QR Codes have forever changed the way we make payments. Just scan the code, enter your pin and the payment is done! Most UPI apps also have the option to make payments to a phone number, but payments via QR Codes far outnumber payments made to phone numbers. Not just big and small business, but private individuals can also share their QR Code from their UPI app to receive money.

A QR code can be effortlessly scanned with a smartphone camera or QR code scanner. The ability to store data both horizontally and vertically enhances the usefulness and speed of QR codes.

QR Code Full Form

The full form of ‘QR code’ is ‘Quick Response Code’. It is a two-dimensional code that holds data such as text or website links in a grid format of black squares on a white backdrop. The concept of QR codes was created by Denso Wave Company in Japan in 1994. These codes are designed to swiftly encode and decode information, allowing for rapid data exchange.

How Does A QR Code Work?

Once a QR code is positioned in front of a camera, the scanner begins to interpret the pattern of the QR code. This pattern consists of black squares and dots against a white background. The scanner decodes the information contained within the QR code and then takes action accordingly.

Types Of QR Code

There are various types of QR codes, each distinctly different. Every code features a unique design and serves a different purpose. The first type is the numeric QR code, which encodes numbers to aid in inventory management and tracking serial numbers.

The second type is the alphanumeric QR code, which incorporates both letters and numbers. It is useful for data such as website links, phone numbers, and text messages.

QR codes play a significant role in promoting applications. Each app possesses a unique QR code that users can scan to download the app. This feature also encourages user engagement.

In addition to financial transactions, QR codes assist in accessing websites, videos, and other promotional content. Whether ordering a product or booking tickets, QR codes simplify the process and help minimize unnecessary congestion.
