The new Cardtonic platform requires that you set a pin that you can use to authorize your withdrawals.

Proceed to the "Settings page" and click on "Security."

Choose "Authentication."

Then click on "Set Pin."

Then, enter your 4-digit pin.

Once your pin is set, whenever you want to withdraw, you will be required to use this pin to authorise the withdrawal

You can always reset your pin if you forget it.
