Unlike most hardware bitcoin wallets, this one is a very tiny computer instead of being a smartcard, but it still offer the feature where private keys are generated offline. This bitcoin wallet also generates a 24-word seed upon set up, and the seed is a very important element because it allows you to recover your wallet in case of theft or loss. The Trezor has its own built in screen where the seed is displayed and copied don during the backup process. Since this is an offline device that can be used in Canada, it can offer you extra security since the seed isn’t displayed on any online computer. If you want extra security, an additional passphrase can be added to this 24-word seed and this is definitely an extra layer of protection because, technically, if anyone finds your seed word they could easily access your funds. It you decide to go for this extra layer of protection, then an attacker would have to have both the 24-word seed and the passphrase in order to access your funds. However, something you need to be wary off is the fact that is the passphrase is forgotten, it cannot be recovered, so you need to make sure you have remember it or have it written down somewhere safe.
