What is a QR code?
A QR code (short for "quick response code") is a type of barcode designed to be scanned by a smart phone's camera that typically links to a website when scanned.

What do I need to scan a QR code?
First, you need a smart phone.

​Second, while some iPhones allow QR code scanning directly from their camera app, a free QR code reader app can be downloaded from either the iPhone App Store or Android Google Play Store app.
This is an example of a QR code! Try scanning this and see if you can successfully link to the Taste of 'Dena online auction landing page.
I downloaded a QR code reader app! How do I scan a QR code?
Once you have a QR Code reader installed on your smartphone, you’re ready to scan your first QR Code. Doing so is very easy. Just follow these simple steps.
  1. Open the QR Code reader app on your phone.
  2. Hold your device over a QR Code so that it’s clearly visible within your smartphone’s screen.
    Two things can happen when you correctly hold your smartphone over a QR Code.
    1. The phone automatically scans the code.
    2. On some readers, you have to press a button to snap a picture, not unlike the button on your smartphone camera.
  3. If necessary, press the button.

Presto! Your smartphone reads the code and navigates to the intended destination, which doesn’t happen instantly. It may take a few seconds on most devices.
