NFC payment option gives error "please present one card only" when my app reads NFC card
From other questions, I understood that Clover flex now allows app to use NFC reader for reading cards for non payment purposes.
I have written a small app that reads the NFC data from a card when it is tapped when the app is open.
My app works and is able to read NFC data.
However, I notice that once the app is run, the Sale app of Clover flex stops accepting tap payments. It gives an error 3 error messages
CARD READ OK
