Bitcoin has been getting a lot of coverage in the media lately. Many folks have already used digital Bitcoin wallets in the past. The CoolWallet happens to be a card-like device that lets you store and send bitcoins more conveniently. It features an e-ink display and a flexible, waterproof design. It does not store your private keys in the cloud, so only you will have access.
The CoolWallet relies on NFC for wireless charging. You can send an OTP by tapping the card twice. Users have the ability to check their balance on the display. You also get the WatchDog function to get notified when your phone and card are a certain distance apart. The product will be compatible with iOS, Android, and PC machines.
