Frequently asked questions
How does a WhatsApp QR code work?
The QR code contains your wa.me click-to-chat link. When a customer scans it with their phone camera, WhatsApp opens a chat with your number — with your pre-filled message ready to send. No number saving, no typing.
Where should I put my WhatsApp QR code?
Anywhere customers see you: shop counters and windows, product packaging, menus, flyers, business cards, vehicle branding, exhibition stands, receipts, and posters. Use 512px for flyers and 1024px for large prints.
Can I add a pre-filled message to the QR code?
Yes — type the message in the tool and it's encoded into the QR. Customers who scan it start the chat with that message, so you instantly know which poster or product they came from.
Will the QR code expire?
No. The QR code encodes a permanent wa.me link to your number. It keeps working as long as your WhatsApp number stays active — print it as many times as you like.
Is this free and private?
Completely free, no signup, no watermark. The QR code is generated inside your browser — your number is never uploaded or stored.
What happens after they scan?
ChatMunshi answers every scan automatically — 24/7, in the customer's own language — and books appointments while you work. From $19/month.
