The new ACOS3 card from ACS is a flexible microprocessor smartcard with 32K bytes of EEPROM memory. Backwards compatible with ACOS2, it now supports 3 volt operation and PPS speed negotiation. The high degree of security enabled by this card allows users to consider high end payment applications, especially when used alongside the ACOS6 Security Authentication Module (SAM).
This version includes a built-in contactless MIFARE Classic 1K chip too, providing a useful combination that can be used for logical and physical access control and other such applications.
Plain white card. This card can not be SIM cut.
