New York (CNN Business) Walmart wants customers to find products more easily and check out faster this holiday shopping season.

Starting Thursday, the retailer will station store workers in the busiest sections of its 182,000-square-foot supercenters and smaller stores. The company is outfitting those workers with mobile checkout scanners to ring up customers on the spot.

Walmart ( WMT ) says the mobile scanners will allow shoppers buying big, bulky items such as Christmas trees and flat-screen TVs to bypass registers at the front and head straight to their cars.

"We put a lot of work in our stores on the checkout experience," Steve Bratspies, Walmart's chief merchandising officer said on a call with reporters Monday. "We're always looking for new ways to do it. We think this is one that — particularly at the busy holiday time — customers are going to really appreciate."

Walmart is also adding detailed digital store maps to its mobile app to allow shoppers to quickly find aisles and products.
