The department is looking into whether Visa abuses its position in the debit card market, and limited merchants’ ability to route transactions through less expensive networks.
“The US Department of Justice has informed Visa of its plans to open an investigation into Visa’s US debit practices,” Visa writes in a securities filing.
“We have received a notice to preserve relevant documents related to the investigation. “We believe Visa’s US debit practices are in compliance with applicable laws.”
