Android Fastest way to do UPI payments with fewest taps?

[Ssreek]

No need to crop but you have to press and hold your finger right on top of the qr code

Ya I'm getting that option now...once I save the photo and go to photos app, it is showing there.
Without saving, only way seems registering for whastapp upi.

i used to use Samsung Pay with a shortcut to be on double tap volume up twice when screen locked and it used to pull up the direct scanner, i used to enter the amount and upi pin that's it. TBH it's the fastest and most reliable upi i used till this date.

I now use BHIM upi since am on ios now and it also has a direct scan option on the launch of app. rest stays the same
