Hand readers for access control are electronic components that are used to sound an alarm when someone attempts to gain unauthorized access to a secured area. They are often used in conjunction with an access control system to restrict access to secured areas to only authorized individuals.

Hand readers for access control are small electronic devices that are installed at the entrance of a building, office, parking garage, or other secured area. They are connected to the access control system and send a signal to the system when someone attempts to gain unauthorized access. This can trigger the alarm to be activated, or the door to be locked or unlocked, depending on the settings of the system.

Hand readers for access control are effective at restricting access to secured areas because they are difficult to bypass. They are also an effective way to record who has access to certain spaces and when, which can help with compliance with laws and regulations, reducing theft, and improving overall security.
