Security Code

A security code refers to specific data elements on a payment card designed to enhance the security and integrity of transactions. There are two main types of security codes: magnetic-stripe data and printed security features. These codes use secure cryptographic processes to protect the data and reveal any attempts at alteration or counterfeiting.
