Frequently Asked Questions

Will my QR code work on all devices?

Yes, as long as the device has a QR code scanner app or camera with QR reading capability.

Can I track scans of my QR code?

This tool generates static QR codes without tracking. Use a dynamic QR service for analytics.

What’s the best size for printing?

For print, ensure the QR code is at least 0.8 inches (2 cm) square for reliable scanning.

Why does my QR code fail to scan?

Check for typos in the input, low contrast, or damage if printed. Test with multiple scanners.

What types of content can I encode in a QR code?

Our QR code generator supports various types of content:

  • Website URLs (https://example.com)
  • Plain text messages (up to 2,000 characters)
  • Contact information (vCard format)
  • Phone numbers (tel:+1-555-555-5555)
  • Email addresses (mailto:[email protected])
  • Wi-Fi credentials (WIFI:T:WPA;S:Network;P:Password;)
How long does a QR code last?

QR codes don't expire unless the linked content is removed. Static QR codes work indefinitely, while dynamic QR codes depend on the service maintaining them.

Is there a data limit for QR codes?

QR codes can store up to:

  • 7,089 numeric characters
  • 4,296 alphanumeric characters
  • 2,953 binary bytes

More About QR Codes

QR (Quick Response) codes are two-dimensional barcodes that can store a variety of information and are rapidly scannable by smartphones or dedicated QR readers. They were invented in 1994 by Masahiro Hara for Denso Wave, a Japanese automotive company, to track vehicles during manufacturing.

Today, QR codes are ubiquitous and serve many purposes, including:

  • Marketing and Advertising: Linking to websites, product information, or promotional offers.
  • Payments: Facilitating secure and fast mobile payments.
  • Information Sharing: Providing contact details (vCards), Wi-Fi access, or event schedules.
  • Ticketing and Boarding Passes: Used for seamless entry into events or transportation.
  • Inventory Management: Streamlining tracking and logistics in various industries.

Unlike traditional barcodes, QR codes can hold significantly more data, can be read from any direction, and offer robust error correction, meaning they can still be scanned even if partially damaged. Their versatility and ease of use make them an indispensable tool in the digital age.
