Payment method adding problem

New Member

Hello! My name is Jin Seok Lee from Republic of Korea. I am going to book several tickets to visit Swiss. But when I reach to payment section, I try to add my check card to pay, but error has occurred. Even though I type it correctly. The error code is DTR- 1403.
