# Free WhatsApp QR Code Generator — Direct Chat & Pre-filled Messages

> Connect with customers on WhatsApp instantly. When scanned, the QR code opens a direct chat window with your business number and an optional pre-filled inquiry text.

## Key Benefits
### No Number Saving Required
Customers don't need to add your phone number to their contacts before sending a message.

### Pre-filled Message Templates
Set default text like 'Hi, I would like to book an appointment' to boost conversion rates.

### Global Country Code Support
Works seamlessly across all international dialing codes with standard wa.me protocol.

## Deep Link Protocol Format
Uses official WhatsApp universal link architecture:
```
https://wa.me/<country_code><phone_number>?text=<encoded_prefilled_message>
```
Scanners are redirected to the native WhatsApp app on iOS and Android or WhatsApp Web on desktop browsers without saving the number to phone contacts first.
