Description

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 favorite wallet app, and give it to the lucky recipient. We order in ‘blanks’ – cards with everything but the keypair printed – and print the keypairs ourselves in small batches. The generation process is done entirely in memory and streamed to the printer on a secure computer. You can examine the code for generating cards here. The keypairs are printed, and then the scratch panel applied in a single operation using an IDP Smart 70 card printer. The black ribbon – which contains a negative image of everything it prints – is locked securely in the printer, which is chained to an immovable object. When the ribbon is used up, it’s securely destroyed. While we’re confident in the security and integrity of the keypairs on Ether Cards, we do not recommend storing large amounts of cryptocurrency on them. Ether Cards are intended to be used for low value gifts and payments, and as an easy way to introduce people to the power of the Ethereum blockchain. 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.
