Jamaica,

This is not a satisfactory answer.   The question is about the sudden disappearance of the "Swipe Card" button in the "Enter Card Details" screen in QB Online on a computer with a wired card reader.  Not on a mobile device with a Bluetooth card reader. 

That button disappeared after QBO had another update this week.

Please respond.  The question is quite valid and no OS update will correct it.

Thank you.
