Which of the following is NOT a type of ACS card?

The classification of ACS (Access Control System) cards includes various types designed for access management and security purposes. An employee ID card, visitor pass, and access control badge are all specifically utilized within a security framework to manage entry and monitor who has access to certain areas. These cards are integrated with systems that track and validate personnel or visitors.

The social security card, however, is primarily a government-issued document used for identification purposes and to benefit from governmental programs. It does not serve the function of regulating access to physical locations or systems, which is the primary role of ACS cards. Hence, it does not fit into the category of cards used for access control.
