Keycard systems are widely recognized as a common type of access control used in security. These systems utilize magnetic or electronic cards that grant access to authorized individuals when presented to a card reader. The convenience and efficiency of keycard systems make them a popular choice for various settings, including office buildings, hotels, and secure facilities.

One of the main advantages of keycard systems is their ability to easily manage access. Administrators can issue and revoke cards quickly, allowing for streamlined security measures in response to personnel changes. Additionally, keycard systems often allow for tracking and logging of entry and exit times, which can be valuable for both security and operational purposes.

While fingerprint scanners, facial recognition software, and metal detectors are also types of access control, they serve different functions or are used in more specialized contexts. For example, fingerprint scanners and facial recognition systems provide biometric authentication, which may not be as broadly implemented as keycard systems due to cost or technological requirements. Metal detectors are primarily used for searching individuals for weapons or contraband rather than controlling access to specific areas.
