The Square card reader is a very innovative piece of technology that has helped to change the usage of credit/debit cards. It allows you to plug right into your phone and use these cards simply by swiping which helps to avoid the hassle of constantly having to input the information. The origins of this device have been under dispute for quite sometime now and it has gotten even more contentious with the chairman James McKelvey not on the list of inventors on the patent. There will be a court order which will try to add his name onto the list of inventors so we will have to wait and see what happens to the Square Company.
