QR Code JS

• Generate a QR Code for any input.
• Data stays only in your browser and is not sent anywhere else.
• Open source repository: github.com/danielgjackson/qrcodejs

• Simpler codes are easier to scan:
  • Keep the input as short as possible.
  • If using a URL with a common top-level-domain (such as .com), some readers work without an initial http:// or https://, but it's probably best not to rely on this.
  • All upper-case alphanumeric (with some, e.g. URL, symbols allowed) is more compact than mixed-case, but be careful that any path part may be case sensitive, and some readers may not like the protocol in capital letters.
  • Lower error correction levels can decrease complexity, but may be more susceptible to damage or occlusion.
• Always include a written alternative for the URL.
• Always place the QR code on a 'quiet' area: light on a standard code (if the code is inverted, it should be placed on a dark background).
• For WiFi QR codes, use the format: WIFI:S:my_ssid;T:WPA;P:my_passphrase;;
