guys, unlike simple products, their smart counterparts are endowed with various electronic sensors, a capacitive battery, speakers, and in some models even a screen. All these functions help to find a wallet when lost, charge your mobile device, instantly pay in contactless terminals, monitor your spending, protect Bank cards from remote reading and much more. So I think it is good device.
I find in New York famous brand of smart wallet - Wallor wallet. I want to buy it because this tool like powerful and has interesting modern design. Smart wallet has gps tracker, Wireless Phone Charging,Rechargeable battery and other useful options.
