Questions, answered
How does a WhatsApp QR code work?
The code opens a wa.me link with your number and message, which starts a WhatsApp chat on the scanner’s phone.
Can I change the number later?
Yes. Because it’s a dynamic code, you can change the number or message after printing.
Is it free?
Yes. Every MisterQR feature is free right now, with no credit card and no trial.
