Why can’t I enter in a Card Verification Value (CVV) in the iOS app?

A CVV is not required for a successful transaction. However, it may be required by your payment gateway. For our iOS app, in a swiped transaction, the CVV will not be taken. If you are encountering an error with transactions while swiping a card, trying manually keying in the card information to confirm that the CVV is the problem. If it is, you may want to contact your payment gateway.
