The $1/£1/€1 authorization is a temporary card check that occurs when you enter your payment details at checkout to publish your Stamp Card.
Verifying cards with a hold before a subscription begins is a common industry practice.
The card check confirms two things:
That your credit or debit card is valid
That funds are available to ensure a seamless transition to a paid plan after your free trial
If your card has insufficient funds, the checkout process will fail.
How it Appears on Your Bank Statement
The $1/£1/€1 will remain in a pending status on your statement for 5-7 days, depending on your bank. No funds are deducted - it’s simply a temporary hold.
An example of the pending transaction is highlighted below.
When and How the Hold is Removed
The authorisation is automatically cancelled after 7 days. No further action is required on your part.
Once the hold is released, it may be removed from your transaction history or appear as a cancelled or voided transaction, depending on your bank.
An example of the cancelled transaction is highlighted below.
