We prefer you don't, simply for security purposes. We understand that some folks prefer to give card information over the phone -- however, to preserve the highest level of security for you and your payment information, we ask that you enter this directly within your account. You can do so by logging in, then heading to your Account tab at the top right, and clicking 'view/edit billing information'. This way, you and only you are seeing your credit card number. When you enter it in our system, it gets transferred into a secure and encrypted system that processes your payments. This way, the rezora support staff never even sees your credit card number.
