Access control is a critical tool for security and accurate time and attendance calculations, but traditional proximity cards require manual presentation to a reader in order to work.

Not only is this approach is too slow for many enterprise operations which require high volume, high speed entrance and exit management, but it also is error-prone, as people can follow others through a door without credential presentation.

Active RFID can be used to create an access control system or used to improve an existing, proximity card system.

Active RFID-based solutions uses a card or fob, which when carried on a person is automatically read, providing “hands-free” high speed access, eliminating the need to manually swipe cards or punch a keypad.

In addition to automatic identification, the system can know which direction the person is moving and whether the person is in or out of the facility.

The automatic collection of this data enables interface with or reconciliation with time and attendance systems and can provide critical information in the event of emergency situations or evacuations.
