I have been employed by Fujitsu Services, working on the Post Office Account, formally ICL
Pathway Ltd., since 1996 as a Customer Solutions Architect, involved in many aspects of design
and implementation of the computer system known as Horizon, which is a computerised
accounting system used by Post Office Ltd.
There are three main reasons why a zero value transaction may be generated as part of the
banking system:
1. The transaction has no financial effect (ie a Balance Enquiry or a PIN Change)
2. The transaction has been declined by the Bank
3. There has been some sort of System Failure. Such failures are normal
occurrences.
Each transaction has associated with it a Response Code field which identifies what has
happened. These values are included (together with their descriptions) in the ARQs. In
summary:
RespCd = 1, means that the transaction was Authorised by the Bank. If it is for
zero value, then this means it had no Financial effect. In all the example, such
transactions were PIN Changes or Balance Enquiries where this is indeed the case.
RespCd has a value between 2 and 10 means that the transaction was Declined
by the Bank. The actual value indicates why (eg 3 means that the PIN was invalid
and 4 means Insufficient funds)
RespCd with a value greater than 10 implies some sort of system failure_The_
actual value provides further information as to the nature of the failure within the
overall system
