The following table lists the parameter ID numbers, descriptions, and values. This table is from
the internal document, NAR SSA Library: Security Part, version 1.23.
The system parameter file is a public file that resides at the root directory of the terminal’s
System & Security Application. This file records the system parameter settings made through
the supervisor menu. The financial application is allowed to read from this file.
Each parameter occupies 16 bytes in the parameter file. A null terminator is required and
saved for character strings, except when the string length is 16. In such case, only 16 bytes of
data are saved.
