business news in context, analysis with attitude

Tech Times reports that Walmart "is making a move to make grocery shopping more efficient" by "relaunching a mobile app through another test run this year, which aims to help you avoid long lines during your grocery run. Called 'Scan and Go,' the mobile app was released on Google's Play Store on Jan. 9."

According to the story, " The app works as a self-scanning system where all you have to do is to open the app from your phone or tablet, scan the barcode of your items in an in-app shopping cart using your mobile device's camera before dropping them in your trolley. You can also opt to add the grocery item manually if the barcode is not functioning or if you can't find the barcode.
Once you have all of your grocery items scanned, check out your online shopping cart, and pay for your purchases. Simply show the receipt from your phone on your way out.

"What makes the app even more convenient is that you will be able to see the running total of the items in your cart, so you will know if you are overspending or staying within the limits of your budget."
