Ledger S Nano Hardware Wallet
At first you’ll think it’s an ordinary USB thumb drive. However, closer inspection reveals that it doesn’t actually have the ubiquitous USB port. That’s because the Ledger Nano S is not a USB drive. Instead, it’s a sophisticated, highly secure cryptocurrency hardware wallet that you can use to keep all of your personal and financial information safe and secure.
Transactions can be checked and confirmed on the Nano S’ display, typically requiring confirmation using the device’s physical buttons. Data is kept secure with a variety of secure technologies while the availability of companion apps makes it a lot easier to manage.
