CWORK® Security Measures
CWORK® is compatible with all major public certification cards distributed by public institutions and equipped with IC chips. The chip has been certified to ISO/IEC 15408, an international security standard, and various countermeasures are in place to prevent unauthorized data writing and theft. Unlike the face of the card, which can be printed illegally, it is difficult to use fraudulently. The IC chip records only basic information such as name and address, and does not record highly private information such as tax and pension information.
