    Note that the cards are not pre-loaded with Ethereum. You will need to buy a card, and add value to it yourself.

    Give the gift of Ether

    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 and are made with utmost security. 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.

    My Ether Wallet is a popular browser-based Ether wallet that doesn't require installation to use.

    Creating a Wallet
    Go to https://www.myetherwallet.com/, and choose "Generate Wallet". Enter a secure password, and click the "Generate Wallet" button. You'll be provided with your new wallet address, and the opportunity to download the "Keystore/JSON file". Save this somewhere safe, and be sure to back it up. Make a note of your address.

    Importing your Ether Card
    First, use a mobile phone barcode scanner to scan and copy the QR code for your Ether Card's private key.

    At the MyEtherWallet site, click on "Send Ether". Under "Select the format of your private key", choose "Private Key", and paste the private key you copied earlier, then click "Unlock". MyEtherWallet shows you a screen with your address and account balance.

    Copy the address of the new wallet you created at the beginning, and paste it in the box titled "To Address". You should always copy and paste - never type the address, as it's easy to make a typo!

    Next to "Amount to Send", click "Send Entire Balance", then click "Generate Transaction" and "Send Transaction", and you're done!


    How secure are Ether Cards?

    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.

    For additional assurance, we provide a guarantee: Some ether from the sale of each card is set aside in a contract account for a year from the date of production. You can verify that a deposit on your card has been paid using this tool. If presented with an Ether Card whose private key panel is undamaged, but whose account has outgoing transactions, or a card whose private key is illegible, we will refund to you from the guarantee account the balance stored on the card before the first outgoing transaction, up to a maximum of 50 times the amount of the deposit. We reserve the right to adjust the maximum amount of this guarantee as the price of Ether fluctuates over time.
