About QR Codes
QR (Quick Response) codes are two-dimensional barcodes that can store text, URLs, contact info, Wi-Fi credentials, and more. They were invented in 1994 by Denso Wave for tracking automotive parts and are now used everywhere from restaurant menus to payment systems.
Error correction allows QR codes to be read even when partially damaged or obscured. Level L recovers ~7% of data, M ~15%, Q ~25%, and H ~30%. Higher levels make the code larger but more resilient — use H if you plan to overlay a logo.
Capacity depends on the data type and error correction level. A Version 40 QR code (the largest) can hold up to 4,296 alphanumeric characters or 2,953 bytes of binary data at the lowest error correction level.
Common uses: URLs (https://...), plain text, email addresses (mailto:...), phone numbers (tel:...), SMS (smsto:...), Wi-Fi credentials (WIFI:T:WPA;S:network;P:password;;), and vCards for contact sharing.
What is a WiFi QR code?
A WiFi QR code uses the WIFI: protocol format to encode a network name (SSID), password, and encryption type into a scannable barcode. When a smartphone camera reads it, the device automatically prompts the user to connect — no manual typing required. Both iOS (11+) and Android natively support WiFi QR codes.
Common use cases
WiFi QR codes are popular in hospitality settings like hotels, cafes, and co-working spaces where guests need quick network access. They are also used at home to share credentials with visitors without dictating complex passwords, and at events to connect attendees without printing passwords on signage.
// WiFi QR code uses the WIFI: URI scheme
// Format: WIFI:T:<auth>;S:<ssid>;P:<password>;;
// JavaScript — generate WiFi QR code
import QRCode from 'qrcode';
const ssid = 'MyNetwork';
const pass = 'secret123';
const wifi = `WIFI:T:WPA;S:${ssid};P:${pass};;`;
const dataUrl = await QRCode.toDataURL(wifi);
# Python — generate WiFi QR code
import qrcode
wifi = 'WIFI:T:WPA;S:MyNetwork;P:secret123;;'
qrcode.make(wifi).save('wifi-qr.png')Frequently Asked Questions
Is it safe to share my WiFi password via QR code?
Yes, as long as you control who can scan it. The QR code contains the same credentials you would share verbally. This tool generates the code entirely in your browser so your password is never sent to any server.
Do WiFi QR codes work on both iPhone and Android?
Yes. iPhones running iOS 11 or later and all modern Android devices can scan WiFi QR codes natively through the camera app and connect automatically.
