Multi-function touchscreen reader

Both a reader and a tactile keypad, it allows user identification by combining the reading of an RFID or virtual card with the input of a personal keypad code.
The same reader can also operate in multiple mode. It authorizes, for example, the reading of cards for personnel and the entry of codes for visitors or temporary workers.

The Architect® Blue Hybrid reader is the perfect choice for a smooth transition to secure authentication technology.

The reader uses the latest MIFARE® DESFire® EV2 contactless chip technologies with new data security mechanisms:

  • Secure Messaging EV2: secure transaction method based on AES-128 with protection against interleaving and replay attacks.
  • Proximity Check: improved protection against relay attacks.

The reader supports the use of public security algorithms (3DES, AES, RSA, SHA…) recognized by specialized and independent organizations in information security (ANSSI French cybersecurity agency and FIPS).

Best market self-protection

The innovative tamper protection system protects sensitive data and gives the possibility to delete the authentication keys (patented solution). Unlike the current solutions on the market, the reliability of the accelerometer based technology avoids it being outsmarted.

logo sscp US

Readers are compatible with the latest generation of open protocol SSCP® (STid Secure Common Protocol). This protocol recommended by ANSSI uses data encryption (AES) and two-way “reader-controller” authentication to ensure security before any communication is allowed between the reader and the management system.
