Change Pay I.D.

[DrEdErris]

I switched phones with my wife. She and I have Note 5's. I have my Pay set up with my I.D. on my Note 5. How do I delete and/or change the i.d. on my wife's phone so that she can have her own account? Uninstalling the app does not delete the info in the Pay Framework so reinstalling just restores the wrong info again. I have a Samsung account set up for her with her email and password, but, I cannot get that info into the phone. Thanks.
