Ether cards are ‘physical ether’. They’re a quick and convenient way to give ether, tokens, or other blockchain assets to friends and family, and a great way to introduce people to the power of the Ethereum blockchain. Each card has its own unique Ethereum address, printed on the back in QR code and text form, and a private key, hidden under a scratch-off panel. To use one, simply scan the code, deposit some Ether or tokens using your favourite wallet app, and give it to the lucky recipient. When they want to redeem it, they can scratch off the panel, and use their own wallet app to ‘sweep’ the funds into their newly created account. Each unscratched card’s security is guaranteed by a smart contract.
