During the payment when i insert the credit card in the card reader and it displays "processing..." for some seconds, then it leads me to a signature screen where i need to sign it in order to proceed with the payment. When i sign it and hit the "Authorize" button it displays "processing" and then it returns to the main menu screen without displaying any errors. The transation is not made and doesn't enter to Authorize's panel. What could it possibly be?
