the facility. Which of the following controls will allow the organization to provide automated

Explanation:
RFID is radio frequency identification that works with readers that work with 13.56 MHz smart
cards and 125 kHz proximity cards and can open turnstiles, gates, and any other physical security
safeguards once the signal is read. Fitting out the equipment with RFID will allow you to provide
automated notification of item removal in the event of any of the equipped items is taken off the
premises.
