESFire EV2 4K |
| Interface / protocol | ISO/IEC 14443 Type A, parts 1–4 · NFC Type 4 |
| Nominal memory | 4 kB |
| RF data rates | 106, 212, 424 and 848 kbit/s |
| Identifier | 7 byte UID; optional random identifier |
| Cryptographic options | DES, 2K3DES, 3K3DES and AES 128 |
| Files per application | Up to 32 |
| Application capacity | Determined by allocated memory |
Memory and protocol values describe the IC. Actual read performance depends on the finished antenna, enclosure, reader and operating environment.
Define application identifiers, file types, access rights and key provisioning with the system integrator. Available application space depends on the file system and configuration.
Compatibility modes do not remove the need to validate reader firmware, authentication and transaction behavior.
Integration and qualification
Specify the application identifiers, file structure, authentication algorithm, key versions and access rights. Validate a personalized sample with the installed reader firmware and issuing software. A successful UID read is not proof that an application transaction will work.
Specify wrist size, fit, wearing duration and cleaning conditions. Test the credential while worn, including wet use when relevant to the approved construction.
Approve an encoded sample in the finished application before volume production. Define acceptance criteria for identification, memory access, printed data and repeated operation.
Define your production requirement.
