After the invention of barcodes in the late 1940s, they rapidly developed to become sophisticated tools for reading data quickly. However, the market still called for a more complex system of decoding information. This is when "Quick Response" code or QR-Code was invented. Standard barcodes are unable to provide information such as links to websites or contact details. Unlike barcodes, QR-Codes are two dimensional, that is, they can store information in both the vertical and horizontal directions. Therefore, a QR-Code can hold considerably greater volumes of data than a standard barcode. Accordingly, you can use QR-Codes to store a variety of data including your contact information.
