One of the primary differences between transponders and cellular-based weigh station bypass applications is how signals are transmitted between weigh stations and trucks.
Weigh station bypass apps use CMRS (commercial mobile radio services) technology. They provide the convenience of bypassing without the use of a transponder and may be integrated within telematics or ELD technology already used in the truck. Bypass apps also provide access to a wider range of enforcement locations and provide additional functionality including PrePass ALERTS™.
PrePass transponders transmit and receive signals using RFID (radio frequency identification) technology. The transmission is 100% accurate within milliseconds. Transponders also provide access to other third party weigh station locations including Weigh2GoBC, NORPASS and Oregon Green Light. In addition, you can use the same transponder for both electronic toll payment and bypass services.
