WALMART has reportedly faced several tech incidents that have sparked concerns around the safety of data and information.

One of these incidents had temporarily taken out the retailer’s cash registers at thousands of its stores for several hours.

Walmart’s internal tech systems have reportedly faced more than a dozen “major incidents” recently, according to Business Insider.

A “major incident” is supposedly a problem that has affected operations or the company’s revenue collection, according to an employee who spoke to Business Insider.

An internal email had reportedly been sent by the company’s tech leaders to staff which noted the apparent issues.

These systems have supposedly faced sixteen major issues since February 1.

A Walmart staffer also reportedly said another two of these major incidents had occurred this week, according to Business Insider.

The retailer’s tech platform has controlled its e-commerce, in-store payment systems, and distribution centers.

Most of Walmart’s core business operations have been run using this technology.

A Walmart spokesperson confirmed that the phrase “major incident” is used among its team.

“Major incident does not mean something is material to our business,” they said.

“Our business is strong, our infrastructure is industry-leading, and most importantly, millions of people around the world continue to rely on us every day.”

This representative also did not deny the incidents that had reportedly taken place.

Thousands of Walmart stores had been plunged into chaos in February after a temporary software glitch caused cash registers to go down.

Some cash registers were left totally inoperable and that caused some customers to walk out of stores, The U.S. Sun previously reported.

Other locations also reported that they were unable to complete customer’s returns in stores.

While some technical issues were resolved fairly quickly, this problem lasted hours.

A Walmart spokesperson at the time had ruled out any external interference with its tech systems. 

The retailer had confirmed to The Wall Street Journal that the glitch had come from an issue in its internal system.

Some business experts have shared their concerns over the potential security risks with incidents like this.

Daniel McCarthy, a professor at Emory University’s Goizueta Business School, said outages could also be security concerns, according to Business Insider.

“This could expose sensitive consumer information such as usernames, passwords, and credit card numbers,” McCarthy said.

Mark Cohen, a professor at Columbia Business School, blasted the retailer for these issues.

“There is no excuse for shoddy software development, installation, and maintenance,” Cohen said.

“If Walmart’s philosophy was, ‘We have zero tolerance for risk,’ then these problems would likely not occur.”

The U.S. Sun has reached out to Walmart for comment.
