With Quick Payment, your saved credit, debit or prepaid card will be used to automatically reload your eWallet and pay with the exact amount needed to complete a purchase if your eWallet does not have enough balance for it.
For instance, if you buy an ice-cream that costs RM8, but you only have RM6 in your eWallet, your saved payment card will be used to automatically reload your eWallet with RM8 so you can pay for your purchase seamlessly. You will still have the RM6 initial balance in your eWallet.
Note: Quick Payment is currently unavailable for accounts registered using non-Malaysian phone numbers.
