Like many other services, InterNations uses an authorization hold to confirm that your credit card is active and has the funds available to purchase Albatross Membership. For example, in the United States, you might see a 1.00 USD authorization hold. If you live in another country or region, you might see a different amount in the currency of your location. Authorization holds are removed by your card issuer after a short time. The exact time it takes to remove authorization requests varies by financial institution.
If you have questions about the way your card handles authorization requests, contact your financial institution.
