CardOS is a smart card operating system from Atos (formerly owned by Siemens). It is dedicated to Infineon smart card controllers like the SLE78CFX3000P.
On the one hand it is a classical multi purpose ISO 7816 operating system. On the other hand it is also an operating system in accordance to signature laws. The architecture of CardOS is based on the idea of a general purpose platform with a number of loadable standard packages depending on the target application / project to be implemented.
For integration purpose middleware products like CSP and PKCS #11 can be offered.
United Access is a value added reseller for CardOS smart cards or modules. United Access also provides first and second level support for this operating system.
