Stablecoin cards for real-world payments.

A stablecoin card is a payment card funded by stablecoin balances such as USDC. When the card is used, the stablecoin balance is automatically converted through crypto-to-fiat conversion, allowing the payment to be processed through standard card networks. This enables businesses to offer stablecoin-backed cards that work anywhere traditional card payments are accepted. Stablecoin cards help bridge blockchain settlement and traditional payments infrastructure, making stablecoins usable in everyday commerce. Stablecoin cards are also commonly referred to as stablecoin-linked cards, particularly by card networks like Visa and Mastercard, or as stablecoin-powered cards in some industry contexts.

Many types of businesses can launch a stablecoin card program, including crypto platforms, fintech companies, and marketplaces. These programs can support a wide range of use cases such as vendor payments, corporate expense management, employee travel, SaaS subscriptions, and platform payouts. Through white-label deployment and card integration, businesses can embed stablecoin-backed cards directly into their products. This allows companies to offer modern payment capabilities while benefiting from instant settlement, programmable payments, and global card network compatibility.

Yes. Nium's stablecoin card infrastructure is compliance-ready and built on the same regulated payments infrastructure that powers our global card programs today. Nium operates under banking standards and financial regulation, with licenses and authorizations across 40+ markets. Stablecoin card programs are designed to support regulated stablecoin usage, with built-in KYC/AML controls, OFAC screening, and compliance processes aligned with enterprise requirements. This ensures businesses can launch a stablecoin-backed card program that combines blockchain settlement innovation with the security and trust expected from traditional payments infrastructure.

Today, converting stablecoins to spendable funds often requires multiple steps — sending assets to an exchange, converting to fiat, and waiting for bank transfers. This creates stablecoin spending friction and limits liquidity for businesses and users who want to use stablecoins in everyday commerce. A stablecoin card removes that friction by enabling instant crypto-to-fiat conversion at the point of payment. Instead of off-ramping funds manually, the stablecoin balance is converted automatically when the card is used. This enables instant settlement and easier liquidity management, turning stablecoins into funds that can be spent anywhere cards are accepted.

No. Merchants do not need to accept cryptocurrency to accept stablecoin card payments. When a customer uses a stablecoin-backed card, Nium performs the crypto-to-fiat conversion behind the scenes. The payment is then processed through traditional card networks such as Visa or Mastercard. From the merchant's perspective, the transaction looks exactly like any other card payment through their POS or payment network, so existing merchant acceptance infrastructure continues to work as normal.

Nium is building infrastructure designed to help businesses launch a stablecoin card program instantly and securely. Our platform supports white-label card deployment and card integration through a single API, allowing businesses to embed a stablecoin-backed card into their existing products without building their own issuing infrastructure. While the exact timeline depends on integration and compliance requirements, Nium's goal is to make stablecoin card program deployment significantly faster than building card infrastructure from scratch.

Yes. A stablecoin card can be used as a corporate card for modern expense management, particularly for global businesses. Companies can issue virtual cards for vendor payments, employee travel, SaaS subscriptions, and other operational spending. Stablecoin-based spending can also support programmable payments and faster settlement for international teams and suppliers. This makes stablecoin-backed cards especially useful for organizations managing distributed teams, cross-border operations, and digital-first finance workflows.

Yes. Stablecoin-linked cards and stablecoin-backed cards refer to the same product — a payment card that lets users spend from a stablecoin balance at merchants worldwide. "Stablecoin-backed" is the term most commonly used by card issuance infrastructure providers, while "stablecoin-linked" is often used by card networks like Visa in press communications. Nium supports both Visa and Mastercard stablecoin card programs through a single API integration.
