PRX-TAG

An extremely durable compact design offers the ultimate reliability and convenience, while the IP68 rating means these tags are resistant to heat, pressure and chemicals, making them suitable for the harshest of environments.

  • Utilizes highly secure 13.56MHz MIFARE DESFire EV1 or EV2 smart card technology
  • Mutual authentication, AES 128, DES and triple-DES data encryption with unique 56-bit serial number
  • Improve security of existing 125kHz applications with dual technology transition tags
  • Open solution with read / write functionality
  • Overmolded design prevents access to the tag's components
  • Laser engraved tag identification
  • Environmental rating of IP68 ensures maximum durability

Features

ICT Secured MIFARE is ICT's implementation of the MIFARE standard. Credential data is protected with a diversified authentication key and encrypted with an AES 256 algorithm, effectively plugging the known security flaw in the MIFARE standard.

Other MIFARE formats are also available.

Designed for a diverse range of applications that demand the highest levels of security, MIFARE DESFire EV2 is based on open global standards for both RF interface and cryptographic methods.

The highly secure micro controller-based solution is certified with Common Criteria EAL5+. It features an on-chip backup management system and mutual three pass authentication, allowing it to hold up to 28 applications and 32 files per application.

125kHz technology offers a lower level of security but a good read range and short read time due to the lower power requirement and the small amount of data being transmitted. This allows users to simply present, swipe or wave their card in the general direction of the reader to achieve a successful read.

The thin, compact design allows the tag to be carried in a wallet or purse, or easily attached to a keyring. Use with a lanyard or strap clip for maximum accessibility.

An extremely durable compact design offers the ultimate in reliability and convenience, while the IP68 rating means tags are resistant to water, heat, pressure and chemicals, making them suitable for the harshest environments.

Migration from legacy and less secure low frequency 125kHz technology can be easily achieved using dual technology DESFire cards that incorporate both high and low frequency tag inlays. This allows organizations to transition to smart readers at their own pace.

Support for a number of low frequency products is available.
