Walmart expanding use of the “Scan & Go” for iPhones

Wal-Mart Stores Inc. is expanding use of the “Scan & Go” feature for its iPhone app to 40 stores in the Denver area. It has been testing the technology in stores in Atlanta, San Jose, CA, Northwest Arkansas, and Portland, OR, according to Internet Retailer.

Scan & Go enables shoppers to scan the bar codes on products as they put them into their shopping cart. When the shopper has completed shopping, she presses the Done Shopping button on the iPhone app, which generates a custom QR code. The self-checkout terminal scans the QR code off the phone, tallies the items, and instructs the shopper to select a payment option to complete the transaction at the terminal.

In October 2012, Wal-Mart announced that NCR will install 10,000 self-checkout terminals in more than 1,200 Wal-Mart locations in the U.S. by the end of 2013. Some of the devices being installed are new additions and some will replace current equipment, the spokeswoman says. More:
