Reading performances and reliability

With its integrated antenna, the MS module provides all the functions of a proximity reader and outstanding reading performances.


Easy integration and migration

The MS OEM module is an obvious choice in all your identification, proximity access control and time attendance applications. It is extremely compact and very easy to integrate in almost all environments (handled terminals, embedded applications ...). Thanks to a wide choice of communication protocols, it will be immediately compatible with your existing systems. Its external antenna makes it adaptable to many mechanical constraints.

Examples of integration:

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