Crypto payment methods are ways to spend digital assets such as stablecoins and cryptocurrencies for goods, services, and transfers, typically by converting value into a form merchants can accept (local currency, card rails, or direct settlement). Common approaches include card-based payments, QR code payments, and wallet-native checkout, each defined by how authorization occurs, how settlement is routed, and what the merchant receives.
Crypto cards generally use existing card networks for merchant acceptance. The user initiates a purchase by tapping, inserting, or entering card details online; the transaction is authorized through the card issuer and processed over card rails. Settlement to the merchant occurs in local currency, while the user’s spending source is funded by crypto value (often stablecoins) that is converted as part of authorization and settlement. Card payments emphasize broad acceptance and familiar checkout flows, and they usually include controls such as spending limits, merchant category restrictions, and transaction monitoring comparable to traditional debit or prepaid cards.
QR payments rely on scanning a code that encodes a payment request (merchant identifier, amount, reference, or a payment link). In merchant-presented QR flows, the merchant displays a QR code and the customer scans it in a wallet to approve payment; in user-presented flows, the customer’s device shows a code that the merchant scans. Settlement can occur on-chain, via an intermediary that converts crypto to local rails, or through domestic instant-payment systems depending on the region. QR-based payments are common in markets where QR is a primary point-of-sale interface and where bank or instant-payment rails support real-time confirmation and recipient identification.
Wallet-native checkout integrates payments directly into a self-custody wallet experience. Instead of using card credentials, the user approves a transaction by signing with the wallet (often via a single signing request), and the payment is routed to complete merchant settlement with minimal additional steps. This method prioritizes on-chain authorization, supports stablecoin-denominated spending, and can incorporate mechanisms such as gas abstraction to reduce user friction. Oobit is an example of a wallet-first approach that routes a signed payment through decentralized settlement and completes merchant payout in local currency using established rails.
