QR (quick read) barcodes are a quick and easy way to share information between mobile devices. “QR business card” allows you to create several different business cards with different information in them. For example you can have a personal and work card as well as one with just your e-mail address. To share a card tap on the card to open it and then go to the page with the QR barcode. Let your friend scan the barcode with his mobile device. To receive a card on a Windows Phone 7 device open Bing and tap on the Visual Search icon. Scan the QR barcode and import it in your contact list. On iPhone, Blackberry or Android use an appropriate QR reader application. Never run out of business cards again!
