Cards & Merchant Payments / Learning brief
Card clearing and settlement, explained
Your notes
In simple terms / 01
What this means in plain language
How an approved card payment becomes money: end-of-day batches, clearing records presented through the network, interchange applied, multilateral net positions, one settlement movement between banks, and the final postings that debit the cardholder and pay the merchant net of fees.
Authorisation only promises; clearing and settlement deliver. Clearing is the information stage: the acquirer presents each captured transaction as a clearing record into the network, which validates the records, applies the interchange fee due from acquirer to issuer, and calculates one net position per member bank. Settlement is the value stage: the netted amounts move across settlement accounts between the banks, once per cycle. After settlement, the issuer posts the final debit that replaces the cardholder's authorisation hold, and the acquirer credits the merchant its takings minus the merchant discount. Exact timing — often within a business day or two end to end — depends on each scheme's cycles and cut-offs, not on a universal rule.
Key takeaways / 03
Three things to remember
- 01
Clearing moves records and arithmetic — validation, interchange, net positions; settlement is the only stage where money moves between banks.
- 02
Netting collapses a cycle's transactions into one payable or receivable per bank, shrinking liquidity needs and the number of value movements.
- 03
The cardholder's hold becomes a booked debit and the merchant is paid net of fees only after settlement; the timing is scheme-dependent.
Practical use cases / 04
Where you would use this
Reconciling a merchant's gross card takings against the net batch credit and the fee lines on the acquirer statement.
Explaining why a cancelled purchase shows as a pending hold that disappears, rather than a debit followed by a credit.
Investigating a rejected clearing record — repairing and re-presenting it within the scheme's window before late-presentment dispute rights arise.
Worked example / 05
Put the idea into a real situation
Illustrative example (SYNTHETIC / TRAINING ONLY): at close of business, Demo Coffee Ltd's batch — including Maya Chen's EUR 3.80 flat white — goes to Meridian Bank, which presents clearing records into Cardnet, a fictional card network standing in for Visa- or Mastercard-style networks. Cardnet validates the records, applies interchange (at an illustrative 0.2%, the EUR 3.80 coffee carries a fee that rounds to EUR 0.01), and nets each member bank's day into a single pay-or-receive figure. After the settlement bank moves the net amounts, Bank Alfa posts the EUR 3.80 debit that replaces Maya's hold, and Meridian credits Demo Coffee the day's takings less its merchant discount. One coffee, two postings — and exactly one inter-bank value movement, shared with every other transaction in the cycle.
Operational sequence / 06
Follow the message and decision path
This compact sequence is a learning model. Exact routing and rulebook behavior can vary by scheme, participant, and implementation.
Read the steps as text
- 01MessageDemo Coffee closes the day's batchDemo Coffee Ltd (merchant) → Meridian Bank (acquirer) · end-of-day capture batch
At end of day the terminal sends its captured sales — each with its authorisation code — to Meridian Bank. Until this capture, Maya's EUR 42.50 exists only as an approval and a hold.
- 02MessageMeridian Bank submits clearing records to CardnetMeridian Bank (acquirer) → Cardnet (card network) · clearing record
The acquirer turns each captured sale into a clearing record and presents it to the network — the presentment. Each record references its authorisation so the issuer can match it to the hold it placed.
- 03Clearing obligationCardnet runs the clearing cycle and applies interchangeCardnet (card network)
The network validates each record and attaches interchange — the fee the acquirer pays the issuer on each transaction, set under the scheme's rules. The record now says exactly who owes whom, and how much of it is fee.
Clearing establishes obligations, interchange included. No money has moved yet — that is settlement's job.
- 04Clearing obligationCardnet calculates each bank's net positionCardnet (card network)
Across the day's records, everything each bank owes and is owed collapses into one net figure per participant — multilateral netting. Bank Alfa owes the net of what its cardholders spent; Meridian Bank is owed the net of what its merchants sold.
A net position is still an obligation, not money.
- 05SettlementNet amounts move between settlement accountsBank Alfa (issuer) → Meridian Bank (acquirer)
The scheme's settlement bank moves each participant's net amount. On this transaction Bank Alfa settles EUR 42.40 to Meridian Bank — the EUR 42.50 sale less the illustrative EUR 0.10 interchange the issuer retains — inside Bank Alfa's larger net payment. This is the moment money actually moves between the banks, typically a day or two after the sale, on a timetable each scheme's rules set.
- DR Bank Alfa settlement account — EUR 42.40
- CR Meridian Bank settlement account — EUR 42.40
- 06PostingBank Alfa posts the final debit and releases the holdBank Alfa (issuer)
The cleared record replaces the authorisation hold: the reserve is released and a posted debit takes its place. Only now has Maya's money actually left her account — the 'pending' line on her app becomes a booked transaction.
- RELEASE Maya Chen's card account at Bank Alfa — EUR 42.50
- DR Maya Chen's card account at Bank Alfa — EUR 42.50
- 07PostingMeridian Bank pays Demo Coffee, less the merchant discountMeridian Bank (acquirer)
The acquirer credits Demo Coffee EUR 41.90 — the sale less the merchant discount, the acquirer's charge that covers interchange, scheme fees and its own margin. The figures are illustrative; the actual rate comes from Demo Coffee's acquiring agreement.
- CR Demo Coffee Ltd settlement account at Meridian Bank — EUR 41.90
- 08MessageThe purchase lands on statementsBank Alfa (issuer) → Maya Chen (cardholder)
Maya's card statement shows Demo Coffee Ltd, EUR 42.50, now booked. Demo Coffee's acquiring statement shows the payout and the fees taken. Both sides can reconcile the same sale from their own end.
Evidence & review / 07
Evidence & review
Dual-message card systems on four-party schemes; clearing cycles, cut-offs, and settlement timing are set by each scheme's rules and membership agreements.
What this brief simplifies: One clearing cycle, one currency, and a single-transaction ledger view stand in for bulk multilateral reality; single-message debit systems and currency conversion are out of scope.
