Standalone hardware bitcoin client: even more anonymity and reliability for bitcoin Radio enabled smartcards as a self-sustainable wireless media: no recharge and no immediate internet connection needed.


The reliability of the Bitcoin system is assured primarily by encryption. The system's main vulnerability is the Bitcoin wallet, created as a file on the computer. If a hacker (or a computer virus) gains access to the computer and can read this file, he (it) will be able to transfer all the money to his (its) anonymous account where it will be nearly impossible to find. It will also be impossible to prove to anyone that you did not voluntarily transfer the money to your own anonymous account.

Our Bitcoincard, a stand-alone device that in effect acts as an electronic wallet, can be used to hide the wallet in a safe place (outside the computer, making it inaccessible to hackers).

    The functions of the Bitcoin smartcard are brilliantly designed. With the ability to self sustain without any recharges. All the digital signature keys are created within the card and remains secure.

    Impressed. Delivery within a week to Singapore. Pheew! I have 24 bitcoins on one card and that's sitting in my drawer, safe and sound.

    Fantastic! I actually want a bitcoin card right now! Fantastic for users who hold large amounts of bitcoins.

    A card where you can keep all of your bitcoins, it's physical and therefore safer than an online wallet, You only have to keep it close to you.

    Nice idea , but there are already many options for securing your btc's and this one does not bring anything new at all.
