A Quick Response Code or a QR Code is a is a type of matrix barcode (or two-dimensional barcode) that encodes much more data than a standard 1D barcode. It encodes alphanumeric information. The encoded data can easily be decoded and read by a QR Code Scanner application on a smartphone.
In fact, many smartphones such as iPhone, Xiaomi, Motorola, and Samsung now have in-built QR Code scanning feature in their stock camera application.
QR Codes have also become common in consumer advertising. Typically, a smartphone is used as a QR Code scanner, displaying the code and converting it to some useful form (such as a standard URL for a website, thereby removing the need for a user to type the URL into a web browser).
Today, they are commonly added to:
- Business cards to allow people to save contact details
- Class material to engage and teach children
- Print advertisements to allow readers to visit the website, register for an event, etc.
- Mobile payment applications to make transactions
- Product packaging to allow consumers to get detailed product information
- Event or travel tickets to authorize and log entry
- Wedding invitation to make things easier for the guests
- Invitation cards to help guests get the venue location on their phone’s maps application
