| ACS develops smart card operating systems (COS) as intellectual
property. ACOS1, unlocks the potential of smart cards, enabling a single
smart card to support applications as diverse as loyalty, parking, network
access control, transport, telephone and electronic purse.
ACOS1 smart card is specifically designed for highly secure payment
applications. With this high security feature, ACOS1 is particularly
suitable for applications such as network access control, electronic
purse and multitude of other applications that stress high security.
ACOS1 smart card is known among smart card system developers that it is secure
but is easy to use. The design is often said to be 'secure and
elegant'.

features |
- Digital Encryption Standard (DES) -- Ciphering is used in this
mode of protection, which is like translating the information into
some unknown foreign language, so the stored information can be
transmitted confidentially. Simple DES or Triple DES versions are
both available.
- Message Authentication Capability (MAC) -- This is based on
the exchange and mutual verification of secret passwords [keys]
between the card and the card-accepting device. The whole
verification process is done within the device and information is
never transmitted outside during the process, making eavesdropping
virtually impossible.
- Enforced Message Authentication with random numbers and
dedicated key pair.
- Continuous system integrity checks guarding against attempted
security breaches
- Five secret codes + Issuer Code + Pin to selectively enable
access to data stored in smart card and to features and functions
provided by the card e.g. the READ and WRITE commands.
- Account Transaction Processing (ATP) provides dedicated data
structure for payment applications with CREDIT, DEBIT, INQUIRE
ACCOUNT commands for secure transaction processing.
