Quick Response (QR) Code: In Simple Terms

In today's fast-paced digital world, you might have seen small black-and-white square boxes on menus, tickets, posters, and product packages. QR codes, or quick response codes, are what people call these. They may seem hard to use at first, but they are very simple and helpful tools that make life easier.

What is a code that starts with QR?

A QR code is a two-dimensional barcode that stores information. It can keep links to websites, phone numbers, product information, payment instructions, and a lot more. QR codes are short for "quick response," which means that a smartphone or QR scanner can quickly scan them.

You can read QR codes from the top to the bottom and the left to the right. This means that they can hold a lot more information than regular barcodes, which can only be read from side to side.

A Brief History

Denso Wave, a Japanese company that is part of Toyota, made the QR code in 1994. The car industry was the first to use it to keep track of parts. QR codes became popular in many other fields over time because they are easy to read and can hold a lot of information.

What does a QR code do?

A QR code is a white background with black squares on it. You can scan the code with your phone's camera or a special QR code scanner. This breaks down the pattern and shows or does what the code says.

• If the code has a link to that page, your phone will open it.
• If it saves your payment information, your payment app will open with the name of the person who will get it and the amount.
• If it saves text, it will only show the message.

How to Use QR Codes

People use QR codes in many different ways. Some of the most common ways to use them are:

• Payments: You can send or get money by scanning a QR code with apps like Paytm, Google Pay, or PhonePe.
