Why are the banks and their customers in the United States still using checks? [duplicate]
Because it makes money for all parties, and because the general public is reluctant to any change. Who should have an interest to change that? People. And they have no say in it. You can actually do a lot without paper checks nowadays (I only use one per year for car taxes, as they do not accept anything else), but many people shake their heads about even online banking and would never trust it.
