A Quick Response (QR) code is a two-dimensional barcode that can be scanned by smartphones, tablets, and other electronic devices. When scanned, the device's camera captures the two-dimensional proportions of the code which will then interpret the information embedded in it. Most QR codes consist of a plain black square with four smaller squares located in the centre.
qr code scanners, also known as QR code readers, are programs that allow a person to scan and interpret the information found in a QR code. To do this, the person needs to open the app, typically by aiming the device's camera to the QR code. Once the scanner app reads the code, the person can typically view a text message, a website, a coupon, or other types of data.
QR code scanners can be found in many app stores and can be used on both Android and iPhone devices. In addition, there are dedicated QR code scanners that are designed solely for scanning QR codes. Some QR code scanners may even be built into an existing app on the device, such as the camera app.
Using a QR code scanner can be useful for a variety of different tasks. For example, some businesses may use QR codes to quickly send individuals to an online store, or to get customers to review their products or services. Likewise, individuals can use the code to quickly find out more information about something they're interested in, or to join a particular service.
