The Binance Card is a debit card linked to your Binance exchange balance. You can spend crypto and stablecoins when paying in stores and online; conversion to fiat uses the exchange rate at the time of the transaction.
Application is available in many countries via the Binance app: Card section, application and delivery of a physical or virtual card. Funding is from your main or funding account; you can choose which asset to deduct when paying.
The card is convenient for everyday spending without having to withdraw crypto to a bank account each time. Terms (limits, cashback, fees) depend on region and verification level - check the official Binance site.
