With Quick Payment, your saved debit card (“bank 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 bank 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.
To enable quick payment you are to successfully complete the Account Verification (eKYC) process.
