Paul G. Blazer Library’s new Web site, currently awaiting approval, incorporates QR codes into its directory; in it, a QR code has been added next to each faculty and staff member’s name. Serving as green alternatives to the business card, they allow patrons to scan the QR code of the person of their choice and either initiate a call, e-mail immediately, or save that information to their contacts to access at a later time. Therein lies the true beauty of the QR code—it allows a patron to opt-in to a resource at the exact moment the information is needed (Fernando, 2010). This differs greatly from other means of permission marketing, such as subscription-based services like e-newsletters or RSS feeds, where once patrons opt-in, information never ceases being pushed at them. The lack of long-term commitment required by QR codes is a benefit to already information-overloaded patrons.
