RFID for Access Control

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.
