You (or anyone else) can scan or read a QR Code with a scanner app that uses the camera in your smartphone. Just download one of the many free QR Code scanning apps to your smartphone -- in fact, you may already have one! 

Here are some free QR Code scanning apps that we recommend, although if you have one you already use that is not listed here it will work just fine. (Also, if you have a suggestion for a better scanning app we'd love to hear from you!) 

• For Android we recommend QR Droid or QR Barcode Scanner. 
• For iPhone we recommend QR Reader (from TapMedia) or Scan. 
  
• For Windows Phone we recommend Microsoft Tag or Scan.
• For BlackBerry we recommend Smart Tags or QR Scanner Pro.
