Thales in the Czech Republic employs over 400 people from 45 different nationalities. A total of 15 teams work on projects for government agencies, banking, mobile services and the Internet Of Things (IoT) technology. At the core of our business is the development of software which we configure and embed in a multitude of different devices and form factors. These include many kinds of payment cards, SIM cards, travel passes, secure eBanking devices, authentication tokens, machine identification modules (MIM), and secure ID documents including ePassports, eID and eHealth cards, as well as eDriving licenses. Because of the international environment surrounding us every day, it comes as no surprise that English is our official corporate language.
