By Rahul Kumar · · 9 min read
QR codes (Quick Response codes) are two-dimensional barcodes readable by any smartphone camera. In India, QR codes have become ubiquitous — from restaurant menus to UPI payment collection to government services. Here is everything you need to know to create and use QR codes effectively.
Types of QR Codes
- URL QR: Most common. Scans to any website or landing page.
- UPI QR: Accepted by Google Pay, PhonePe, Paytm, BHIM. The merchant shows a UPI QR; the customer scans and pays.
- WiFi QR: Encode SSID + password. Guests scan to join without typing credentials.
- vCard QR: Share complete contact details in one scan.
- Text QR: Display a short message on scan.
Static vs Dynamic QR Codes
Static QR codes encode the destination directly — you cannot change where they point after creation. They're free forever and ideal for permanent use (business cards, signage). Dynamic QR codes use a redirect URL — you can update the destination anytime. They require a paid service but are essential for print materials you intend to update.
