EasySecure - Encrypted RS485 -> Plain Wiegand / Data/Clock or RS485 decoders

EasySecure - Encrypted RS485 -> Plain Wiegand / Data/Clock or RS485 decoders

The EasySecure decoder is a data encryption and authentication device for read-only readers. This smart decoder converts Secure RS485 channel into plain Wiegand or Clock&Data to be easily interfaced with existing access control systems.

The EasySecure decoder allows data encryption and authentication for high-security and Bluetooth® read-only readers. This intelligent device converts RS485 secure communication into a plain Wiegand, Data / Clock or RS485 communication compatible with the management system. Both the EasySecure decoder and STid’s readers ensure confidentiality and integrity of communication between the reader and the system.

Two versions are available:

  • RS485 encrypted – TTL (Wiegand / Clock&Data) plain mode
  • RS485 encrypted - RS485 plain mode

Read only and secured communication with decoder

Welcome to high security

Most access control systems provide unsecured communication links between the access control panel and the reader. Wiring is often a weak point where data can be sniffed and manipulated.
To protect against is this vulnerability, STid has developed the EasySecure decoder to be used in conjunction with the latest generation of contactless secure readers. This module secures the communication between reader and safe zone through data encryption (AES) and authentication procedure (SHA). The security decoder uses RS485 serial communication with the reader for flexible and easy wiring.


Logo of Anssi for the EasySecure

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.




  • Plug & Play integration: Wiegand, Clock&Data or RS485 serial
  • Data protected by SAM software similar to the CSPN certified reader
  • Interface configuration to control the reader by the SECard programming software SECard
  • Supports standard and specific diversification methods (AGENT, CIMS, STITCH French government cards...)
  • Tamper switch input on the interface to remove keys on the interface
  • Accelerometer tamper protection system on the reader: it gives the possibility to delete the authentication keys
