Berkeley’s Detect-A-Pass™ is an E-ZPass detector that discovers hidden E-ZPass transponders that could be used for vehicle tracking and other privacy and security violations. Educate and inform yourself with this simple E-ZPass detector. Whether you’re a privacy advocate, concerned commuter or a champion for security, Berkeley’s Detect-A-Pass delivers realtime polling status from all 915 MHz ISM D.O.T. commuter traffic, tolls & tracking systems including E-ZPass®, Express E-ZPass®, Smart Tag®, I-Pass®, I-Zoom®. M-Tag® and Quick Pass®. Simply place the device on your dashboard or near your vehicle’s tag and it will alert you anytime your tag is being polled by any D.O.T. RFID readers stationed at any toll booth, intersection, highway and elsewhere. Detect-A-Pass provides drivers with instant visual and audible warnings when their transponder or vehicle tag is transmitting. This provides a confirmation that the toll booth successfully communicated with their vehicle’s transponder.
Outside of the toll area, you will receive alerts if any transponder is communicating unbeknownst to the operator. For instance, many unmarked D.O.T. RFID systems monitor and report traffic flow regularly on many roads and highways. Detect-A-Pass is a secure, passive ‘receive-only’ monitoring detection system and thus does NOT transmit any information or communicate directly with any RF transponders. It only detects when your vehicle tag is being polled. Detect-A-Pass was designed with your security and privacy in mind.
