Meijer is the latest supermarket chain to jump on the shop-and-scan bandwagon and will roll out the technology to all its stores by the end of the summer, according to a press release.

Meijer's program, called Shop & Scan, enables users to scan bar codes on items as they shop and bag their groceries while they move through the store. 

"Shop & Scan will make the Meijer experience dramatically faster and more convenient for our customers," Terry Ledbetter, CIO for Meijer, said in the release. "This technology joins our curbside pickup and home delivery programs to provide yet another option for Meijer customers to personalize their shopping experience."

The Shop & Scan technology works with Meijer's mPerks program via a free app that customers can download through the Apple App Store or Google Play. Once a customer has completed their shopping, they simply scan their phone at a self-checkout lane and pay.

Meijer launched the initial pilot of the Shop & Scan service in November at Grand Rapids, Mich.-area stores in Standale, Rockford, Walker, Grandville, and Jenison, and two stores in Holland, Mich. Since then, more than 12,000 Meijer customers have downloaded the app.

The Shop & Scan program will begin rolling out in other Meijer stores in the coming weeks and will be available at all 235 Meijer stores by the end of the summer.
