TxTag (pronounced "textag"[1]), operated by the Texas Department of Transportation (TxDOT), is one of three interoperable electronic toll collection systems in Texas.

Current system status[edit]

The TxTag brand name is used on the following highways:


Since 2003, HCTRA's EZ TAG and NTTA's TollTag have been mostly interoperable, with the exception of Dallas/Fort Worth International Airport and Dallas Love Field airport parking, where NTTA's TollTag is the only ETC system recognized. TxTag transponders are accepted at all designated lanes on HCTRA and NTTA roadways. EZ TAG and TollTag are accepted at any TxTag locations.

TxTag transponders are currently not accepted:


TxTag uses at least two types of transponders manufactured by TransCore: legacy hard case AT5100 transponders and newer eGo Plus flexible sticker-type transponders. The transponders are mounted on the inside of the vehicle at the top center of the windshield. The TxTag sticker can be used as a portable device, provided it is affixed to a small square of glass instead of a windshield. According to the patent for the device[citation needed], the sticker was specifically designed such that if removed, among other things capacitor 66 is decoupled from 64, preventing the use of the sticker if it is torn from the glass. It would also appear the sticker can be simply taped to the inside of the windshield for temporary use.
