Any of the options will work for the Cashless Debit Card. To make a purchase at a point-of-sale terminal, insert your Cashless Debit Card into the device and press “SAV” or “Savings” or “CHQ” or “Cheque” or “CR” or “Credit”. Then follow the prompts to enter your PIN.
If you have contactless payments turned on, you can pay by tapping your card on a payWave enabled terminal and waiting for the transaction to be confirmed. There is no need to enter a PIN for purchases of $100 or less (or $200 or less at some businesses).
