This wallet is distinguished by a reduced form factor. Indeed, thin like a credit card, it can find its place in your wallet and does not require a USB connection to operate. These exclusive characteristics make it a product that deserves special attention. Ah and this is my favorite wallet.
This wallet card does not need to be physically connected to a computer. Everything is done by Bluetooth, you will only need to be equipped with an iOS or Android smartphone to use the necessary software interface in order to interact with the physical medium. The use of CoolWalletS is based on a mobile application available on most modern smartphones (Android 5.0+ / iOS 9.1). This application acts as an interface between the physical medium, the user and his resources.
