Add any card and earn full reward points
If you pay a bill with a credit card using the Sniip app and it's attached to a loyalty program, you will earn the full amount of points - in the same way that you earn points for making a purchase. This includes payments made to the ATO.
The processing fee for credit cards including Amex is 1.5% (inc GST).
Debit cards are completely free to use with the Sniip app.
