Most people know QR (quick response) codes – the small, square patterns showing up mostly in print ads. Load a QR reader app onto your smartphone, take a picture of a QR code, and the app takes you to a webpage designated by the advertiser. But they can do lots more, too. A QR code on the back of a business card can bring your phone number or e-mail address up on the viewer’s smartphone. Or send a text message. Or display a password to enter a drawing. And they’re not just for ads – they can be employed on everything from direct mail to billboards – even apparel. So if you decide to use QR codes, it’s worth a brainstorming session to consider all the ways they can help prospects connect with you.
