A QR code (quick response code) is a type of two dimensional (2D) bar code that is used to provide easy access to online information through the digital camera on a smartphone or tablet.
A QR code works similarly to barcodes at the supermarket. Each QR code consists black squares and dots which represent different pieces of information. When scanned, the unique pattern on the barcode translates into human-readable data. This transaction happens in seconds.
Quick Response code
A QR or Quick Response code is a two-dimensional bar code, which you can scan to access a website, an application, or other media. It's like scanning a bar code in a supermarket, but better
Most Android and iOS mobile devices are equipped with a native QR Code reader in the camera. Give it a try by simply opening the camera app on your phone and point it toward a QR Code. If a notification appeared that prompted you to click on it, then you have a QR Code scanner built-in.
QR Code is capable of handling all types of data, such as numeric and alphabetic characters, Kanji, Kana, Hiragana, symbols, binary, and control codes. Up to 7,089 characters can be encoded in one symbol. A QR Code symbol of this size can encode 300 alphanumeric characters.
QR codes offer multiple benefits to businesses, such as increased exposure, inexpensive advertising, data collection, convenience to customers and enhanced brand recognition. QR codes can also save time and money for consumers by providing quick and easy access to information
Technically, a QR code doesn't “expire.” Like static QR codes, they're just a matrix of squares that contain information. But because dynamic QR codes can be made to redirect to any new information at chosen times, they can effectively expire
The data in a QR code is a series of dots in a square grid. Each dot represents a one and each blank a zero in binary code, and the patterns encode sets of numbers, letters or both, including URLs. At its smallest this grid is 21 rows by 21 columns, and at its largest it is 177 rows by 177 columns
Barcodes and QR codes are two types of systems that can be used to store various types of data. The primary distinction between a barcode and a QR code is that a barcode can only store data in one dimension, whereas a QR code is capable of storing data in two dimensions
QR (short for “quick response”) codes, invented in 1994 by the Japanese manufacturer Denso Wave, are often a 32×32 matrix of squares that are either black or white. As such there are a total of 1024 squares and a total of 21024 variations are possible, which is on a par with 10308.
In 1994, DENSO WAVE (then a division of DENSO CORPORATION) announced the release of its QR Code. The QR in the name stands for quick response, expressing the development concept for the code, whose focus was placed on high-speed reading

QR codes are widely used by several industries for various purposes such as brand monitoring, tracking time, processing record, object recognition and other general communication applications. QR codes can be broadly classified into 2 types – Static and Dynamic QR codes.
There are 7 different elements in a QR Code.
Do QR codes collect my personal information and data? QR code-generating software does not collect personally identifiable information
Requires internet connection. QR codes also require an internet connection in order to function. People with otherwise-compatible smartphones may have low signal or no access to Wi-Fi, preventing them from accessing whatever is behind the QR code. Distrust and unfamiliarity
