4.1.4.3 System and Device Data
The system and device data related messages are not addressed by this standard.
However, the MTI 300 series File Action message class (including 362/340), as
explained in the previous section, provides some flexibility to achieve the functionality
similar to what is proposed by the Interface Specification Functional Description. The
File Action messages
are used to:
• Add, change,
delete or replace a file or record
• Inquire into a file
• Perform card administration (such as reporting lost or stolen cards)
Therefore
this message class can be utilized for Negative List, Hotlist, CID Parameter
update
and Application Update messages proposed by the WG4.
4.1.4.4 Event Data
Similar
to the schema in the System and Device Data section, there is no specific
coverage for this message type in this standard. The MTI 300 series File Action Message
class (including 362/340)
can also be utilized to carry event data in the Data Record
data element of the message.
Further definition of the structure, format and content of
this
data element would be required for the event data transmission.

exchange of data between
two institutions to reach agreement on financial totals. The
calculation of the Amount Net Reconciliation data element is achieved by netting
the
debit and credit amounts in the reconciliation message. The standard
defines two types
of reconciliation:
• Checkpoint reconciliation
• Final reconciliation
Checkpoint reconciliation period is defined by the Reconciliation Indicator field in the
message. A final reconciliation period is ident ified with the Date Reconciliation field
and contains any number of checkpoint reconciliation periods. The Reconciliation
Data
Primary
of 12 parts contains all the individual values needed to calculate the net
reconciliation in the Amount Net Reconciliation data element.
