QR Codes

Explains what QR codes are and how to get started scanning and using them.

What are QR codes?

QR codes, also known as 2-D codes or matrix barcodes, are codes that you can scan with a decoding app that uses your mobile device's camera. QR is short for quick response. Because they are more complex than line-based UPC barcodes, QR codes can accomplish many tasks, for example:

  • directing your mobile browser to a website so you don't have to type the URL
  • displaying text up to thousands of characters long
  • initiating a text message, email, or phone call
  • downloading contact information
  • adding an event to your calendar
  • mapping an address

QR codes were invented in Japan in 1994, and are slowly increasing in popularity in the U.S. To read more about them, visit Wikipedia.
