The Severn TAG was a payment system for collecting bridge tolls for drivers using either the Severn Bridge Crossing or the Second Severn Crossing over the Severn Estuary between England and Wales. The system was made by Amtech but was replaced in 2008 by a new system made by CS Eng. To use the system, drivers must place the Tag transponder on their windscreen to identify their vehicle as they drive through the toll lane. Lanes through the toll booths are dedicated as either Tag (unstaffed), cash (staffed) or automatic debit/credit card only. Severn TAG types There are three types of Severn TAG Season tag: allows the user to purchase a set period of time in which you can cross an unlimited number of times, the tag may only be used on one vehicle and is not transferable between vehicles. A saving can be made if the user makes more than 17 journeys per month in a class 1 vehicle (car). There are different levels of payment for different classes of vehicle. Trip Tag: a pay-per-journey tag. Credit is added to an account each month by Direct Debit, cheque, BACS, or Online via the Severn Bridge website. When the user passes through the toll, the amount of the toll is deducted from the account. An indication at each toll lane informs the user that their account credit is low. If there is no money in the account then the Tag is declined and the user must have to pay with cash. The trip tag is transferable between vehicles of the same class. Car Pool or Shared Tag: allows between two and five cars to share one tag account. The users are able to obtain one tag and then use it amongst themselves to share the toll, the price of that tag is the same as a season tag however, it can be used on up to five vehicles, and can be temporarily moved to another vehicle within the same class. The tag can only be used by one vehicle in any 24 hour period, but that vehicle can pass as many times as it chooses. All types of Tag require a £30 Deposit. If the tag is lost or stolen, a replacement is issued after payment of another £30 deposit. Limitations and drawbacks The Season TAG can only be used with one registered vehicle, this prevents misuse, however it complicates
