What is a security code?
About security codes
A security code is a 3 or 4 digit number printed separately from your credit card number, which you must enter as a security measure to prevent unauthorized use during online transactions.
Security Code Authentication
When paying by credit card, authentication using a security code is required. By entering the security code, the security of your credit card payment is improved and fraudulent use is prevented.
