Creating Barcode Scanner App with URL Launch

Posted on by Egemeny

Hi Community,

I'm seeking your assistance in creating a simple Power Apps mobile app for sales associates. The app should allow them to:

Scan a product Data Matrix barcode using the device's camera.
The app extracts the first 10 digits from the scanned data matrix barcode.
Integrate those 10 digits into a specific URL (e.g. www.google.com/ABCDEFGHI )
Launch the constructed URL automatically in a web browser.

I've already explored the forums and tried using generative AI to create the app, but I'm encountering formula-related errors that I can't resolve.

Here's a breakdown of the desired functionality:

Scanned Barcode Example: ABCDEFG HIJKLMNOPQ (data matrix format)
Extracted Digits: ABCDEFGHIJ (first 10 digits)
Constructed URL: www.google.com/ABCDEFGHIJ (using extracted digits)

I'd greatly appreciate any guidance or suggestions for overcoming the formula errors and successfully building this app.

Thank you in advance for your support!

You just need to add a Scan control to the app. When you scan a code the control holds the data in the Value of the control (Scanner.Value) you can use that data by putting comands in the OnScan property of the control. You could make it as simple as Launch( "https://bing.com Self.Value" ). You may need to be more specific in your search.

Here is info on the Scanner

Here is more info on the Launch command

Hello @Egemeny,

First step.

Click on Settings --> Upcoming features--> Retired --> and turn on Legacy Barcode Scanner.

Use Insert and add Barcode scanner

OnScan property

Set(varScan,BarcodeScanner1.Value)

I have added a text input to store the scanned value

Textinput Default property

varScan

I have added a button to perform the extraction of 10 digits:

OnSelect property of button

Set( ExtractedCode, Mid( TextInput1.Text, 1, 10 ) ); Launch("https://www.google.com/" & ExtractedCode)

When you open the app on mobile and click on scan button it should launch the inbuilt camera app and on sucessfull scan you should be able to see the scanne value in textinput 1.

Please let me know if this works for you.
