What's that bar code?

This unique bar code on the lower right of the sticker (known as a QR code) lets customers - and potential customers - instantly learn more about a business, by visiting a mobile version of the business' Place Page on any supported phone. Here's more on how it works and what you can do with it:

  1. Make sure your phone can scan a QR code with its camera, either with an application that you download or via software that's already installed on your phone. To find out what application to use for your phone, we recommend doing a Google search for the model of your phone along with "QR reader".
  2. When you see a QR code, use your phone's application to scan it. If you're scanning a QR code on one of the window decals that we've sent to thousands of U.S. businesses, you'll quickly be taken to that business' mobile Place Page on Google, where you can:
    • Read reviews to see what other users think about the business
    • Find a coupon that the business has posted to their Place Page
    • Star the business to remember to check it out later, or to remember to visit again
    • Leave a review right after you leave the business. What's a better time to write what you think, than when you've just visited?

QR Codes and Books

Books Come Alive with QR Codes & Data in the Cloud


Paper books are a joy to hold and read, but in a hyperlinked world they can feel a little limited. Dr. Sorin A. Matei of Purdue University is making paper books writable and multi-layered with 2D barcodes (QR codes) through a system he's built called Ubimark.

Imagine having a cloud of user-contributed commentary, maps, photos, audio and video annotating the paper books you hold in your hand.

The Great QR Code Scavenger Hunt!

  1. As the teens gather at the library, groups are formed, making sure each group has one or more smart phones with a barcode reader app installed.
    After a brief tutorial on QR Codes and how to use them, the teams are told to search the library for a QR Code hidden on a shelf.

  5. Calendar event.  After adding the Event to their phone's calendar, they see that they need to check in with the Circulation desk.  At the desk, a library staff member hands them a Friends of the Library bookmark with a QR Code attached.  A quick scan takes them to...
  6. A Deep link into the library online catalog.  Quickly, the team runs to the appropriate shelf, grabs the book (which, naturally, has a QR Code on the back dustcover) and scans the code.  One last scan sends a...
  7. SMS Text Message to another smart phone. Right away, they receive a text back, telling the group to head downstairs to the Community room where glory, prizes and refreshments await!
