Systems and methods for RFID fare collection for improving passenger throughput and security in transit systems. RFID tags identify passengers at a distance and allow a hands-free experience for transit users. The system includes gate cabinets and/or other entry points that define a passageway and separate a non-restricted access area from a restricted access area, at least one RFID transmitter positioned on the entry points, at least one RFID receiver positioned on the entry points, and a processor coupled with the RFID receiver. The system detects the presence of the RFID tag within the passageway and detects information linking to the account balance of the user. The system determines whether transit users are entering or exiting the restricted access area based on analysis of the wireless signals received by the RFID receivers, and provides an alarm signal when a transit user is not permitted to access the restricted access area.
