A QR code is a square black and white image that is used to contain image. In the case of this particular QR code, you would get all of my basic contact information which would contain my name, mailing address, telephone number, email, and web site. Considering that a QR code is typically used with smart phones, the QR code would be focused on using my .TEL addresses as they are easier to input into the device.
Most QR code readers will have a means of adding the content of the contact details into the phone. You may not find a reader on basic phones, but you should find a QR reader on just about any smart phone OS such as Android, iOS, RIM, Symbian, and Windows Phone. You would need a QR code reader to properly use the image.
