If you've noticed a small pending charge on your card, don't worry! This is a standard procedural check to confirm that the card is active and valid.
Depending on who you bank with, it may take longer for the funds to release back to you. If you bank with NAB, this may take up to 10 business days. For other banks, the normal time frame is between 2-10 business days.
Please note: The ping is only ever a pending charge, and the money never actually leaves your account!
