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.

MA1 use 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 MA1 Secure series uses an EAL5+ cryptoprocessor to improve protection and privacy.

Security between card and OEM module

MIFARE Plus®: with different levels of security and the AES encryption (128 bits keys) of MIFARE Plus®, you strengthen authentication and confidentiality of the data.
DESFire® EV1 & EV2: thanks to the TDES and AES cryptography algorithms, you are guaranteed with a top security level permitting to control up 28 different applications per card.

Security between OEM module and system

The MA1 MIFARE Plus® / DESFire® EV1 provides high level of security between the module and your access control system thanks to the secured SSCP protocol (STid Secure Common Protocol). It uses standard algorithms (AES and HMAC-SHA1) for a high security level and fast authentications.

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.

This module makes updates fast and easy. Updates and upgrades can be done remotely and do not require any on site intervention.



Easy integration and migration

The MS is the best choice for your identification and high security applications. The MIFARE® compatibility will enable you to gradually upgrade the existing users to a new solution.



Examples of integration:

  • Restricted areas
  • Handled terminals & readers
  • Fast access corridors / gates…

Easy to install

Ma1 versions us en



MA1 is a mullion RFID reader specially designed for installation in small spaces, for example on door frames or narrow flushbox mounting.

Its small size and intelligent design make it easy to incorporate into any installation environment with no spacer required (included on metal).

The plug-in/plug-out connector cable and the round mounting holes make the installation easier
