Walmart is trying to ease the minds of people who are already stressing about holiday shopping.
It's giving its employees in the busiest sections of its stores with mobile scanners to check customers out quicker.
The scanners will eliminate the need for customers to wait in ridiculously long holiday lines.
Walmart also hopes to help customers find items in its stores more easily.
The company is populating its mobile app with detailed store maps that will lead shoppers directly to products.
