The Scallop card's main advantage is its capacity to conduct secure transaction thus providing a reliable framework. This will enable users and merchants to overcome the challenges involved with accepting cryptocurrency payments in mainstream transactions. 

The Scallop Card, in partnership with Visa, allows you to spend your staked DeFi tokens directly to make payments without liquidating them. Essentially, you can continue to earn yields on your staked tokens and immediately use them in real-world transactions as and when the need arises. It's a win-win!
