(Information about card readers and Magnetic Strips) ----->

Some security systems use card readers. A common type of card is a magnetic stripe card. A magnetic stripe card requires insertion or swipe at the point of use. The magnetic stripe card can become damaged over time and need to be replaced.

(Information about airport security checkpoints, their purpose, and how they are set up_ ----->

Airport security checkpoints would not be considered an access control system. This is due to the large amount of human involvement in the process. Access control systems typically operate automatically. Examples of common uses for access control systems are building entry points, mass transit facilities, and secured areas.
