LEGIC Master-Token System-Control

Security in your hands

The patented LEGIC Master-Token System Control is the key for secure and easy management of contactless smartcard applications. The Master-Token is the main element of the security concept providing full control over the system. The possession of a unique and uncopyable physical medium therefore means more security for the owner. The Master-Token System-Control as a security solution allows a flexible and open use of the LEGIC technology platform.

The principle of the Master-Token System-Control corresponds to an evolutionary family tree and allows the administration of different applications. A ‘genetic code’ makes each organizational unit unique. It serves the purpose of identification and traceability and ensures the security of a specific application. The Master-Token is the main element when initializing identification media and transferring authorizations to the reader.

The security of a contactless smartcard system mainly depends on the technology used. The unique Master-Token Zone concept takes the technology generation of the medium and the Master-Token into account. The Zone concept ensures that a Master-Token always corresponds to the security standard of the associated transponder technology and enables therefore a secure, long-term operation of the system. If required, a technology can be selectively deactivated. The technology generation of the Master-Token is inherited when generating LEGIC segments on ATC256-MV410, ATC1024-MV010, ATC4096-MP311, CTC4096-MP410 / MM410 and AFS4096-JP1x. This enables readers to specifically exclude individual segments based on their technology origin.

Instead of securing administrative rights in an ID system with volatile passwords, the security with MTSC is linked to a special, physical smartcard, the Master-Token. No personal data is stored on this special smartcard. The owner has the authority over an installation and preserves his independence. The Master-Token can be stored securely, transferred to trusted people and withdrawn again at any time. Only the Master-Token enables the authorization of readers and the creation of identification media and further Sub-Master-Tokens.

The Master-Token System-Control enables the simple and intuitive implementation of authorization hierarchies without the use of data and information in plain text. A Master-Token can be used to generate on so-called Blanks various Sub-Master-Tokens with different genetic codes. These can be specifically allocated to different applications, company branches, suppliers or even customers. If a reader is initialized with a Master-Token of higher hierarchy, it has access to all applications of the corresponding Sub-Master-Tokens.

The Master-Token System-Control security solution increases the flexibility and openness of the LEGIC technology platform. It is, for example possible to combine applications from different providers in one system and to add or remove applications at any time. This keeps the system attractive and secure in the long term

entryMTSC at its best!

Do you always know where your password or key is?
Do you intend to be independent from the supply chain?

With a physical Master-Token System-Control, you always know exactly where your secrets are stored.
Furthermore, you are fully supplier independent as you have everything needed in your own hands.

LEGIC’s MTSC is the recognized and proven solution for secure and easy management of contactless smartcard applications.
The Master-Token itself is the central element in this security concept and grants full control over the system management.

Until now, the LEGIC patented security concept has only been available to all ID Network Partners.
An extension of this concept is the new entryMTSC, a project-based Master-Token that all customers can purchase, irrespective of partner status!


The entryMTSC is available through any LEGIC license partner or directly on the LEGIC "Secure Extranet". It is sent in a box containing three cards (1 GAM, 1 IAM and 1 SAM) protected against any electromagnetic field fraud.

Businesses with hundreds of cards with a specific need for security and sovereignty for their contactless applications can benefit from Master-Token System-Control. With the LEGIC entryMTSC you have the master key for the deployment of one application in your hand.  The entryMTSC is future-proof and scalable: multi-application is possible by simply adding an additional IAM/SAM. Experience the potential of LEGIC MTSC in a simple and cost-efficient way by trying the entryMTSC without becoming a LEGIC license partner. If you later intend to expand to more than one application, you can buy another entryMTSC or become a LEGIC licensee.
