When you pay with a debit or credit card at the pump with an OPT, the transaction is authorised by sending a pre-authorisation amount on the payment card to your card issuer.
The same applies in the Shell shop, whereby all indoor fuels purchases using a debit or credit card will be pre-authorised similar to the OPTs.
- The default pre-authorisation amount for card transactions at the OPT is RM200 for Visa or Mastercard and RM250 for Amex, but you may also select a custom pre-authorisation amount by clicking "Select Amount" on the OPT home screen.
- The pre-authorised amount for indoor fuels purchases is the requested amount i.e. when you purchase RM50 worth of fuel, the pre-authorised amount is RM50.
Once the fuel transaction is completed, the bank will receive a notification on the final amount payable, and any untilised amount from the pre-authorisation sum will be credited back into your account by your bank within 5 working days.
