An IS auditor recommends that an initial validation control
be programmed into a credit card transaction capture
application. The initial validation process would MOST likely:
A. check to ensure the type of transaction is valid for that
card type.

the database.

cardholder's credit limit.

Answer / guest
Answer: B
The initial validation should confirm whether the card is
valid. This validity is established through the card number
and PIN entered by the user. Based on this initial
validation, all other validations will proceed. A validation
control in data capture will ensure that the data entered is
valid (i.e., it can be processed by the system). If the data
captured in the initial validation is not valid (if the card
number or PIN do not match with the database), then the card
will be rejected or captured per the controls in place. Once
initial validation is completed, then other validations
specific to the card and cardholder would be performed.
