The upcoming issue of Engagement 101 Magazine includes an ad by Ze Jewelry that uses QR technology. QR codes are little bar codes that appear in advertisements. The code, when snapped using a mobile device, displays more information about the ad.

This one for Ze Jewelry takes you to a page full of product shots. Once you click on the product, it takes you to an enlarged shot where you can choose to share, tweet or email the product. Pretty cool, huh?
