Why are there duplicate verification charges?
When you add a credit card to your GunTab account, we ask your bank to “authorize” 2 small verification charges. These charges become visible in your online banking without being withdrawn. After you enter the 2 amounts into GunTab, we “void” those verification charges so they will disappear from your online banking within the next 1-2 days. Some banks represent these 2 different operations (authorize and void) separately, by showing the 2 verification charges a second time. This may be confusing, but it is common and there is nothing to worry about. These verification charges will disappear within 1-2 days.
