A QR Code, or "Quick Response Code", is a smart/mobile phone readable barcode. If you need a QR Code reader, go to the app stor on your smart phone and search for "QR Code Reader." You'll find several FREE apps. Run the app and then hold your phone's camera over a QR code to read it. The information encoded may be a URL, phone number, SMS message, V-Card, Google map directions, plain text, or other data.
