There were whispers on Saturday that the glitch was a result of cyberterrorism or hackers, but Target tweeted a statement saying that was not the case.
"The temporary outage today was the result of our internal technology issue that lasted for approximately two hours."
Target also said that no guest information was breached at any time.
In their initial tweet, Target said that it's "aware of a systems issue in store and are working as quickly as possible to get this fixed."
Social media users reported cash registers were not functioning properly at dozens of stores across the country and posted images of long lines.
Despite the long lines, customers in Tinley Park stayed light-hearted saying the glitch wasn't a big deal because no one spends less than 45 minutes in a Target. Annette Ponziano, who was shopping at the time out the outage, said the employees were very nice.
"They offered water, they were really nice to everybody waiting in line and when they did come back up, it looked like they checked everybody out quick," Ponziano said.
The same type of glitch happened in 2014, also on June 15, where the cash registers were down.
Target has 1,800 locations in the United States, and a large presence in India.
