What Is a QR Code and How to Make One for Free

QR codes are those square, pixelated barcodes you scan with your phone camera. They can store links, text, Wi-Fi details and more.

How QR codes work

A QR (Quick Response) code encodes data as a pattern of black and white squares. Your phone's camera reads the pattern and instantly opens the link or shows the text — no app needed on most phones.

What can you put in a QR code?

• A website or product link
• Your contact details or business card
• Wi-Fi login for guests
• A UPI/payment link
