A surcharge waiver is a benefit in which the additional fee on your transaction is waived off if you pay using your card at certain merchant outlets.For example, when you use your card to purchase fuel at a petrol pump, you may be charged a surcharge fee by the petrol pump operator. This fee is typically a percentage of the transaction value and is added to your bill. With a surcharge waiver, this additional amount will be waived off, saving you money on the transaction and making your purchases more affordable.
