Caoliao QR Code

Site Introduction

Caoliao QR Code (cli.im) is one of the more widely used QR code generators and dynamic QR code management platforms in China.

Whether individuals doing check-in/sign-up, small teams managing equipment inspections, or enterprises creating one-code-per-item asset tags, it can all be handled here. It works directly via WeChat scanning, with no extra app installation required.

Core Features

1. Multiple Types of QR Code Generation

Supports text, URLs, files, images, audio/video, business cards, WeChat, forms, etc.

Generate codes directly on the homepage, with support for batch generation, QR code beautification, and layout/printing onto A4 paper.

Basic operations for creating static QR codes or dynamic QR codes are all here.

2. Dynamic QR Code Content Can Be Updated Anytime

After the code is posted, changes made in the backend take effect in real time when scanned.

This is especially convenient for scenarios that require frequent updates, such as product introductions, service guides, and electronic manuals.

4. Data Collection and Collaborative Management

Scan-to-fill forms, photo GPS location, watermark trail, with real-time data aggregation and export.

The paid version supports member permissions, multi-level approval, and data API push, suitable for teams implementing workflows such as scan-to-register and inspection closed loops.

Comparison with Similar Platforms

Unique Advantages

1. Very low barrier for the free version: QR code generation, scanning, storage, and form collection are basically unlimited, unlike many tools that cap the free tier or show ads.
2. Dynamic QR + business system in one: Not just a generator, but can also build complete workflows such as equipment inspection and asset management.

Practical Highlights

• 200+ templates ready to use; just tweak and go live, no need to build from scratch.
• Operate directly via WeChat scanning; batch generation + label layout means you can start using codes as soon as they're printed.

Objective Drawbacks

1. Free version images are standard definition with watermark, and the scan page has a Caoliao logo; for formal commercial use, you need at least the Basic version.
2. For complex business logic and deep system integration, it is not as strong as professional low-code platforms.

FAQ

1. What is the difference between Caoliao QR Code and ordinary QR code generators?

Ordinary generators create static codes; the content is fixed and cannot be changed. Caoliao's core is dynamic QR codes — content is stored in the cloud, and changes in the backend take effect in real time when scanned. It also supports business functions such as forms, inspections, and asset management, not just "making a code."

2. Is the free version really enough for long-term use?

The official clearly states that basic functions are free forever — QR code generation, scanning, storage, and form collection are all unlimited. The main limitations are: images are standard definition with watermark, the scan page has the Caoliao logo, and audio/video trial playback is limited to 5 people for 30 days. It is sufficient for daily use by individuals or small teams.

3. When do I need to upgrade to the paid version?

If you need to remove watermarks, display your own brand, play HD images/audio/video in large quantities, multi-user collaboration with permissions, or data API integration — these require starting from the Basic version (¥780/year). For larger teams or deep data export, look at the Advanced or Flagship versions.

4. Will posted QR codes expire?

No. Codes generated by both the free and paid versions are valid long-term. After printing and deployment, you don't need to worry about them becoming invalid. When the paid version expires, you only lose access to paid features (such as branding removal); the codes themselves remain valid.

5. Does scanning with WeChat require installing an app?

No. Scanners just need to use WeChat to scan. Administrators can use the WeChat mini-program or web backend to view data and collaborate across multiple devices.

6. What about data and security?

Caoliao has China's Multi-Level Protection Scheme Level 3 (MLPS 3) certification. The paid version provides capabilities such as operation log auditing, data recovery from accidental deletion, and blockchain evidence storage. For specific security solutions, see the "Data Security" section on the official website; government and enterprise users can request contracts and special VAT invoices (13% tax rate, self-service application in the backend).
