Identify UPI Payment QR Code with barcode scanner

How can app identify qr codes of upi payment companies?
Actually I am koding a QR CODE SCANNER App , I want a procedure in the app to identify a UPI QR CODE of any company like PAYTM, GOOGLE PAY , PHONE PE .
This feature is embedded in IPHONES to identify any qr pay directly from the app.
that’s why I am building an app to make it happen for android users also…
IF ANYONE HAS SUGGESTION RELATED TO IT , PLEASE REPLY…

After scanning you got the result text->
check whether text contains upi://pay this type of statement if yes than it’s a upi based qr code

I don’t know all upi based qr codes follow this or not but mostly have the similar pattern like that

Yes you are right but how can I put that procedure in the app.

What do you want exactly ?? Say clear in words

when my qr scanner app scans a upi qr code , it should identify the upi payment company and proceed to pay.
