The correct answer is:

device the size of a credit card that contains access permission data. (A)

Step-by-step explanation:

An authentication token, also known as a security token is a device used to authorize access to a network service. Tokens use the two-factor authentication method to ensure security of a system. Usually the authentication devices have access pins before access to the main tokens, and tokens are unique sets of numbers that uniquely identifies a user in a service, and they are changed frequently, usually within a 5-minute period.
