What is a QR Code?

A QR code stands for Quick Response code, a type of two-dimensional barcode that was first introduced in Japan in 1994 by Masahiro Hara, an engineer at Toyota. The primary purpose of QR codes was to track parts during the manufacturing process, but they have since evolved into a versatile tool with numerous applications.

What does “QR” stand for?

In this context, “QR” stands for Quick Response. However, some people mistakenly believe it stands for “Quick Read.” While both acronyms are relevant, the actual meaning is indeed Quick Response.

How Does a QR Code Work?

A QR code consists of a square grid of black and white modules (squares) arranged in a specific pattern. This pattern contains information such as text, URLs, email addresses, phone numbers, and more.

Here’s a step-by-step explanation of how a QR code works:

Step 1: Creating a QR Code

To create a QR code, you’ll need to provide the desired information (text, URL, etc.) and choose the type of QR code you want to generate (static or dynamic). This is typically done using a QR code generator tool.

Step 2: Scanning a QR Code

When someone scans your QR code with their smartphone’s camera app, the device uses a QR code reader app to decode the information contained within. The decoded data can then be accessed directly on the phone or opened in an associated app (e.g., Safari for URLs).

Step 3: QR Code Reading Process

The QR code reading process involves:

• Capturing an image of the QR code using a camera
• Processing the image to identify the QR code pattern
• Decoding the information within the QR code
