User Defined Modulus Check Program (E94)

Purpose: Use this screen to define the program name used to validate credit card numbers entered for credit card pay types defined with an MU modulus check.

System name field: Enter the user-defined program name used to validate credit card numbers entered for credit card pay types defined with an MU (modulus user) modulus check. A modulus check performs a calculation against the digits of the credit card number to ensure that the card is valid.

Leave this field blank if you do not want to define an MU modulus check for a credit card pay type. The screen in Work with Pay Types displays an error message if you enter MU in the Modulus check field:

Modulus check program has not been specified for SCV E94.
