Banking groups are bucking the notion of the U.S. Postal Service getting involved in banking after the USPS rolled out a pilot program in four locations.

Last month, the Postal Service began allowing customers to cash payroll and business checks at its locations (up to $500) in exchange for disposable gift cards. Aaron Stetter, executive vice president for policy and political operations with the Independent Community Bankers of America, said that his group feels as though the rollout is a “foot in the door” for the government to weigh future, expanded proposals.
