Quasi cash transactions are treated as cash advances hence cash advance fees will be charged and interest begins to accrue once your card has been charged.
Cash advance charges are at 6% of the amount withdrawn/transaction amount incurred, or S$15, whichever is greater. Interest charges will also be levied at the prevailing cash advance interest rate (28% pa) on the amount withdrawn/transaction amount incurred from the date of the transaction until the date repayment is made in full, or the next statement date, whichever is earlier.
