The latter is engineered to enable merchants to secure payment card data and remove it from their environment while allowing access when needed. The new First Data Secure Transaction Management service is powered by the RSA SafeProxy architecture and aims to cut back on the cost and complexity of complying with the Payment Card Industry Data Security Standard (PCI DSS).
By using the First Data Secure Transaction Management service, payment card data is encrypted at the time it is captured by the merchants existing point-of-sale application and remains encrypted until it is delivered to the First Data authorization switch where decryption occurs. Once authorized through the switch, the card number is replaced by a token value that cannot be linked back to the original card data, but otherwise behaves like a card number. When needed, merchants can access the original card number through a secure vault that First Data maintains for controlled authorized look-ups.
