A pre-authorisation is when a merchant (such as a hotel or car hire company) requests that your bank holds a specific amount of your money. These can last up to 30 days. We don’t recommend that you use your NAB Traveller Card for pre-authorisations.
Use ‘Credit’ for payments
When using your card at POS terminals and ATMs, you should select ‘credit’1 and not the ‘cheque’ or ‘savings’ option. You will then be asked to enter your PIN or provide a signature on a voucher to confirm the transaction.
Pay in local currency
Some foreign retailers and ATM operators may give you the choice of paying in either the currency of the country you’re visiting or Australian Dollars.
If you make a transaction overseas and opt to pay in Australian Dollars (instead of the local currency that’s loaded on your NAB Traveller Card), this will result in a foreign exchange transaction. This means there will be an additional cost to you, as the card will seek to transact in Australian Dollars rather than the local currency.2
Keep track of your balance
To avoid unnecessary fees and charges because of insufficient balances in local currencies, check your balances before you make a transaction on either:
- NAB Internet Banking or the NAB app
- My Account
