Why have I been charged $1 when signing up or adding a new card?
If you've noticed a $1 pending charge on your newly added card and bank with NAB (National Australia Bank), then, unfortunately, this is just a procedural check to confirm that the card is active and valid.
This $1 pending charge will never process fully, and should be returned to your account within 2-3 business days.
We are really sorry for the inconvenience!
Important: this $1 is really not a charge, and it will disappear from your statement eventually.
