Appinventor barcode scanner database

hello, I will make an application from appinventor, this application will read the barcode and if it is the same as the barcode in the database, it will send it to a different page, but I cannot register the image in the database beforehand and I do not know how to call the barcode the same, can you help?

Show your relevant blocks and database connection / configuration

how can I do it

Here is a sample using bar codes and Google Sheets ...

You can use Windows logo key + Shift + S to take a screenshot on Windows or use a different screenshot tool.

CloudDB or a different database?

Right click on some white space in your blocks editor, then downlolad blocks as image. Post the image back here.

Then tell us about your proposed "database" and how it is configured to work with AI2
