This document provides an overview of ATM reconciliation. It defines ATM reconciliation as monitoring all aspects of an ATM transaction from cash loading to dispensing to identify any failures. Daily reconciliation is needed to balance the ATM "till" like a human teller by comparing the ATM journal, cash levels, and banking application. It outlines the various parties involved in ATM transactions and the accounting entries for different transaction types. Risks associated with ATM operations like cash pilferage or mapping incorrect accounts are also discussed.

3. General Description of ATM
The Automated Teller Machine (ATM) is a machine that enables customers carry out basic financial
and non-financial transactions without necessarily coming into the banking hall. Such transactions
include cash withdrawals, account balance enquiry, mini statements, bill payments e.t.c.
ATM can be installed through the wall or placed in the lobby. Characterized by stout and decent,
safe and reliable, easy to maintain. It is very suitable for banks, postal savings to provide self-
service to the public, and will offer a general solution for your automatization desire.

5. Parties involved in ATM
When a card is used in an ATM, several parties are involved.
1. Cardholder
A cardholder is the person to whom a plastic card has been issued by a card issuer. Typically, the
cardholder is responsible for all charges on and debit transactions against that card.
2. Card issuer
A card issuer is an institution (typically a bank or card scheme) that issues cards to its account
holders. The issuer is ultimately responsible for authorizing transactions against the cardholder’s
account. Once a transaction has been authorized, the issuer deducts the transaction amount from
the cardholder’s account and is then responsible for settlement; that is, insuring that payment is
made to the acquirer either directly or via the card scheme (e.g. MasterCard or Visa).
3. Acquirer
An acquirer is a bank or institution that provide /own the ATM
4. Processor
Processors acquire transactions that originate at ATMs owned by third parties (usually independent
sales organizations - ISOs). They then process these transactions, routing them via regional and
national networks to issuers. They also receive settlement from the issuing banks and distribute this
to the various participants who facilitated the transaction (e.g. ISOs).

6. CLASSIFICATION OF ATM TRANSACTIONS
There are basically three types of transactions, which can exist under the ATM network of any bank.
They are the following
1. On-us transaction:
2. Remote-On-us Transaction:
3. Not-On-us-transactions:
In modern terms this three basic terminology have change to:
1. On-us transaction OCOM (Our Card Our Machine)
2. Remote-On-us Transaction OCTM (Our Card There Machine)
3. Not-On-us-transactions: TCOM (There Card Our Machine)

7. Accounting Entries
ON US (OCOM)
Any time there is OCOM transactions, the Customer’s account is debited for both the actual amount
and charges. While ATM Cash GL account is credited with the actual amount,
The system automatically:
 Debits the customer’s account with the transaction amount
 Credits the ATM CASH GL with the transaction amount

8. Accounting Entries
REMOTE ON US (OCTM):
Any time there is OCTM transactions, the Customer’s account is debited for both the actual amount
and charges where applicable. While payable account is credited with the actual amount, the ATM
fee payable account is credited with the charges.
The system automatically:
 Debits the customer’s account with the transaction amount
 Credits the payable account with the transaction amount
 Debits customer’s account with charges where applicable
 Credits fee payable with the charges.

9. Accounting Entries
NOT-ON US (TCOM)
The system automatically:
• Debits Receivable account
• Credits ATM Cash GL

10. Operation of the ATM
The following are the nuggets concerning the operation of the ATMS
• ATM terminal is installed and attached to a General Ledger on CBA.
• ATM cash is operated like an impress system i.e cash remaining in the ATM is retired into the
branch (cash unload) and fresh amount loaded into it (Cash Load)
The following are the accounting entries passed during the operation of the ATMS
• It is expected that the ATM cash GL reflects the real position of cash available in the ATMs at
any point in time.
• The ATM cash GL is expected to be nilled off at the point of cash unloads.

13. Associated Risks in the Operations of The ATM
Activity Risk Implication Mitigant
1 ATM set up Mapping wrong GL to the ATMs *Distortion banks books i.e GL carrying unusual balances.
*spurious postings into such GLs are not easily detected
*reconciliation of ATM cash with balances on
GLs
2 Cash Load *loading lower amount on ATMs than
amount posted into the ATM GLs.
*Cash pilferage.
*GL carrying unusual debit balances
*
*Daily reconciliation of ATM cash related
transactions
*Periodic ATM cash investigations
*Loading in the presence of control officer
3 Cash Unload *posting lower amount than actual cash
unloaded from ATM into the GL
*Cash Pilferage
*ATM GL carrying unusual balance
*Reconciliation
*unloading in the presence of control officer
4 Unusual activities *Direct pilferage of cash from the ATM i.e
reduction of cash balances from ATM
without the use of customer’s card.

17. ATM RECONCILIATION
The need for the reconciliation of ATM cannot be over-emphasised. Just like human tellers balancing
their Teller tills, ATM tills need to be balanced on a daily basis. If this is done the risks associated
above would be mitigated and deviations from standard easily and quickly identified for necessary
action.
ATM reconciliation involve the monitoring of the total life cycle of an ATM transaction. It start from
the point of cash load into the ATM to the point of cash dispense. It try to provide the answers to
questions such as :
How
Why
When
What
Of a transactions failure.
With reconciliation you can determine at what point a transactions failed. E.g. is it at the point of
request, or at the point of authorization or at the point of dispense.
ATM reconciliation is best done by an automation process. We have a lot of Application that automat
the reconciliation process of ATM

18. ATM RECONCILIATION
ATM Reconciliation Process
ATM Reconciliation should be done daily by designated staff. Just like a human teller balance his till
daily the ATM is expected to do the same. ATM Reconciliation has two aspects. Cash reconciliation
and ATM Transactions Reconciliation.
The following are the Reports need for the Reconciliation
ATM Electronic Journal …………………… ATM Machine
ATM cash GL Transaction…………………. Banking Application

19. ATM RECONCILIATION
ATM Reconciliation Process
RECONCILIATION RESPONSIBILITY FREQ Process
Cash Reconciliation:-
Review of ATM Journal Balances to
physical cash counts in ATM Machine
canisters and Reject Bins
BRANCH Daily or At
each Cash
loading
(The Cash activity is a process to determine the
expected physical cash remaining in the ATM
machine.
Get the cash loaded posted on your CBA and deduct
all cash withdrawals on the ATM from the point of
the cash load using either Postilion or the E-journal).
ATM Transactions Reconciliation :-
ATM CASH GL VS ATM ELECTRONIC
JOURNAL
BRANCH ……. Daily  Spool ATM transactions from your CBA
 Spool ATM cash withdrawal transactions from
Postilion or E-Journal
 Match the two set of data using agreed matching
criteria e.g. RRN or Stan depending on the data
set

20. ATM RECONCILIATION
ATM Reconciliation Process
Cash Reconciliation is done to determine
The expected Physical Cash in the Machine at any point in time.
To compare the cash offloaded in the ATM Machine with the Expected Physical cash
To determine if there is an overage/ Shortage in the ATM.
To determine if there is cash theft in the ATM machine
