Quick Response (QR) code software is typically designed to either create or read certain images. QR codes are two-dimensional (2D) graphics, usually square in shape, that consist of lines and squares that represent information. One of the most common types or QR code software is a program that can be used to create these images, which can be fairly simple or include additional tools to make them more elaborate. There is also QR code software that is designed for a device to read these graphics, allowing the data stored within them to be accessed.
Some of the most common forms of QR code software are programs that can be used to create these images using different types of information. Many of these applications are fairly simple and allow someone to choose the input data that is then embedded into the graphic. This can include many different types of information, such as plain text in the form of a person's name and contact details, or links to websites. Some types of QR code software can be used to make different versions of graphics, which can encode particular types of data, such as interactive contact information.
There are also QR code software programs that allow for more complex or visually dynamic forms of graphics. Many codes generated by basic programs are in black and white and have little visual appeal, which is often efficient for use in a warehouse but may not be effective for marketing. More elaborate programs can be used to create images that include colors to make them stand out and seem more attractive. There are even QR code software programs that can be used to add images to these graphics, though this must be done carefully to ensure that the addition does not impede its usability.
The other common type of QR code software is used to read these images once they are made. Different types of devices allow users to view the data embedded in a graphic, including smart phones and computers. QR code software can be installed onto these devices to allow someone to easily use them to scan a code and to display the information contained within it. Many of these programs are quite simple and are able to read just about any type of graphic and show the data within it. There are other types of software, however, that are more effective and can instantly take a user to a website contained in an image, rather than displaying the link as a prompt.
