Have you ever gone shopping and get in line to check out—only to find a machine instead of a human being?

When you’re the one responsible for scanning all your items and swiping your credit card, things go a bit faster and makes life a little bit easier,

especially when you’re just picking up a few items.

However, not everyone likes the responsibility of scanning all their items and checking themselves out.

Plus, lines can still build up with these self checkout lanes.

Walmart had a solution for a way to still make customers able to check themselves out, but eliminate lines altogether.

Not too long ago, several stores began to implement their

Scan and Go” technology in which customers are able to scan items as they walk through the store and then pay on their phones when they’re finished.

Then they walk through a Mobile Express lane will at the front of Walmart’s stores for security purposes.

The idea behind using this type of technology was noble—that consumers today want a speedy,

easy shopping experience, and an easy way to get in and get out of the store without any fuss or muss.

Sounds like a win-win for all—Walmart cuts costs, we slash all the long lines, and everyone gets to have a seamless shopping experience, right?

“We’re always looking for new ways to help our customers save time, and these innovations are

just the latest examples of how we continue to invest in our stores and bring greater convenience to customers,” said Ray Korsch, a Walmart market manager, in a statement.
