when we add the amount in sale app and if the user selects to pay it through card then I need to increase the price with 4% and should be printed in receipt.
Do we have any broadcast intents when we enter the amount in sales app or do we have any other method to increase the amount if paid through cards.
As shown in the image when user enters $10.00 and If clicked on charge the amount must be updated to $10.40
