"Like many other companies, Target is using NCR as a vendor to facilitate the acceptance of payments, and on Sunday, NCR encountered a problem in one of its data centers," said Target.
NCR could not be contacted for comment Sunday night.
Target also recognized the weekend events of its customers in short excuses.
"We know that many customers have had a frustrating shopping experience in our stores this weekend," said Target. "For that, we are really sorry."
The latest failures have not gone unnoticed online.
Target said that Sunday's incident was not related to Saturday's number. The company has 1,800 locations in the United States and a presence in India.
