Tap, Tap shopping. The fantastic way to shop

Business Insider: From Target to Kroger, grocery stores want to figure out what makes customers tick — and they're using methods that seem straight out of a James Bond movie to find out.

In November, Target expanded its test of beacons installed in LED light bulbs that track and guide customers to relevant products via their cellphones in 100 stores.

With the system, wireless signals travel between customers’ Android devices and the stores’ LED lights, pinging them with promotions, as well as guiding them to relevant and discounted products.

No, got it wrong.  Us, the shopper, will have smart card that track pricing, we gonna have banker bot in our pockets, and the bot loves to price things. So we go tap shopping, and our cards match our personal inventory distribution to the store price distribution. Both sides win, inventory flow becomes accurate yielding greater surplus.
