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.

The Architect® Wal 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 perfect integration in your environment


The STid technologies have pushed the traditional access control boundaries! With its slimline design, the Architect® Wal features problem-free handling and easy installation in all the European switch boxes (60 mm).

The removable connector and the round mounting holes simplify and reduce considerably the WAL reader installation time.

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.
