Square could get rid of the Dongle, but America is an leveraged nation and we need to pay for most of our expenses using credit cards. Dwolla, Paypal, Serve and others are circumventing credit card companies, but in total I have not seen them have much impact on credit companies and their business model. The only way credit card companies will change their model is for a new, competing card to lower fees for vendors and provide equal service to credit card holders.
