You know those QR codes that Ralph Lauren Rugby is using so you can use your phone to buy clothes instantly? Well, a couple designers have a new idea about how to use them. Marguerite Charmante and Wolfgeng Peter Schmiller put QR codes on a dress, and, hypothetically, a guy could see a girl waiting for a drink at the bar and scan the code on her dress using his phone. Instantly, he could be directed to her Facebook page (or blog, or whatever website she wanted), and he could assess whether or not he wanted to go after her. Just another way technology could help us become creepy stalkers! [Make]
