Pre-authorisation is set at $50 per vehicle and only sets aside part of your card’s credit limit for charges via EZ-Link Motoring Service. It does not reflect that an actual charge has been made to your credit card. This earmarking allows your EZ-Link Motoring Service charges to be processed when they are incurred. The actual charge will only be made when there are ERP or carpark (EPS) transactions incurred by your registered vehicle, however this is subjected to change. Any unutilised pre-authorisation amount will be released back to your account after the holding period determined by the issuing bank of the credit or debit card.
You may receive a Credit or debit Card Transaction Alert from your issuing bank on the $50 pre-authorisation, if you have changed the default threshold amount to a lower threshold amount for the Credit Card Transaction Alert to be triggered.
