have you at least used the search engine on this forum and searched for it? There are plenty of examples in here!

EDIT: Less than a minute, from posting the above, making a quick search using the word "barcode" and getting countless examples.
here's one: https://www.b4x.com/android/forum/threads/b4x-b4xpages-barcode-reader.120417/

Try to download the project in this post:

i search more result show,but some is by 2015,and more can't run in new android system like 34 VERSION

Does the B4A library have a package manager tool?

If the B4A library can be searched directly in the IDE, but it is not installed on the computer, click to find the online library, list 5, double-click to automatically install to the default library list, custom library directory, or temporary directory (for testing only)
Each library has a testing project. The information in the library includes: suitable Android version range (such as 10-30), and the last update time.

This is like the Nuget package manager developed by VS2022.net.

Many source code examples cannot run on new phones.

have you try my project ??

Are you testing it on a real device? With Google Play Services?

Also check this very simple library: [class] Google Code Scanner - no permission, very simple to use, barcode scanning
It will not work if Google Play Services is missing.

您是在真实设备上测试它吗？使用Google Play服务？

还要检查这个非常简单的库：[类] Google代码扫描仪 - 无许可，非常易于使用，条形码扫描
如果缺少Google Play服务，它将无效。

That info is crucial and should have been explicit from post #1.
Whe went from "how to read qrcodes" to "how to read qrcodes WITHOUT google services"
Its a completely different question and so are the answers!
I say it again... use the search function, browse through the results, and you WILL find what you are looking for!
