Square just added a very important functionality to their iOS app, the app just added support for Apple watch.
The goal is to let user send money easily with their Apple watch via the Square Cash. Users can send $1, $2, $5, $10, $20, and $100 to their family, friends, co workers or just anyone whom you own money, just select the denomination on the screen and send. The app makes it safer for users to send cash without the need of divulging any personal information, just your username is just enough.
The app already received several positive reviews from its users, the P2P payment system is booming and SQUARE is planning to allow contractors and service professionals to accept money through a new product it calls $Cashtag.
