Ever wondered what happens when you tap your card?

Here’s a breakdown of the process:

For example, buying yourself a coffee with your card,

  1. Authorisation:

    → You tap your phone or card: Merchant’s (the Acquirer) POS [Point of Sale] system captures the transaction.

    → Payment gateway encrypts and routes it.

    → Card Networks (Visa, Amex, Mastercard) checks with your bank (the Issuer).

    → Your bank (Issuer) accepts or rejects immediately.

  2. Clearing

    → The Merchant’s bank and your bank exchange the transaction information.

  3. Settlement

    Issuer sends funds to Acquirer, minus transaction fees.

    Merchant receives the payment.

All of this happens in ~2–3 seconds for the customer experience!

Key Players:

  • Issuer (Your bank): Approves transaction and sends funds.

  • Acquirer (Merchant’s bank): Receives funds for merchant.

  • Payment Processor/Gateway: Middleman that moves data securely (Stripe, PayPal, Adyen).

  • Card Network: Facilitates communication and rules (Visa, Mastercard, Amex).


Payment transactions have evolved tremendously over the past few decades, moving from simple cash exchanges to highly sophisticated digital processes that complete in just a few seconds. Today, multiple players—including banks, card networks, and payment processors—work seamlessly behind the scenes to ensure fast, secure, and reliable transactions. The industry continues to evolve rapidly, embracing innovations like contactless payments, mobile wallets, and real-time settlement, shaping a future where payments are faster, smarter, and more convenient than ever.

Here are the main pillars of the payment industry:

  1. Issuers – Banks or financial institutions that provide cards or accounts to consumers.

  2. Acquirers – Banks or institutions that manage merchant accounts and receive payments on behalf of merchants.

  3. Payment Processors / Gateways – Companies that securely transmit payment information between merchants, banks, and networks (e.g., Stripe, PayPal, Adyen).

  4. Card Networks – Organizations that facilitate transactions and set rules for card-based payments (e.g., Visa, Mastercard, Amex).

  5. Merchants / Businesses – The sellers accepting payments for goods and services.

  6. Regulators & Compliance – Authorities and standards ensuring security, transparency, and legal compliance (e.g., PCI DSS, central banks).

  7. Consumers – End users who initiate transactions using cards, wallets, or other payment methods.

The payments industry can be divided into several key categories, each focusing on a different aspect of the ecosystem:

  1. Card Payments – Debit, credit, and prepaid card transactions processed via card networks (Visa, Mastercard, Amex).

  2. Digital Wallets & Mobile Payments – Mobile apps and wallets that store card or bank info for contactless and online payments (e.g., Apple Pay, Google Wallet, PayPal).

  3. Bank Transfers / ACH / EFT – Direct bank-to-bank transfers for bill payments, payroll, or e-commerce settlements.

  4. Buy Now, Pay Later (BNPL) – Financing solutions allowing consumers to split purchases into installments (e.g., Klarna, Afterpay).

  5. Point of Sale (POS) Systems – Hardware and software solutions enabling in-store payments and transaction management.

  6. Payment Gateways & Processors – Technology intermediaries that securely transmit transaction data between merchants, banks, and networks.

  7. Cryptocurrency & Blockchain Payments – Digital asset-based payments and settlements using blockchain technology.

  8. Cross-Border / Remittance Payments – International payments and money transfers between countries.

  9. Fraud Detection & Security Solutions – Services that monitor, prevent, and manage payment fraud and cyber threats.

It’s easy to think buying a simple cup of coffee is instantaneous, but behind that quick tap of your card lies a complex web of processes—and a host of companies working together seamlessly. From your bank approving the payment, to the card network routing it, to the payment processor ensuring security, and finally the merchant receiving the funds, each transaction is a miniature feat of coordination and technology. What feels like a two-second action is actually the result of a highly advanced ecosystem running in perfect harmony.
