In an EAC system, what is a "reader"?

A "reader" in an Electronic Access Control (EAC) system is specifically designed to read and verify user identities, typically through credentials such as key cards, biometric data, or mobile devices. This device functions as the critical interface between the access control system and the individual seeking entry. By scanning or interpreting a user's credential, the reader communicates with the system to ensure that the person is authorized to access a particular area based on their permissions.

Understanding the role of the reader is fundamental to the operation of an EAC system, as it not only serves to authenticate identities but also helps to log entry and exit activities, contributing to overall security management. The reader is therefore an essential component that enables secure and controlled access in various environments, from corporate offices to secure facilities.
