16.1 Security Features
16.1.1 Variable Object Security Features
The application uses a module named Transaction Engine Variable Object to recognize if a variable is
keeping any of the following account data:
PAN
Cardholder Data
Full Track Data
Sensitive Authentication Data
Account Data
16.1.2 Transaction Object Security Features
In order to make sure storage of cardholder and full track data is in the database only when it is actually
