Who makes the Norpass/Prepass transponders?

Trying to figure out what the company is that makes those tags used by Prepass and NorPass.

Anyone got a transponder, maybe a broken one or can look where you replace the battery and can tell me the company name of the manufacturer?

I work as a programmer for quarries/asphalt plants, for the life of us we cant figure out who makes those tags, I do know that it is transcore who makes the toll tags, but they dont have bells and whistles like the norpass transponders do.

 

Nevermind found this ...thanks all..

The standard transponder, which works in any system, is a Raytheon-Delco Type II+.

 

thank you so much
