How QR Codes Work
A QR (Quick Response) code is a 2D matrix barcode that stores up to ~4,000 characters — far more than a traditional 1D barcode. Any modern smartphone camera reads it instantly, with no app required. Built-in error correction means a QR code still scans even if part of it is dirty, creased, or covered by a logo. That reliability is why QR codes now power menus, tickets, and payments worldwide.
QR Code for WiFi
Share your WiFi without reading out a long password. A WiFi QR code encodes the network name, password, and security type, so guests point their camera and connect in one tap. Perfect for cafés, offices, Airbnbs, and home guests — print it and stick it on the wall.
QR Code for a Restaurant Menu
Replace printed menus with a QR code that opens your menu page or PDF. Diners scan the code on the table and browse on their phone — cheaper than reprinting, and instantly updatable when prices change. Link it to a hosted menu or a PDF you build with our images-to-PDF tool.
QR Code for Business Cards & Instagram
Add a QR code to a business card, flyer, or storefront that opens your website, LinkedIn, Instagram, or a saved contact (vCard). One scan and the person has your details or follows you — no typing a handle. Ideal for networking events, packaging, and shop windows.
QR Codes for Payments & Inventory
QR codes drive mobile payments (UPI, PayPal, and wallet links) across much of the world — generate one that opens your payment link so customers pay by scanning. For inventory and retail checkout, a traditional 1D barcode is often the better fit; create those with our Barcode Generator.
