grocery shopping until the weekend, curse your way through the irate Sunday morning hordes, and then schlep your food all the way home only to realize you forgot to buy dish soap and use those coupons. Good thing, then, that SK Telecom is trialing a new service that syncs items from a smartphone app -- like a shopping list -- to its tablet PC-equipped Smart Cart. Hailed by the company as the first of its kind, this real-time aide uses indoor positioning to provide product info, tips and discounts while you peruse those crowded aisles. The WiFi-connected in-cart display also makes use of augmented reality, offering coupon clippers a high-tech solution for their cost-cutting predilections. If the current pilot test in China's Shanghai Lotus Supermarkets proves a success, expect to see this "personalized smart shopping service" doling out recommendations based on purchase history and location. Hear that? That's the sound of marketers licking their hyper targeting chops. Full PR is after break.
