There are a number of reasons why your tag may have stopped lifting the barrier at toll booths. Toll booth operators commonly suggest that the tag is faulty/out of battery, but this is very rarely the case.
Tag Positioning
The main offender. Ensure that your tag is positioned correctly. It should be fixed to the black dotted area at the top of the windscreen. Windscreens vary widely so you should consult your car manual for the section on radio equipment.
Insufficient Credit
If your tag is out of credit, it will not lift the barrier. It is important to note that when you top up, it takes up to six hours for the tag to become operational on some roads. (Sometimes it takes longer, but it’s rare).
If you have an automatic top up and your balance is too low to lift a barrier, it indicates an issue with the debit/credit card on the account. If you received a new card recently, you will need to update the details on your account online or by calling our support team.
