transponders, in comparison to a competitive card reader,” said Klaus Schoeke, Vice President of
Technical Sales for FEIG ELECTRONIC.
All cryptographic functions established in the secure messaging scheme of the MIFARE DESFire EV2
and NTAG 424 DNA are performed by the CPR74 firmware making application development for the
card reader much faster and more straightforward since the developer is not required to have an
understanding of the lowest level functions of the protocol’s challenges, authentication, and
encryption.
The CPR74 has an integrated onboard antenna as well as an external remote antenna port that is
multiplexed with the onboard antenna. The antenna functionality is configurable and may be used as
addressable individual read points.
The CPR74 reader supports the complete range of MIFARE IC’s as well as the new NTAG 424 DNA
line. NTAG 424 DNA is an attack resistant, certified chip platform, providing AES-128 cryptographic
operation for security and privacy in NFC smart product applications, to fight against counterfeiting
and grey market activities. In addition, the NTAG 424 DNA TagTamper variant is used to detect
product tampering. The CPR74 also supports the recently introduced MIFARE DESFire Light, a next-
generation lightweight version of the MIFARE DESFire family that simplifies the introduction of single
application contactless services.
The MIFARE DESFire EV2 IC fulfills the requirements for fast and highly secure data transmission,
flexible memory organization and is interoperable with existing contactless infrastructures. “Future
MIFARE IC releases will incorporate the advanced encryption standard,” said Martin Liebl, senior
director product management smart mobility and retail at NXP Semiconductors. “FEIG customers’ are
able to ‘future proof’ their RFID enabled products and extend their product life cycle through FEIG’s
firmware releases that extend support to the latest silicon releases brought to market by NXP.”
Companies that use the CPR74 as their card reader platform are able to update existing deployments
of the FEIG module simply to the latest silicon releases offered in the market. The firmware is
available for download at no charge to FEIG customers.
Smartrac Technology Group, a global leader of RFID products and IoT solutions further commented:
"We are keen to use FEIG’s CPR74 for DESFire EV2 authentication in order to provide secure keys,
encode memory and lock access in NXP's NTAG 424 DNA chips, supporting our portfolio of secure
authentication RFID inlays and tags,” said Sebastian Zeidler, Senior Subject Matter Expert at
