Why do credit cards matter?
Credit card payments are a huge market. In the US, they account for up to 40% of payments with an annual value of USD 5tn. 800m credit cards are in circulation with total debt exceeding USD 1.2 tn. The average cardholder has 3.9 credit cards and USD 6.7k debt.
In the UK, 56% of adults own credit cards and make GBP 5bn in card payments annually.
Given the interest rates and fees involved, credit cards provide high profitability and support a large industry of service providers.
What is the credit card payment journey?
The credit card payment journey, from sale to settlement, involves multiple steps and stakeholders.
Costs to cardholders include the monthly card fee and interest on borrowed amounts, while merchants pay service fees.
Although card payments occur in real-time, final settlement of cashflows is significantly later.
Who are the parties in a credit card payment?
Cardholders are consumers and corporates.
Merchants and marketplaces sell goods and services, through e-Commerce and other channels.
Payment Acquirers are regulated card payments processors who act as agents of the card issuer and schemes.
Card Issuers are banks and fintechs that market credit cards.
Card Schemes sponsor the card network, set rules, and interchange fees.
Technology providers like payment gateways connect the ecosystem with integrations to merchants and acquirers.
New models like payment orchestration emerge, where one player facilitates multiple roles to capture greater share.
What is the process of credit card payments?

- Cardholder presses pay on Merchant website.
- Data is transferred to Gateway where is it tokenised.
- Transaction is routed by Gateway to Acquirer in encrypted form.
- Acquirer sends message to the Issuer to verify.
- Issuer confirms with Card Scheme that Cardholder is legitimate (authentication) and funds are available (authorisation).
- Card Scheme passes response to Issuer and Acquirer.
- Acquirer sends success/fail message to Gateway.
- Gateway sends success/fail message to Merchant.
- Merchant website sends success/fail message to Cardholder.
- Merchant is paid in arrears by Acquirer, net of chargebacks, fees, reserve adjustments.
- Gateway charges Merchant separate fee.
Common problems in the credit card payment journey
Cardholders
Card detail error or expiry.
Fails two-factor authentication.
Insufficient limit.
Merchants
Fails PCI-DSS requirement.
Technology failure.
Payment Acquirer
Transaction declined as suspect (amount, location, currency, pattern, etc).
Transaction fails velocity check.
Stakeholders monitor performance using metrics such as conversion ratio, acceptance rate, disputes, chargebacks, losses to fraud, and technology error codes.
Risks in the credit card payment journey
Payment Fraud
Mastercard estimate global losses to eCommerce fraud total USD 50bn annually and expect this to rise as criminals embrace technology to stage phishing, identity theft, and account takeovers.
Chargebacks
Customers often dispute payments. Most are settled amicably, but instances of chargeback fraud occur when the cardholder cancels the payment with the card issuer, leaving the merchant with a loss. If a merchant has a history of chargebacks, the issuer will request a rolling reserve.
Credit Risk
Credit risk occurs when a counterparty does not settle their obligation, in full, on time. As settlement occurs in arrears there is risk in the credit card payment journey, notably between Issuer-Cardholder and Merchant-Acquirer (albeit they are usually large and regulated).
Technology Risk
Processing credit card payments requires integration of web and mobile apps, payment gateways, tokenisation, and payment acquirers. Failure of any element will result in cart abandonment or failed card payments. Each element, and the data therein, must be secured in accordance with Payment Card Industry Data Security Standard (PCI-DSS) requirements.
Summary of the credit card payment journey
Credit cards provide access to unsecured debt and are convenient for payments. Volumes are expected to grow in all major markets, making them a vital element in any payments mix.
As the credit card payment journey illustrates, the industry is complex, raising concerns about opacity, cost and settlement speed.
Innovation is creating competition and alternative payment methods, thus merchants and PSPs must retain focus while taking opportunities to optimise their partners, processes, and technologies.
