Description

Akuvox KF03 – MIFARE® DESFire® EV3 8K RFID Keyfob

The Akuvox KF03 is a high-security 13.56 MHz RFID keyfob designed for modern access control environments that require enhanced protection, reliable performance, and strong interoperability.

Powered by MIFARE® DESFire® EV3 technology, the KF03 supports secure contactless identification and advanced encryption methods, making it ideal for commercial, residential, institutional, and enterprise access control applications. Its compact format and integrated attachment slot make it easy to carry on a key ring or lanyard for daily use.

The KF03 is engineered for dependable long-term use with 8 KB EEPROM memory, a 7-byte Static UID, and support for DES, 2K3DES, 3K3DES, and AES encryption algorithms. It also supports SUN message authentication for improved data protection and includes a transaction timer to help mitigate man-in-the-middle attacks.

Built with durable PC + ABS construction, the KF03 is suitable for everyday use in demanding access control environments. It also offers excellent endurance, with typical data retention greater than 25 years and a minimum of 1,000,000 write cycles.
