01You tapped. The terminal sent an authorization request.
02The issuer approved or declined it. That was a decision—not settlement.
03This issue follows what happens after APPROVED.
The second journey of a card payment

The receipt says paid. Who has the money?

The word APPROVED ends the conversation at the counter. Behind it, the records—and then the value—still have to move.

The reveal

Approved is not settled.

The approval moved first. Next, the participants exchange and reconcile transaction records. Only after obligations are calculated does value move in settlement.

01 / After approved

The purchase begins a second journey.

This simplified four-party, dual-message model separates the records from the later movement of value.

Receipt

The fast decision is complete

The issuer approved the authorization request and the terminal recorded the answer. The sale can continue, but interbank settlement has not happened here.

APPROVED = decision returned
Present

The purchase returns as a record

The merchant side submits richer transaction information through its processor or acquirer. The amount, merchant, currency and transaction references become part of the clearing record.

“This approved purchase is ready to clear.”
Reconcile

Acquirer ↔ network ↔ issuer

The participants exchange and compare transaction records. In a specific network, identifiers can connect a clearing record to the authorization that came before it.

Calculate

Many purchases become obligations

A clearing arrangement may offset streams of transactions and calculate what each participant owes or is owed. One purchase does not necessarily create one identical bank transfer.

NET OUTowesNET INreceives
Settle

Value crosses the settlement mechanism

Settlement transfers value between issuer and acquirer to discharge the obligation. The merchant-credit or payout leg then follows the provider’s contractual arrangement.

information first → value later
Information · First

Records establish what happened

Authorization returns a decision. Clearing then carries the detailed transaction record, reconciles it, and establishes the obligations among participants.

Value · Then

Settlement discharges the obligation

Value moves between issuer and acquirer through the relevant settlement mechanism. Exact rails, timing, finality rules and merchant payout arrangements vary.

02 / Why it matters

One word at the counter hides three different states.

Separating authorization, clearing and settlement explains familiar payment mysteries.

01

Approved is not the same as posted

The authorization exists, while the final cleared transaction may still be making its way into the account ledger.

02

The merchant’s payout has its own clock

The customer can leave immediately, while merchant credit follows the acquiring provider’s contract and schedule.

03

One purchase need not equal one transfer

Where netting is used, many records can be compressed into participant positions before settlement.

Myth
“The receipt says approved, so the merchant already has my money.”
Reality
Approval returns first. Clearing establishes the records and obligations. Settlement moves the value.
The one-sentence model

First the message. Then the math. Then the money.

How we know

  1. Visa: authorization, clearing and settlement lifecycle
  2. European Central Bank: clearing, reconciliation and netting vocabulary
  3. BIS/CPMI: clearing, netting and settlement glossary
  4. Federal Reserve: issuer, acquirer and network definitions

This issue illustrates a simplified four-party, dual-message card purchase. Netting is not universal, and exact participants, records, rails, timing, finality and merchant payout arrangements vary by network, provider and market.
