Semiconductor ICMIFARE DESFire EV3 4K
Interface / protocolISO/IEC 14443 Type A, parts 1–4 · NFC Type 4
Nominal memory4 kB
RF data rates106, 212, 424 and 848 kbit/s
Identifier7 byte UID; optional random identifier
Cryptographic optionsDES, 2K3DES, 3K3DES and AES 128
Files per applicationUp to 32
Application capacityDetermined by allocated memory

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.

EV3 adds Transaction Timer and Secure Dynamic Messaging. These features require deliberate system configuration.

Reader compatibility and manufacturing 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.

Select a finished product above for format specific guidance on dimensions, attachment, antenna placement and operating conditions.

State your required product model, IC order code, printed identifiers, encoding format, initial volume and delivery destination. Roxtron confirms the complete production specification and quotation before manufacture.
