The process of RFID access control and its Specification

A standard RFID-based high security system includes 1) tags with unique identifying data capable of allowing or refusing entry to secured areas, and 2) a method for scanning the RFID tags at access command posts. RFID access control can be attached to items or incorporated in cardboard or plastic ID cards. They can even be lodged beneath human skin, however this is heavily debated. When the tags are read at access command posts, their data is confirmed against a database in a centralised surveillance system, and access is given or refused.


The centralized security system can not only regulate access using identifying details, but it can also be connected with other services as part of a holistic security solution. For example, an RFID security system may be programmed to automatically track the number of users and hackers per ID and to activate surveillance cameras when a certain threshold is met.

When a person attempts to enter an area where he or she does not have authority, the system identifies this and can activate video surveillance as well as transmit notifications to protection or other authoritative officials. Even if a person has clearance to enter the security perimeter, video recordings can be started to monitoring the person's behavior while within.

Regulating building access with Long range rfid reader  [A1] has a few drawbacks that should be addressed before deploying such a system. The first is that if an unauthorized individual "tailgates" an authorized person through an access point, the mechanism can be evaded. It should be highlighted, nonetheless, that this is additionally a drawback of the previously described conventional access control methods. A second problem is that the system may be thwarted: RFID tags can be copied using inexpensive technology. Someone with an RFID reader may "skim" information from an identification tag and create a new ID badge with the required access rights.
