A more featured device compared to Trezor One, containing an SD card reader and a stronger ST STM32F427VIT6, allowing greater support for more demanding cryptocurrencies and FIDO2 Authentication. FIDO2 authentication is theoretically possible to be implemented on lower-tier Trezor One, but the plans are currently on hold (https://www.reddit.com/r/TREZOR/comments/f8uza0/comment/finvd9n/?utm_source=share&utm_medium=web2x&context=3). The device also features a touchscreen which is a departure from the computer-reliant input of Trezor One device, allowing the device to be a bit more airgapped by requiring entry of a PIN code on it’s touch display rather than on the computer, which could be potential points of attack.
