1. Check QR codes
You'll be seeing more of these postage-stamp-shaped "quick response" graphics in and around the grocery store in the coming year as retailers and food manufacturers learn how to put this relatively new technology to work. Using your bar-code-reading smartphone, you take a picture of the QR code to access extra information about the product at hand. Look for food packages to feature QR codes that, when scanned, yield nutrition facts and recipes.
