What is hardware wallet?

Guys, who know about different wallets? I have read about trezor a lot https://cryptototem.com/trezor-wallet/ and it seems to be the best option for bitcoin?
Maybe someone knows more :slight_smile:

Another one to consider is the Cool Wallet S.

It uses an innovative way to enter your seed phrase and is useless ( or useful) without a smart phone.
It is a credit card sized device and slightly flexible. It must be charged by the provided USB charging stand and cable.

I thought, only software can be added here. Really? Even hard?

There are a number of hardware wallets that support ZEN.

Horizen launched its own version of CoolWallet S. I think you should take a look!! And yeah you can purchase and pay for it with ZEN :blush:
