WhatsApp QR code generator for flyers, counters and events

The QR code is a picture of a wa.me click-to-chat link: your number in international form and, if you write one, the opening message. When a phone scans it, the camera reads that link and opens WhatsApp with a chat to your number. Nothing sits in between, so there is no short-link or tracking service that could go down, ask for a subscription or be switched off.

The flip side is that a printed code cannot be edited. If you change your WhatsApp number or want a different message, you make a new code and replace the old prints, so put a number on it that your team will still be answering months from now.

A QR code belongs where people cannot click: a billing counter, a standee at the shop entrance, a delivery box, a product label, a table tent in a café, a trade fair stall, a property site board, or a hoarding at a bus stop or metro station. The customer already has a phone in hand, and the code saves them reading out ten digits and typing them correctly.

Example: a Jaipur sweet shop printing Diwali gift-box flyers might make one code with the message "Hi, I'd like to order Diwali gift boxes" for the flyer, and another with "Hi, I'm at your Malviya Nagar counter" for the stand beside the till. Each scan arrives as a chat that already says what the customer wants.

Contrast and space matter more than decoration. Keep the code dark on a plain, light background, leave a clear white margin on all four sides, and don't stretch it, crop it or print text over it. Curved bottles and shiny laminates can make a code harder to read, so test those surfaces in particular.

The right size depends on distance. A code on a counter stand, scanned from arm's length, can be small; one on a poster across a room or a hoarding across a platform needs to be far larger. Rather than trust a rule of thumb, print a proof at the real size and scan it from where your customers will stand.

Put a short line beside the code that says what happens, such as "Scan to chat with us on WhatsApp", and print the number underneath for anyone whose phone won't scan.

Because every code can carry its own opening message, you can tell placements apart without any tracking. Chats that begin "Hi, I saw your stall at the expo" came from the expo; chats that begin "Hi, I got your flyer with my order" came from the delivery box. Customers can edit the message before they send it, so treat it as a strong pointer rather than an exact count.

Rename each PNG after its placement as soon as you download it, such as whatsapp-qr-expo-stall.png or whatsapp-qr-gift-box.png, so the right code reaches the right printer.
