ACS develops smart card operating systems (ACOS) as its intellectual property. Developed by our dedicated team of specialists, the ACOS3 Microprocessor Card unlocks the potential of a smart card. It enables a single card to support various applications such as loyalty program, parking registration, access control, eID, and electronic purse.

ACOS3 is specifically designed for highly secure payment applications. Featuring a high degree of security, ACOS3 is particularly suitable for secure loyalty programs, identification, and e-Purse applications. Likewise, it may be utilized for common payment solutions.

Additionally, security provided by ACOS3 may be further enhanced by utilizing ACOS6-SAM, which, by enabling Mutual Authentication, Secure Messaging, Key Diversification, and Key Injection, perfectly secures various applications.
