Flexible Communication

The system supports:

  • The basic communication protocol, ISO 7816 T0, and alternative communication protocols, namely, ISO 7816 T1 and ISO 14443 Type A&B Contactless.
  • USB (Universal Serial Bus) interface
  • Extended APDUs.
  • Secure messaging Via Global Platform Security Protocols (SCP02 & SCP03)

Multiple Delivery types

      • Wafer Swan
      • Contact Card
      • Contactless Card
      • Dual (contact and contactless) Card
      • USB Stick
      • Dual (USB and contactless) Card


Biometric OS

Biometric Smartcard Operating System


TrustSEC BIO-SLCOS-SLC38 is an updated version of SLCOS that enables MOC feature. The Match-on-Card (MoC) stores the holder’s biometric data and protects such communications with encryption, which enables the biometric authentication to be executed entirely within the secure element.


BIO-SLCOS-SLC38 enables smartcard-solution-based providers to easily cope with the latest integrated technology with secure elements, using SLCOS with the ability to add an extra layer of security “fingerprint-authentication” and the flexibility to add other applets on the card as well.


Highly secure

TrustSEC smartcard OS SLCOS is designed, and well-tested to perform cryptographic operations with the highest measures.



SLCOS has been fully developed in-house, that added to its advantages the high flexibility. Also, the high-performance architecture of SLCOS allows issuing multi applets on the card.





Adaptation of the smartcard based on the client’s requirements with the possibility to include proprietary Cryptography. 

OS Operations

Smartcard OS Operations

This system is responsible for providing the following operations:

      • Manages the smart chip hardware and perform chip initialization, configuration while startup and self-test
      • Manages single or multiple applications. Application management includes, secure download, loading, installation, selection, communication and deletion
      • Optionally allows multiple vendors per card using multiple security domains
      • Secure application execution in multi-applications environment using either software firewalls or hardware MMU
      • Executes high level applications through internal virtual machine
      • Provides software level implementation for cryptographic operations like RSA, ECC, DSA, DES, 3DES, AES, SHA, PRNG and DH
      • Provides software level implementation of communication protocols like T0, T1, TCL and optional USB/CCID
      • Provides system level interface for different hardware modules like communication, security, storage, memory, transaction, file system, timers and random number generator
OS Applications
