Once you provide us with your credit card details, we will send over a request to your bank for a $1 authorisation to verify that the card is issued, valid and the bank will allow it to be authorised. We reverse this authorisation request immediately.
However, some people may still see an authorisation for $1 on their credit card statement. The important thing to remember is that this is not a charge, and it will disappear from your statement. Depending on the bank, it will be removed from your statement in anywhere from a few minutes to a few weeks.
