What is an access control badge?

Access control badges are security credentials, often in the form of cards or key fobs, that are used to grant or restrict physical access to secure areas within a building or facility. These badges typically use technologies such as RFID, magnetic strips, or smart chips to authenticate the holder’s identity. By swiping, tapping, or inserting the badge at a reader, authorized personnel can enter designated zones while unauthorized individuals are denied access. Access control badges help organizations manage security, monitor entry and exit, and ensure only approved individuals can reach sensitive locations.
