Welcome to high security

Logos representing the high security of the ARC-O by STid Industry

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-O reader use the latest LEGIC® 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).

Fingerprint management

logo cnil for ARC-O  

The reader offers several fingerprint management possibilities depending on your security needs.

  • Fingerprint templates directly stored in the RFID card (CNILFrench legislation compliance)
  • Fingerprint templates stored in the reader or in the system
  • Biometric derogation to manage one-time visitor or difficult finger etc.

STid provide smart software tools to stay in control of your security. SEGIC allows the user, the installer or the integrator to realize easily secure programming access readers.

logo sscp for ARC-M

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.
