The card "allows cardholders to spend USDC directly from their crypto wallets," transferring the USDC balance to Baanx in real-time via smart contracts upon authorization, which is then converted into fiat currency for payment. Baanx is also working with Mastercard to develop a wallet card linked to MetaMask. Baanx stated: "We are empowering people to hold and spend dollar stablecoins in a self-custodial, real-time manner – this is the future of finance."
