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

Readers can read:

  • NXP MIFARE credentials (Classic & Classic EV1, Ultralight® & Ultralight® C, Plus® & Plus® EV1, DESFire® 256, EV1 & EV2),
  • French Ministry cards (“Carte AGENT”, CIMS…) and civil aviation (STITCH),
  • CPS3 (IAS protocole) health cards,
  • smartphones compatible with Bluetooth® and NFC (HCE) technologies.
  • 125 kHz credentials  (EM, Crosspoint, formats Wiegand 26, 34, 35 and 37 bits…).

Access control with the smartphone

Discover the 6 modes of identification for a unique user experience!

Virtual cards promote acceptance of and compliance with the Security Policy of businessesindustries 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!

Welcome to high security

Logos representing the high security of the ARCS-I/BT by STid Industry

All public encryption algorithms can be used (3DES, AES, RSA, SHA, etc.), which are recommended by official data security agencies (such as the French national agency ANSSI). 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.

  • 100% local sandboxed programming
  • Autonomous management for securely programming RFID and Bluetooth® user cards
  • Configuration and reconfiguration of readers
  • Protection and confidentiality of user cards and the master card
  • Plug & Play tool
  • Fully compatible with AGENT, CIMS and STITCH cards
  • Complies with General Data Protection Regulation no. 2016/679 and Standard EN16571

logo sia osdp

Readers are compatible with the SIA Open Supervised Device Protocol - OSDP™ V1 & 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.

Standing the test of the time

Design to push the boundaries, the Architect® Blue Hybrid reader design has been developed to withstand harsh environments, to operate outside (IP65 level) and to offer a high vandal-proof resistance (IK10).
