Developers Pavol Rusnak and Marek Paletinus wanted to help keep your Bitcoins safe, so they decided to bring them into the real world with the TREZOR. TREZOR is a mini handheld computer with a single purpose -- to safely store your Bitcoins.
The device acts as both a storage device and as a guardian. When you want to access your digital currency, TREZOR asks you to physically push a button. Only the required amount is then sent through to your computer. As a result, you can safely use Bitcoins on even a compromised computer.
In addition to virtual security, the TREZOR also offers physical. If you ever lose your Bitcoin wallet, you don't have to worry about losing your coins because of a built-in passphrase. In addition, a security hologram sticker makes sure that no one tampers with the device during transit.
