How to Generate QR Code?

QR codes or Quick Response codes are matrix barcodes which can be interpreted by certain camera phones and QR barcode readers. The messages can be generated by a QR code generator in the form of text, URLs or graphics which can be used in a number of ways by different types of business organizations for sending and receiving information. QR code generators can be used to print advertisements and information such as product details, contact information, competition details, event details, offers, Twitter/Facebook or MySpace IDs, and links to a particular YouTube channel. A mobile device can be used to generate a QR Code too.

Since the information in QR code is easy to interpret, the user no longer need to type lengthy information, which reduces the risks of errors. Primarily, there are three variables in QR code which include the display size, code density, and scanning distance. Collectively, they help to form optimized QR codes. The scanning distance is dependent on the density and display size. In case the code density increases, the functional distance reduces and the display size remains the same. Inversely, if the code density reduces, the display size remains the same but the functional distance increases.
