Why Use QR Codes?
Tooly thinks QR codes are super useful! They act like a bridge between the physical world (like posters or packaging) and the digital world (like websites or apps). Here's why they're great:
- Instant Access: Users scan and immediately get info, visit a site, or connect to Wi-Fi. No typing needed!
- Versatile: Link to websites, share contact details, provide event info, show locations, and much more.
- Contactless: Perfect for menus, payments, or information sharing without physical contact.
- Trackable (with services): You can track how many times QR codes linked to specific URLs are scanned.
- Cost-Effective Marketing: Easy and cheap to add to print materials or digital displays.

Tooly's Tips for Effective QR Codes
Creating the code is easy with Tooly! Follow these tips to make sure your QR codes work great:
Size Matters
Ensure the code is large enough to be scanned easily from the intended distance (min 2x2 cm / 0.8x0.8 in often recommended for print).
Keep the Quiet Zone
Always leave a clear border (whitespace) around the code. Tooly adds a basic margin, but ensure it's clear in your final design.
Maintain High Contrast
Dark code on a light background (like black on white) is most reliable. Avoid light-on-light or colors that are too similar.
Test, Test, Test!
Always test your QR code with different devices/apps before distributing it. Make sure it goes where you want!
Provide Context
Briefly explain what scanning the code does (e.g., "Scan for Wi-Fi," "Visit our site"). Don't leave users guessing!
Understanding QR Codes
QR codes (Quick Response codes) are like advanced barcodes. They store information in a grid of black and white squares that smartphones and other devices can scan quickly. Invented in Japan for the automotive industry, they're now used everywhere to bridge the physical and digital worlds.
Their versatility allows them to store various data types, making them incredibly useful for marketing, information sharing, payments, and more. Tooly helps you create standard QR codes easily!
Common QR Code Data Types
Website URL
The most common use. Scans open a webpage directly. Just enter the full URL (e.g., `https://tooly.tools`).
Plain Text
Encode any short message, note, or piece of information. Great for quick notes or instructions.
Wi-Fi Network
Allows users to connect to Wi-Fi easily. Use format: `WIFI:T:<WPA|WEP|>;S:<NetworkName>;P:<Password>;;` (replace T, S, P values).
Contact Info (vCard)
Share contact details that can be saved directly. Requires specific vCard formatting (search online for 'vCard QR code generator format').
Geolocation
Point to a specific location on a map. Use format: `geo:<latitude>,<longitude>`.
Calendar Event
Create an event that can be added to a calendar. Requires specific VEVENT formatting (search online for details).
About Error Correction
QR codes have built-in error correction. This means they can still be scanned even if partially damaged or obscured! There are four levels:
- Low (L): Recovers ~7% damage. Less dense code.
- Medium (M): Recovers ~15%. Good balance (Tooly's default!).
- Quartile (Q): Recovers ~25%. Denser code.
- High (H): Recovers ~30%. Densest, best for harsh environments but harder to scan if small.
Troubleshooting: QR Code Not Scanning?
If your generated QR code isn't scanning correctly, Tooly suggests checking these common issues:
- Low Contrast: Colors too similar? Increase contrast (e.g., black on white).
- Too Small: Printed/displayed too small? Generate a larger size.
- Too Complex/Dense: Lots of data + low error correction? Shorten data (use URL shortener?) or increase EC.
- Insufficient Quiet Zone: Ensure clear space around the code.
- Scanning Angle/Lighting: Scan directly in front, ensure good light without glare.
- Damage (if printed): Scratches/marks interfere, especially with low EC.
