Contactless Payment
Contactless payment lets a card, phone, or wearable exchange payment data with a compatible terminal over a short-range interface such as NFC.
Digital-wallet and mobile-payment terms for contactless credentials, stored-value balances, prepaid cards, and crypto-linked card payments.
Wallets, mobile payments, and stored-value terms describe digital credentials, prepaid balances, contactless interfaces, and app-based payment methods used at checkout or within payment platforms. This branch covers digital wallets, mobile wallets, mobile payments, contactless payment, stored-value cards, and cryptocurrency-linked cards.
Use these pages when a payment depends on a phone, wearable, tokenized card, stored-value balance, prepaid card, contactless credential, or crypto-linked account. The evidence should identify the wallet provider, funding source, token or card credential, merchant, and settlement route.

Start with what funds the payment. A wallet may store a credential, hold a balance, route through a card network, connect to a bank account, or convert from another asset before settlement. Those models create different fee, fraud, tax, and reconciliation evidence.
Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.
