File contents

QR Factory

Generate QR codes for various data types with customizable appearance.

Requirements

Python 3.8+
pip install qrcode[pil] (qrcode + Pillow)

Instructions

Determine QR type and build payload:
- URL: Raw URL string (e.g., https://example.com)
- WiFi: WIFI:T:<WPA|WEP|nopass>;S:<SSID>;P:<password>;;
- vCard: BEGIN:VCARD\nVERSION:3.0\nN:<last>;<first>\nTEL:<phone>\nEMAIL:<email>\nEND:VCARD
- Email: mailto:user@example.com?subject=Hello&body=Hi
- SMS: smsto:<number>:<message>
- Text: Raw text string

Generate QR code:

import qrcode
qr = qrcode.QRCode(version=None, error_correction=qrcode.constants.ERROR_CORRECT_M, box_size=10, border=4)
qr.add_data(payload)
qr.make(fit=True)
img = qr.make_image(fill_color="black", back_color="white")
img.save(output_path)

Output: Save as PNG to /tmp/qr_<type>_<timestamp>.png or user-specified path. Return the file path.

Customization Options

Size: Adjust box_size (default 10, range 5-20)
Border: Adjust border (default 4, minimum 4 per spec)
Colors: fill_color and back_color accept color names or hex codes
Error correction: L (7%), M (15%), Q (25%), H (30%) — higher = more resilient but larger

Edge Cases

Large data: QR version auto-scales (fit=True), but warn if data > 2KB (may not scan well).
Special characters in WiFi: Escape ;, :, \, and , in SSID/password with backslash.
Missing Pillow: If PIL import fails, run pip install Pillow and retry.
Binary data: Not recommended for QR — suggest a URL link instead.

Security

WiFi passwords: Warn user that QR codes containing passwords are readable by anyone who scans them.
Sensitive data: Never generate QR codes containing API keys, tokens, or secrets unless explicitly requested.
Sanitize file paths to prevent directory traversal.
