A card payment looks instant: you tap, the terminal beeps and you leave. Behind that beep, money moves in several steps and through several hands. Knowing the path explains pending charges, refunds that take days, and why a card can fail even when you have enough money.
Who is involved
You
The cardholder. You agree to pay your issuer back, or you spend your own money.
Merchant
Takes the payment at the till or checkout and pays a fee for the service.
Acquirer
The merchant's bank or processor. It receives the payment request.
Card network
A company such as Visa, Mastercard or American Express that links the banks.
Issuer
The bank or company that gave you the card. It approves, declines and bills you.

Seconds
Authorization
The issuer checks your limit, balance and fraud signals, then approves or declines. Approval puts a hold on the money.
Same day or a day later
Clearing
The merchant sends the final amount, including any tip, through the acquirer and network.
1 to 3 days
Settlement
Money moves between the banks. The pending charge becomes a posted transaction.
Why this matters to you
Pending amounts can differ. Fuel pumps and hotels place a hold larger than the final bill.
Refunds start a second journey. A refund follows the same path backwards, which is why it can take days to appear.
Cross-border payments add steps. The network or the issuer converts the currency, and the rate and fee are set by them. See paying abroad.
Declines have a reason. The most common are a limit, a fraud check, a wrong detail, or a network the merchant does not accept.
Words on your statement
- Pending
- An authorized charge that has not settled yet. The amount can still change.
- Posted
- A settled charge that is now part of your balance.
- Hold
- An amount reserved on your card, for example at a hotel or fuel pump.
- Interchange
- A fee the merchant's side pays the card issuer for each sale. It is why some shops prefer cash or ask for a minimum.
If a line looks unfamiliar, check the merchant's trading name. It may differ from the shop's sign, because the name comes from the acquirer.
Questions people ask
Why is the amount on my statement different from the one I saw at the till?
Some merchants authorize one amount and settle another. Tips at restaurants, fuel pumps and hotel stays are common examples. The settled amount is the one that counts.
Who decides whether my card works abroad?
The card network carries the request, but your issuer, the bank or company that gave you the card, approves or declines it. Declines often come from fraud checks or limits, not from the country.
