A QR code, or Quick Response code, is a two-dimensional barcode that can be read by smartphones and other devices. QR codes are often used to share links to websites, video, or audio files. While QR codes have been around since 1994, they have only gained popularity in recent years. Thanks to their ability to encode so much information in a small space, QR codes are now used in a variety of industries including retail, healthcare, and manufacturing. 

How Do QR Codes Work?

QR codes are similar to traditional barcodes in that they store information in a machine-readable format. However, unlike traditional barcodes, which can only store up to 20 digits of information, QR codes can store up to 7,089 characters. This increase in capacity is due to the fact that QR codes use a grid-like pattern of squares and rectangles instead of the traditional linear barcode format.

QR codes can be read by devices with cameras and the appropriate software. When a QR code is scanned, the device decodes the information stored in the code and displays it on the screen. For example, if a QR code contains a URL, scanning the code will cause the device to open the website in its web browser. 

QR codes can also be used to store other types of data such as contact information, calendar events, Wi-Fi credentials, and geolocation data. 

Where Are QR Codes Used? 

QR codes are used in a variety of settings including retail stores, museums, workplaces, and public transportation systems. Retailers use QR codes to offer customers coupon codes and product information. Museumgoers can use QR codes to access exhibit audio guides. And some workplaces use QR codes to allow employees to clock in and out of work or track inventory levels. 

Public transportation systems also make use of QR code technology. For example, passengers on Hong Kong’s Mass Transit Railway can use their smartphones to scan QR codes on platform signage in order to view real-time arrival information for their train. Similarly, Beijing’s subway system uses QR codes on tickets so that riders can see how much time they have left before their ticket expires.
