Most of your customers already have WhatsApp. Over two billion people use it. The problem is not the app. The problem is getting someone to actually open it and message you.
Think about the current process. Someone sees your business card or flyer. They want to reach out. So they have to save your number, open WhatsApp, find your contact, and then type a message. That is four steps too many. Most people will just not bother.
A WhatsApp QR code removes all of that. One scan and WhatsApp opens with your number already loaded. They tap send. Done.
What a WhatsApp QR code actually does
When someone scans a WhatsApp QR code, their phone opens WhatsApp and starts a new chat with your phone number. They do not need to save your contact first. They do not need to type your number. The conversation is just ready to go.
You can also set a pre-filled message. So instead of the customer staring at a blank text field wondering what to say, they see something like "Hi, I found you on your storefront poster" already typed out. They just hit send.
That little detail changes everything. More on that in a minute.
Who should use this
Honestly, any business that gets customer inquiries over messaging. But here are some that get the most value out of it.
Restaurants and cafes. Put a QR code on your table tent or counter display. Customers scan it to place a takeout order, ask about catering, or make a reservation. No phone tag, no waiting on hold.
Salons and barbershops. Stick the QR code on your mirror, your business card, or your front door. New clients scan it to book an appointment or ask about availability. Way faster than email.
Freelancers and consultants. Put it on your business card, your portfolio, or your email signature. Potential clients can reach you in two seconds without searching for your contact info.
Real estate agents. Add the QR code to your yard signs or listing flyers. Interested buyers scan it and message you directly about the property. You know exactly which listing they are asking about if you use a pre-filled message.
Event vendors. Print the code on your booth signage, your brochure, or your packaging. People who want a quote or want to follow up after the event can reach you instantly.
Where to put your WhatsApp QR code
Anywhere your customers already look. The whole point is to meet them where they are.
Business cards. This is probably the highest-impact placement. Instead of hoping someone types your number into their phone, they just scan the back of the card.
Flyers and posters. Add a small "Message us on WhatsApp" label next to the QR code. People walking by your storefront or reading your flyer can reach you without writing anything down.
Menus and table tents. Great for restaurants that take orders or reservations via WhatsApp.
Product packaging. Let customers ask questions, request support, or reorder directly from the package.
Email signatures. Add the QR code image to the bottom of your emails. Especially useful if you are sending proposals or quotes and want the recipient to reach you on WhatsApp instead of email.
The pre-filled message trick
This is the part most people overlook and it is honestly a game changer for conversion.
When you create a WhatsApp QR code on AQRHub, you can set an optional pre-filled message. That message shows up in the text field when someone scans the code. They do not have to type anything. They just tap send.
Why does this matter? Two reasons.
It removes friction. A blank text field is surprisingly intimidating. People do not know what to say. "Hi"? "I have a question"? A pre-filled message takes that decision away. They scan, they see the message, they send. Zero thinking required.
It tells you where they came from. If you use different pre-filled messages for different placements, you can track your marketing. The QR code on your business card might say "Hi, I got your business card." The one on your storefront poster might say "Hi, I saw your poster." Now you know which channel is driving the most conversations.
This is free attribution tracking. No UTM parameters, no analytics tools, no complicated setup. Just different messages for different placements.

It takes about 30 seconds.
Log in, click create a new QR code, and select WhatsApp as the type. Enter the phone number you want people to message (with country code). Add a pre-filled message if you want one. Customize the colors and pattern if you feel like it. Hit generate.
You get a QR code you can download as PNG or SVG. Print it, share it, put it anywhere.
The QR code is dynamic, which means you can change the phone number or the pre-filled message later without reprinting anything. Got a new business number? Just update it in your dashboard. Every printed QR code will point to the new number automatically.
A note about security
