When you pay with a card, not every charge immediately takes your money. Sometimes, the merchant first reserves the amount on your card before completing the payment. This is called card pre-authorization.”
What is a card pre-authorization?
A card pre-authorization is a temporary authorization that allows a merchant to verify that your card is valid and that sufficient funds (or credit) are available before completing a transaction.
Instead of immediately capturing the money, the card issuer sets aside the amount, making it unavailable for you to spend elsewhere.
The merchant can later:
- Capture the authorized amount.
- Capture a smaller amount.
- Cancel the authorization.
- Let the authorization expire.
Why do merchants use pre-authorizations?
Pre-authorizations are useful when the final amount isn’t known at the time of payment.
Common examples include:
- Hotels (for room charges and incidentals)
- Car rentals
- Fuel stations
- Restaurants (before adding tips)
- Online subscriptions with free trials
- Food delivery platforms
- Ride-hailing services
- E-commerce merchants verifying your card
A card pre-authorization is not a completed payment. It’s a temporary hold that confirms funds are available before a merchant finalizes a transaction. Once the merchant captures the authorization, the payment is completed. If they don’t, the hold expires and your funds become available again.
