AT&T is helping retailers shorten their checkout lines with its newest product, VeriFone GlobalBay Solutions, that allows associates armed with mobile devices to scan items, apply coupons and discounts, and complete credit card transactions from any location in the store.

The tablet-based solutions also provide the ability to sell items from inventory not available in the store — helping to prevent lost sales — according to a company press release.

Businesses can easily configure this mobile point-of-sale application to meet their specific needs. For example, an electronics retailer may want to load product images and information about extended warranties onto its employees' smartphones or tablets. When a salesperson scans the barcode on an MP3 player, he or she can then make focused recommendations for protection plans and accessories like headphones, cases and car chargers, Chris Hill, VP, advanced mobility solutions, AT&T Business and Home Solutions, said in the release.

"Customers don't want to wait in line or stand around as a sales person runs off to find information on a product — they want great service in a timely manner," he said. "(This) helps businesses complete transactions efficiently and attentively, ultimately helping to drive new revenue generation and increase competitive advantage."

The solution can also change the game in service industries, offering restaurants tableside ordering and payment capabilities, and for hotels, allowing hospitality staff to add purchases to guest room bills, Hill said. By increasing customer engagement and payment convenience, businesses can have a direct — and positive — impact on revenue.
