What is QR Code?
A QR code (Quick Response code) is a type of two-dimensional barcode that stores information in the form of black and white squares. It was invented in 1994 by Masahiro Hara, an engineer at Toyota Motor Corporation.
What are QR Codes used for?
QR codes have gained popularity due to their ability to store vast amounts of data such as URLs, text, contact details, and even videos. They are commonly used:
- In marketing campaigns to direct customers to websites or landing pages
- In retail stores to provide information about products
- In event ticketing to display tickets or event details
- In education to create interactive learning materials
- In real estate to share property listings and property videos
How to Scan QR Code
Scanning a QR code is a simple process that can be done using a smartphone or tablet with a camera. Here’s a step-by-step guide:
Step 1: Open the Camera App
Open the camera app on your device, either from the home screen or by searching for it in the app drawer.
Step 2: Point the Camera at the QR Code
Place the device over the QR code, making sure that the entire code is within the frame. You can zoom in and out to adjust the focus as needed.
Step 3: Wait for the App to Detect the QR Code
The camera app will automatically detect the QR code and attempt to read it. Depending on the app you’re using, this may take a few seconds.
Step 4: Tap “Scan” or Select the Corrected Information
If the app successfully reads the QR code, you’ll be taken to the linked website, shown the text, or provided with other relevant information. If the app can’t read the code, try adjusting your camera position and scanning again.
Example Use Cases
Here are some practical examples of how QR codes can be used in real-world scenarios:
Example 1: Restaurant Menus
A restaurant owner can use QR codes on menus to link customers to a website with additional menu information, nutrition details, or even ordering capabilities.
Example 2: Event Promotion
Organizers of music festivals, concerts, or conferences can display QR codes at the event entrance that provide attendees with access to their personalized schedules, performer info, and important venue instructions.
Example 3: Retail Sales Promotions
Retailers use QR codes in product packaging or advertising materials to direct customers to sales offers, discounts, or specific product information.

- Google Lens (Android and iOS)

These apps often come with additional features such as barcode scanning capabilities and the ability to save scanned data.
