Welcome to high security

Anssi flat

STid is the first RFID manufacturer to have received First Level Security Certification (CSPN). It’s a recognition of our unique know-how, the technological and security expertise that are implemented in your access architecture, whether new or existing.

ARC-A reader uses the latest MIFARE® contactless chip technologies with new data security mechanisms. 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 Architect® Secure series (ARCS) uses an EAL5+ cryptoprocessor to improve protection and privacy.

  • 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

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.


Create your own upgradable configuration

The Architect® series is intuitive and dynamic, and consists of 5 interchangeable modules that can easily be connected to a common smart RFID core.

This easy and cost saving modular approach allows autonomy on the security access management.
