June 4, 2014 – Engineering.com offers a quick overview of RFID for access control, ensuring people and vehicles are only where they need to be, and when.
There are a number of applications for RFID being developed for access control. The fastest growing are for personnel access, gate control, and parking facilities. Here’s a brief look at each of these applications.
In its most common form, RFID access for personnel may simply be the inclusion of an RFID tag in the identification badge of the worker. RFID has made inroads into this area that was originally dominated by the magnetic stripe badge. RFID applications for personnel access typically uses low frequency, 135 KHz, systems for the badge detection.
RFID badges can be used to control access to particular areas, for time keeping, or other applications. For example, there are two popular medical applications that move into the higher frequency domain where the application is used to determine the location of either medical staff or wandering patients.

In areas or businesses that have other applications for the use of RFID, parking facilities may be able to take advantage of the RFID infrastructure to improve customer service. Airport administrators, for example, have found that when implementing RFID for curb space tracking and control, the application may be extended into their parking facilities through the installation of card readers at the entrance and exit points. Such implementation provides the customer faster ingress and egress from the facility.
Even when the parking facility is not associated with a business such as an airport, the investment for tags can be a worthwhile investment to improve customer satisfaction.
