application loads.

If the Sumcheck Fails

If the sumcheck fails, the following sequence occurs:

Note:

The default read-only message table is copied to the
readable/writeable table area

Note:

A new sumcheck is calculated and stored

Note:

A sumcheck is calculated over the setup parameters

To access the Key Injection mode, select the PF3 key and press Enter.
At the password prompt, enter 67354 (“MSKDI”).

Menu Option Description

Key Index. Menu
Enter Index:

Note:

The index entered here does not over-ride
the index defined by the KeyFac software (KIS
protocol). This index entry is a legacy command
used for systems that previously would not allow
key injection into multiple indexes.

After the index is entered, the unit is ready to accept key injection
commands from the KeyFac system. When each key is injected,
reference the KeyFac screen for messages indicating the completion of
key injection. The NCR 5945 will not display messages as keys are
injected.

KeyFac will issue the “lock” command at the end of each key set
injection.

The Key Injection Mode also directly supports the VISA DUKPT “90” /
“91” Key Load and “76” Test Commands as defined in the VISA
document

Appendix A: Commonly Asked Questions

What is a debit?

A DEBIT transaction is one that results in the direct access to a
cardholder's demand deposit account (DDA). The “credit” transaction
is an electronic extension of an unsecured loan and affects the
consumer's “open to buy.”

A DEBIT CARD is issued by a financial institution and permits the
financial institution's clients to access their DDA by presenting their
debit card at Automated Teller Machines (ATM) and Point of Sale
(POS) locations.

What is the difference between "off-line" and "on-line" debit?

There are two main categories of “off-line” and “on-line” at the POS.
The first category is VISA/MasterCard “off-line” debit. The

transaction in this case is operationally similar to a credit card
transaction. An authorization is received from the processor (e.g., the
merchant is guaranteed funds) and the consumer simply signs the
receipt. The transaction is cleared via an automated clearing house
(ACH), instead of the credit card settlement network. A deferred
reduction in the cardholder's DDA takes place. Today in the US these
transactions are subject to an “interchange” fee.

The second category is an “electronic ACH” where a check cashing
card is used instead of physically writing a check. In this case, a
deferred reduction in the cardholder's DDA takes place but the
merchant is NOT guaranteed payment (unlike the previous category of
“off-line” debit) since the transaction can “bounce” like a check!

A-2 Appendix A: Commonly Asked Questions

An “ON-LINE” debit transaction results in positive identification of
the consumer's DDA AT THE TIME OF THE TRANSACTION. The
consumer is identified by the use of a Personal Identification Number
(PIN) AND THE TRANSACTION IS PROVEN.

In all cases, the amount is deducted from a DDA. In the “off-line”
scenarios the monies are deducted one to three days later. In “on-line”
debit the monies are deducted instantly.

The term “debit” in this document refers to on-line debit.
In order for a merchant to accept debit, the following has to happen:



The terminal software is developed or modified to support debit.



A PINpad is attached for PIN entry.



A printer is required to generate a printed receipt.



Memory is required to store debit transactions. Since check and
cash transactions are typically not stored in the terminal today, and
debit primarily replaces checks and cash, more memory in the
terminal is required to store debit transactions.

What is a PIN?

A PIN is an electronic signature that identifies the cardholder. The
length of the PIN is variable and determined by the issuer of the debit
card but is usually between 4-12 digits in length.

What is a PIN Pad?

As the use of a PIN facilitates access to a DDA and proves a
transaction, the PIN entry process must be very secure. A PINpad is a
device that allows a cardholder to enter the PIN. Its primary function
is to provide a secure means of entering, encrypting and transferring
the PIN to the controlling device (e.g., POS transaction terminal),
which sends the encrypted PIN to the debit processor.

Appendix A: Commonly Asked Questions A-3

What is PIN management?

PIN management refers to the process used to protect the PIN. The
first component is “encryption”, a process used to conceal the PIN and
therefore secure it from fraudulent interception. The result of
encryption is a PIN block that, when received by the bank computer
that verified the PIN, must be “decrypted” prior to processing.
Decryption is a reversal process that is used to obtain the PIN from the
PIN block. The encryption and decryption are done using the Data
Encryption Standard (DES) in the US. Other algorithms are used in
different parts of the world.

PIN verification is on-line in the US. Off-line PIN verification is
usually done in conjunction with a “smart card” and will not be
covered here. One of the prominent countries using off-line PIN
verification is France.

What is Key Management?

Key management is the process to protect the key(s) used in the DES
algorithm.

DES, used in the PIN encryption process, is an algorithm that exists in
the public domain. DES employs a key in the PIN encryption process
and the same key to decrypt the PIN. Since the keys read the

hidden

part of the algorithm, it is critical to protect them. The two methods for
key management used in the US are:

•

Master/session key management system

•

Derived Unique Key Per Transaction (DUKPT)
