![]() They can generate and print their own QR codes for others to scan and use by visiting one of several pay or free QR code-generating sites or apps. ![]() Users may receive text, add a vCard contact to their device, open a URI, or compose an e-mail or text message after scanning QR codes. Many of these applications target mobile-phone users (via mobile tagging). An example of this is Philippines National Bureau of Investigation (NBI) where NBI clearances now come with a QR code. They can also be used in storing personal information for use by organizations. Examples of marketing include where a company's discounted and percent discount can be captured using a QR code decoder which is a mobile app, or storing a company's information such as address and related information alongside its alpha-numeric text data as can be seen in Yellow Pages directory.

QR code has become a focus of advertising strategy, since it provides a way to access a brand's website more quickly than by manually entering a URL.

The Quick Response system became popular outside the automotive industry due to its fast readability and greater storage capacity compared to standard UPC barcodes. A QR code uses four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to store data efficiently extensions may also be used. In practice, QR codes often contain data for a locator, identifier, or tracker that points to a website or application.
