3. Common payment types and how they work

• Cash: physical currency; instant, anonymous, no intermediaries, final settlement on handover.
• Debit cards: bearer-linked to a bank account; authorization and settlement via card networks and ACH or card-settlement rails.
• Credit cards: issuer extends short-term credit; card network routes authorization; merchant receives settlement after fees.
• Bank transfers (ACH, wire): account-to-account transfers—ACH for batch, lower-cost; wires for high-value/real-time.
• Real-time payment rails: instant push/pull transfers (e.g., RTP, Faster Payments); immediate finality.
• Mobile wallets & NFC payments: tokenized card or account credentials stored on device; tap-to-pay or in-app.
• Peer-to-peer (P2P) apps: app-mediated transfers between individuals; often settle via linked bank accounts or internal ledger.
• Automated Clearing & Card-on-file / Recurring payments: stored credentials or mandates for subscription billing.
• Cryptocurrency / blockchain transfers: decentralized ledger transfers; finality and speed vary by network and design.

Payments serve multiple functions beyond simple exchange. They act as a record of transactions for accounting and taxation, a mechanism for enforcing contracts, and a tool for monetary policy implementation by central banks. The structure of payment systems affects economic behavior: transaction costs influence market participation, settlement speed impacts liquidity, and the availability of credit shapes consumption and investment decisions.
