QR Codes & Public Pages
Printed QR codes that stay useful after they are printed: change where they lead, see the chats and paid orders each one brought in, and turn every scan into a lead in your WhatsApp CRM.
Printed QR Codes That Stay Useful After They Are Printed
The problem today
A QR code on a flyer, a price tag or a business card is usually a dead end the day it is printed. When the offer, the product or the page changes, every copy already in the world points at the wrong place, nobody can say how often it was scanned, and the person who scanned it never reaches your CRM.
How Klaros solves it
Every Klaros QR code prints a short link on your own self-deployed domain and is looked up each time it is scanned. You can see how often each code is scanned, send it somewhere new, or retire it with a fallback, and the printed code never changes. Card and product codes open a page with a WhatsApp chat button and a contact form, and a lead left there lands in your CRM tagged with the card or product it came from.

Customer Situations
Printed codes go stale the moment the offer or the page changes.
The Problem
A shop prints 5,000 flyers for a festival sale. The sale ends, the landing page changes, and every flyer still in a drawer or on a notice board now sends people to an expired offer. Reprinting is the only fix, and nobody knows which flyers were ever scanned.
The Klaros Way
Each Klaros code resolves when it is scanned, so the owner points it at the next offer in seconds, or retires it and chooses where scanners should land instead. The dashboard lists every code with its scan count and when it was last scanned.
Technical Differentiator: A /q/ indirection on your own domain, with a repoint, retire and fallback lifecycle, a record of every scan, and a short reference that follows the scan into the chat.
Expected Impact: Print once, keep it working, and see which printed piece earns its keep.
Every printed code is listed with the chats and paid orders it brought in and its last 30 days of scans, and can be sent somewhere new or retired without reprinting.
Nobody knows which poster, table or flyer actually brings customers.
The Problem
A restaurant puts a QR code on every table and a poster in the window. Chats arrive all day and orders follow, but at the end of the month nobody can say whether the window poster earns its space or which tables start conversations.
The Klaros Way
Each code, and each table in a set, adds a short reference to the WhatsApp message it opens. Klaros reads it back out of the first message, marks the chat with the code it came from, and credits that person's paid orders to the first code they came through. Every code in the dashboard shows its chats, paid orders and revenue.
Technical Differentiator: Attribution carried in the chat itself, read by the inbound pipeline and joined to orders when the numbers are read, one code per customer, so two posters never claim the same sale.
Expected Impact: Print where it sells, and stop paying for print that does not.
A chat that began at a printed code is marked with that code in the inbox, and the contact shows it as how they found you.
Paper business cards get lost, and the people who kept them never reach the CRM.
The Problem
A sales executive hands out 500 cards at a trade fair. Most are lost in pockets, the numbers are never saved, and the few who do get in touch arrive with no record of where they met.
The Klaros Way
A Klaros digital card opens from its QR code with Save contact, Chat on WhatsApp and a contact form. A person who leaves their number lands in the CRM tagged with that card, and the card shows its scans and leads.
Technical Differentiator: A vCard built on the card page, and lead capture that writes straight into the CRM contact graph with the card as its origin.
Expected Impact: Fewer lost contacts, and every networking lead traceable to the card that produced it.
The card page saves your contact in one tap, and offers WhatsApp and a contact form.
Generic black-and-white codes look like an afterthought on premium print.
The Problem
A jeweller designs a beautiful counter card and then pastes a plain generated QR code on it. A designer adds a logo by hand, the code stops scanning, and the problem is found only after the print run.
The Klaros Way
Klaros draws every code in the brand colour with a centre logo, refuses colours too pale for a phone camera, and builds logo codes with the highest error correction so the logo does not cost a scan. Each code opens as a print-ready poster, a sheet of twelve stickers and a printing guide, or downloads as PNG or SVG.
Technical Differentiator: Error-correction level H whenever a logo is present, a contrast check before saving, and vector output named after your own card or product.
Expected Impact: On-brand print material that scans the first time, without a designer in the loop.
Codes carry your colour and logo and are built to keep scanning with the logo in place; each opens as a print-ready poster, sticker sheet and printing guide.
How it works
- Create: in Pages & QR, choose where the code takes people: a chat with you on WhatsApp (built from your own number, nothing to type), your card, a product or any website. Make one code, or one per table, branch or stall.
- Style and print: every code carries your colour and centre logo. Download a PNG or a vector SVG, or open a print-ready poster, sticker sheet and printing guide to print or save as PDF. A set of codes prints on one sheet, each labelled with its name.
- Scan: the phone camera opens a short /q/ link on your domain, which is looked up at that moment and sent to the current destination. A code that opens an ordinary website tags the visit for your own analytics.
- Capture: card and product pages offer Chat on WhatsApp, Save contact and a contact form. The WhatsApp message carries the code's short reference, so the chat is traced to the code that started it; a lead lands in your CRM tagged with the card or product.
- Manage: see each code's chats, paid orders and revenue, 30 days of scans, and a flag when a working code goes quiet; rename it, change where it leads, or retire it with a fallback, from the dashboard, the API or an AI assistant over MCP.

Frequently Asked Questions
Are the QR codes static or dynamic?
Dynamic. The printed image holds a short link on your own domain that is looked up every time it is scanned, so you can change where it leads, retire it, or set a fallback without reprinting. Every scan is counted.
Can the QR codes carry my brand?
Yes, and it is included with every workspace. Set a colour and a centre logo once and every code you show or download uses them. Colours too pale for a phone camera are refused, and codes with a logo use the highest error correction so they keep scanning.
How do I print them?
Download a print-resolution PNG or a vector SVG for your print shop, or choose Print or PDF for a ready poster, a sheet of twelve stickers with cut guides, and a one-page printing guide with sizes by scanning distance.
What happens to a printed code when its card or product is removed?
It goes wherever you set as its fallback. With no fallback, the person scanning sees a short, neutral page saying the code is no longer active. It never sends your customers to us.
How does attribution work for print materials?
Every scan is recorded. When a card, product or WhatsApp code opens a chat, the pre-filled message carries the code's short reference, for example "#K7Q2XM". Klaros reads it from the first message, marks the chat with that code, and counts that person's paid orders toward the first code they came through, so each code shows its chats, paid orders and revenue. A code that opens an ordinary website tags the visit for your own analytics (utm_source=qr, the code's name as the campaign) instead, and you can switch that off per code.
What if a customer deletes the reference before sending?
Then that one chat is not linked to a code. Nothing else changes: the chat, the customer and any order work as normal, and the scan itself is still counted. Most people send the pre-filled message as it is.
Can an AI assistant or another system manage QR codes?
Yes. /api/v1/qr-codes lists every code with its results and creates, bulk-creates and updates codes, and the Klaros MCP server gives an assistant list_qr_codes, create_qr_code, create_qr_codes and update_qr_code, so it can answer "which poster made money".
Do you take a markup on the WhatsApp infrastructure cost for this extension?
No. Klaros never sits in the payment or messaging path. You connect your own WhatsApp Business Account (WABA) and pay Meta directly. "Zero markup" is a structural guarantee.
Can I trial this extension before committing?
Every workspace starts with a 14-day free trial of the core CRM, and can see every extension and what it does. Switching an extension on is part of a paid plan: message us on WhatsApp and we will turn it on for you.
Where is my conversation data stored?
All data lives in your own isolated Cloudflare D1 database and R2 buckets. Klaros is self-deployed infrastructure, giving you total data sovereignty and zero vendor lock-in.
