If you already have a Citi Credit Card, sign up to EZ-Pay. You'll then receive an SMS from EZ-Link with 1 business day to verify your IU number. Upon successful registration you'll receive an email confirmation within 4 days with the effective start date of EZ-Pay on your Citi Credit Card.
Note: Upon registration of EZ-Pay, EZ-Link will be entitled to hold and obtain a pre-authorization on your Citi Credit Card. Pre-authorisation only sets aside part of your card’s credit limit for charges via EZ-Pay. It does not reflect an actual charge that has been made to your credit card. This earmarking allows your EZ-Pay charges to be processed when they are incurred. The actual charge will only be made when there are ERP transactions incurred by your registered vehicle. The pre-authorised amount is currently set at $50 per vehicle and will be held and refreshed by EZ-Link every 5 days, or upon the utilization of 50% of the pre-authorised amount, to be applied towards the payment of EZ-Pay services, 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 card.
For customers who are on Citi Alerts and have set their Credit Card Transaction Alert amount to SGD50 or less, you will receive notifications on these pre-authorizations. Please note that these Citi Alerts will state "There was a charge of SGD50.00 on your Citibank Card ending XXXX by EZ-LINK PTE LTD SINGAPORE.".
