Resource Guide On QR Codes
Today QR codes have become popular in marketing, advertising and social media industries.
QR stands for Quick Response code. It is a 2D barcode consisting of black modules in a square pattern on a white background found on products, in magazines and a multitude of other places. When scanned with a QR code reader, a user can be taken to a website where more information on the product is available. The barcode consisting of just horizontal lines is a pre-cursor to the QR codes that are so popular today. Unlike barcodes, QR codes encode data both horizontally and vertically, which allows more data to be encoded in a smaller amount of space.
Toyota subsidiary, Denso Wave, originally created the QR code in 1994 to track automobiles during the manufacturing process. Because of their universal readability and large storage capacity, Denso Wave and other companies began to make improvements to the QR code to be used outside the automobile industry. At first, QR codes were frequently used in Japan and the United Kingdom but have become very popular in the US in recent times.

There are security risks when scanning QR codes with a cell phone device. Malicious QR codes can invade privacy rights, link users to dangerous websites and enable applications on your phone such as the GPS feature, camera, or microphone to stream data to a remote site. These actions may happen unknowingly as the browser will pull up a blank page. Cell phone hackers are also creating mobile viruses through QR coding. The hacker can infect the phone with a virus and enable it to automatically send texts to a premium-rate SMS service. Users are charged for unauthorized outgoing text messages. Since the code is not immediately decipherable, you don’t know you’ve been infected until after you have scanned the code. Be cautious of the source you obtain your QR code from to prevent unauthorized use of your phone. Only scan credible sources to ensure you are not infecting your phone with malware or a virus.
