When you create an account with SUBTYPE and save your payment details, an authorisation charge of $0 or $1 will be charged. This is a common practice by banking gateways to verify cards. Please know that this charge will be automatically voided.
The $1 transaction you see on your credit card statement is not a charge, just a temporary hold on funds. It is not debited into the SUBTYPE account and SUBTYPE cannot access this money.
For most financial institutions, a $0 authorisation will first be tried. If this authorisation is not supported, a $1 authorisation will automatically be performed.
In any instance where a $1 authorization returns a successful result, our payment gateway immediately follows up with an automatic void request to cancel the transaction. This is to ensure the transaction does not settle and that it disappears from your statement as soon as possible.
If you find that the charge does not void, please contact your financial institution.
