WhatsApp QR codes for instant customer contact
Where to use WhatsApp QR codes
Print them on business cards, packaging, restaurant tables, or event banners. A scan opens a chat directly — no phone number to type, no contacts to add.
Pre-filled messages improve conversion
Adding a message like "Hi, I'd like to know more about your services" removes friction. The customer just hits Send, making it more likely they follow through.
