TREZOR - a physical hardware Wallet, independent of the Internet. It contains your secret keys, and the device "knows how" to sign transactions without connecting to the Internet. Even being an autonomous "cold" storage, the hardware Wallet is flexible when performing tasks - both offline and online. With it you can already spend bitcoins at any time. It can be attached to a key chain or worn in a pocket. As you can see, TREZOR allows you to store bitcoins off the network, and when you connect it to the computer, you send the necessary transaction.
This week, the Czech company Satoshi Labs released a preliminary batch of Trezor 2 hardware purse called Model T. Although the Model T is a completely new device, it guarantees the same secure storage of electronic access keys as in the previous version. Satoshi Labs has opened pre-order for the first batch of hardware wallets Trezor Model T with updated functionality. One of the most noteworthy updates is the large RGB touchscreen display that uses the ARM Cortex-M4 processor. Like the first Trezor model, to perform actions related to confidential information, a new device requires the use of commands from the display.
