How to enable surcharging on your EFTPOS terminal 

Only users with the manager passcode can enable surcharging. 

You can find your monthly Cost of Acceptance information on your first merchant statement. For the period where Cost of Acceptance isn't available, you can choose not to surcharge or to surcharge at a rate that is no higher than what it costs you to process a transaction.

You should only have to review the level of surcharge once a year using your annual Cost of Acceptance information. If this isn’t available (because you’re a new merchant, your business is seasonal, or your transactions change from month to month), you can change your surcharge limit on a monthly basis using your monthly statements.

Your Cost of Acceptance is shown as N/A when there isn’t enough information to calculate your Cost of Acceptance. This may occur if you’re a new merchant or your facility has been inactive for some time.

Yes, but you must set the surcharge at the level of the lowest Cost of Acceptance across all card types. Surcharging rules don't allow you to surcharge an average of the percentages shown under the (%) of net sales column.

The regulations don't prevent you from imposing a payment surcharge as a fixed fee, but it may be easier for you to apply a surcharge as a percentage because in most cases payment costs are charged in percentage terms.

When surcharging with a fixed fee, make sure the amount of the surcharge doesn't exceed your Cost of Acceptance for any given transaction. You should also be careful when imposing a flat fee surcharge where the cost of a transaction is relatively small, as the surcharge is likely to be excessive.

You'll need to work with your POS provider to enable surcharging on your POS.
