What is a QR Code?

A QR code, short for Quick Response code, is a type of two-dimensional (2D) barcode that can store various types of data such as text, URLs, email addresses, phone numbers, and even videos. Developed in 1994 by Masahiro Hara of Denso Wave, Inc., QR codes were initially designed to track parts during manufacturing processes.

A QR code consists of several components:

• Finder patterns: Three square boxes that help the camera find and align with the QR code.
• Alignment patterns: A series of small squares used for fine-tuning the camera’s focus.
• Version number: Indicates the size of the QR code, ranging from 1x1 to 40x40 modules (small units).
• Error correction codes: Ensure that the data stored in the QR code can be retrieved accurately even if it gets damaged or distorted.

Step-by-Step Explanation: Creating a QR Code

To create a QR code, follow these simple steps:

1. Choose an online QR code generator tool (e.g., QRCode Monkey, GoQR.me) or use a dedicated QR code software.
2. Select the type of data you want to store in your QR code (text, URL, email address, etc.).
3. Enter the desired information and configure any additional settings like error correction levels and color schemes.
4. Preview and edit your QR code design if needed.
