CoolWallet is a Bluetooth hardware wallet for managing Bitcoin, Bitcoin Cash, Ethereum, Litecoin, Ripple, and ERC20 Tokens. It represents a cold storage wallet that can be used as the Android/Apple mobile app. 

Private keys are encrypted offline by the chip located inside the card. No user data is stored by CoolWallet. It’s possible to add custom tokens to the wallet. Physical and biometric 2FA protection is in place for the wallet users. Changelly and Binance DEX are the integrated exchange options.

As a more secure option, one can use CoolWallet as a wireless device of a credit card size. At the time of writing, the Single wallet’s price is $99 and the Duo’s wallet price is $159 (the latter includes two Coolwallet devices). Upon a purchase a buyer is charged with the New Taiwanese Dollars. The Elliptic Curve Digital Signature Algorithm (ECDSA) is supported here.

It's a cool device. It looks like a credit card, but it keeps money. Total safety. You can be sure that nobody is going to steal something from you.
