You tap a card. The terminal pauses, then shows Approved.
The customer takes the purchase. The merchant prints a receipt. The moment feels complete.
But approval did not pay the merchant.
It answered a narrower question: will the card issuer authorize this transaction under the information available now?
The issuer can check the account, available credit or funds, fraud signals, card status, and transaction details. An approval tells the merchant that the transaction may proceed. It may also reduce what the cardholder can spend by placing a hold or reserving capacity.
No money has reached the merchant’s bank account yet.
The next step is capture. The merchant confirms the amount it intends to collect. Sometimes capture follows immediately. Sometimes it waits until an order ships. Restaurants, hotels, and car-rental companies may begin with an estimated authorization and later submit a different final amount.
That difference matters because authorization and clearing must eventually meet. Visa’s processing guidance explicitly treats an approved authorization with no matching clearing record—or a clearing record with no matching authorization—as a transaction-integrity problem.
After capture, the transaction enters clearing. The merchant’s acquirer submits the financial record through the card network. The issuer posts the transaction to the cardholder’s account. Settlement resolves the obligation between participating institutions, and the merchant is funded according to its arrangement with the acquirer or payment provider, usually after fees and any other adjustments.
One tap has therefore created several distinct events:
- the issuer approved the purchase;
- the merchant completed or captured it;
- the transaction was cleared through the network;
- institutions settled what they owed;
- the acquirer or provider funded the merchant.
They often happen smoothly enough to feel like one event. Production systems cannot afford to store them as one event.
An authorization can expire or be reversed without capture. A captured amount can differ from the original estimate. A processor can accept a transaction while the related merchant payout is still pending. A refund or dispute can change the economics after funding.
This is why the word paid needs an owner.
To the customer at the terminal, it may mean the issuer approved the purchase. To the merchant’s order system, it may mean capture succeeded. To treasury, it may mean the payout reached the bank. Each answer can be true at a different boundary.
The terminal says Approved because that is the answer needed to finish the interaction at the counter.
The financial system keeps working after the customer walks away.
