Tony Fadell is renowned for designing Apple's original iPod music player and for being co-creator of the first iPhones, before going on to develop smart thermostats at Nest. On Tuesday, the famous engineer revealed his latest product: a hardware wallet he built for the crypto firm Ledger.
The new wallet, called Ledger Stax, comes with an E-Ink display that covers the front and curves around the spine of the card-like device, letting users easily view transactions as well as their favorite art.
