What is a QR Code?
QR (Quick Response) code is a two-dimensional barcode that smartphones and tablets can scan with their camera. When scanned, it instantly opens a URL, displays text, dials a phone number, connects to WiFi or performs any action you encode into it.
QR codes were invented by Denso Wave in Japan in 1994 for tracking automotive parts. They became mainstream for consumer use around 2010 when smartphones with cameras became widespread. Today they are one of the most used technologies in digital marketing and contactless interactions worldwide.
What Can You Encode in a QR Code?
Website URLs The most common use. Encode any website address and anyone who scans the code goes directly to that page without typing anything.
WhatsApp Links
Encode https://wa.me/923001234567 to let customers message your WhatsApp business directly by scanning a code on your shop counter or business card.
Phone Numbers
Encode tel:+923001234567 and scanning the code automatically prompts the user to call your number.
Email Addresses
Encode mailto:info@yoursite.com and scanning opens the email app with your address pre-filled.
SMS Messages
Encode sms:+923001234567?body=Hello to let customers send a pre-written SMS with one scan.
WiFi Password
Encode your WiFi credentials so guests can connect without typing the password. Format: WIFI:S:NetworkName;T:WPA;P:YourPassword;;
Contact Information (vCard) Encode a full digital business card with name, phone, email, address and website that saves directly to the scanner's contacts.
Plain Text Any text message, address, instructions or information can be encoded and displayed when scanned.
Payment Links Encode JazzCash, EasyPaisa or bank payment links for contactless payments at your shop or restaurant.
Google Maps Location Encode a Google Maps URL to let customers navigate directly to your business location.

How to Create a QR Code — Step by Step
Best Practices for QR Codes
Use High Contrast Colors Black on white is the most reliable combination. Avoid light colors on light backgrounds or dark on dark. Low contrast QR codes fail to scan in different lighting conditions.
Minimum Print Size For printed materials, your QR code should be at least 2cm × 2cm (about 0.8 inches square). For banners and large format printing, make it proportionally larger so people can scan from a distance.
Always Test Before Printing Before printing thousands of business cards or packaging, always test your QR code with multiple devices — different phone models and QR scanner apps. What works on one phone should work on all.
Shorten Long URLs If your URL is very long, use a URL shortener like bit.ly or tinyurl.com first. Shorter URLs create simpler QR codes that scan more reliably and look cleaner.
Add a Call to Action Place text near your QR code telling people what to do and what they will get. "Scan to view menu", "Scan to WhatsApp us" or "Scan for 10% discount" dramatically improves scan rates.
Consider Where It Will Be Scanned QR codes in locations with poor lighting or at distances over 3–4 meters need to be larger and higher contrast. Plan your QR code size based on where it will actually be used.
QR Code vs Barcode — What is the Difference?
How QR Codes Work Technically
A QR code contains data encoded in a pattern of black and white squares. The pattern includes:
- Finder patterns — The three square corners that help scanners locate and orient the code
- Timing patterns — Alternating black and white modules that help identify cell size
- Data modules — The actual encoded information
- Error correction — Redundant data that allows the code to be read even if partially damaged or covered
Frequently Asked Questions
Are QR codes free to use? Yes. QR codes themselves are free to generate and use. Some services charge for advanced features like analytics tracking or dynamic QR codes that can be edited after printing.
Do QR codes expire? Static QR codes — like the ones our tool generates — never expire. The URL or text you encode is permanently stored in the code itself. Dynamic QR codes that use redirect links can expire if the service is discontinued.
Can I put a logo inside a QR code? Yes. QR codes have built-in error correction that allows up to 30% of the code to be obscured while remaining scannable. You can overlay a small logo in the center without affecting functionality.
How many characters can a QR code hold? A QR code can hold up to 4,296 alphanumeric characters. For practical use, keep URLs under 200 characters for the most reliable scanning experience.
What is the difference between static and dynamic QR codes? Static QR codes have the URL or data permanently encoded — they cannot be changed after creation. Dynamic QR codes use a short redirect URL, so you can change the destination without reprinting the code. Our tool generates static QR codes.
Can QR codes be used for payments in Pakistan? Yes. JazzCash and EasyPaisa both support QR code payments. You can generate a QR code containing your payment link and customers scan it to send money directly to your account.
