The multi-technology Architect® Blue range makes it easy to manage extensions, upgrades and technology migrations:

QR Code

Multiple formats supported (1D & 2D Codes): QR Code, Micro QR Code, code 128, Aztec and Datamatrix. QR Codes can be generated by existing systems/software and used in paper format or directly on the smartphone (email, virtual cards, etc.).

Bluetooth® low energy et NFC

Your smartphone becomes your access key by eliminating the constraints of traditional access control. Choose your favorite identification mode and make your access options both secure and much more instinctive!


The reader supports the latest contactless MIFARE® DESFire® EV2 chips with new data securization systems: Secure Messaging EV2 and Proximity Check. It makes it possible to use public security algorithms (3DES, AES, RSA, SHA, etc.) recognized by specialized and independent bodies in the information security sector (ANSSI & FIPS).

Fast and easy identification to improve user experience

The Architect® Blue QR Code access control offers convenience to temporary visitors and is fully integrated into the global security organization. It improves the efficiency of visitor management for the building/security manager.

The QR Code module is designed to ensure successful identification in all conditions (full sunlight, reflections, etc.).

The QR Code module can be retrofitted to any existing compatible Architect® Blue reader.

Examples of applications

  • Visitor Management
  • Access control for temporary staff
  • Parking access control
  • Mobility
  • Space sharing and reservation of meeting rooms
  • Logistics - shipping & receiving

5 identification modes for a unique experience

Virtual cards promote acceptance of and compliance with the Security Policy of businesses, industries and governments.
STid Mobile ID® is so user-friendly that it makes identification instinctive.

Choose your favorite identification mode and make your access options both secure and much more intuitive!

Reader are compatible with the communication protocol SIA Open Supervised Device Protocol - OSDP™ V1 et V2

logo sscp

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.

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.
