American Express in Mexico has developed their own loyalty program called Payback. Members gain loyalty points when they use their membership number on transactions. Payback membership numbers are issued in one of two ways:

  • A separate Payback membership card can be issued. This card can be swiped in RA Open when the cursor is in the Frequent Traveler field in the AD Subwindow.
  • The membership number can be embedded in the magnetic stripe of the renter's American Express Card.
Refer to the chapter Overview - American Express Payback Program for details on how the Payback program logic in CARS+ works.


This program is used to enter control data for:

  • defining settings for processing Payback rentals
  • transmitting Payback data to American Express

To access the Edit Payback Control Record program, type EDTPBC (RET) at any menu "OPTION:" field or the appropriate line number on the Hertz Mexico menu. The screen will then display:

Set up required:

In addition to the control files mentioned at the beginning of this chapter, the following set up is also needed to use the Payback logic.

A. A cell phone number must be entered when opening Payback rental agreements. A field in Edit Misc. Control Fields is used to turn on that requirement.

B. The Frequent Traveler Code "PB" must be set up in Edit Frequent Traveler Codes an Edit Frequent Traveler Program Dates.

C. Enter the Frequent Traveler Code (PB) in the "Payback" field in Edit Card Definitions for the BIN ranges of American Express cards that have a Payback membership number embedded in the magnetic stripe (not all AX card ranges support Payback).


USER TIPS: The following describes how an American Express card with a Payback membership number is used in RA Open:

  • If the card is swiped as the presigned FOP for the rental and there is currently no Frequent Travel Code on the transaction, the payback membership number will be added to the RA without any message.
  • If the card is swiped as the presigned FOP for the rental and there currently IS a Frequent Travel Code on the transaction, the following question will be asked:

SHALL I REPLACE YOUR FREQUENT FLIER # WITH YOUR PAYBACK #? Y/N

If the counter agent answers "Y" the Payback membership # will replace the Frequent Traveler number currently on the RA

If the counter agent answers "N", the AX card number will be placed on the RA as the presigned FOP but the Payback membership number will NOT be added.

  • If the American Express Card is swiped when the cursor is in the Frequent Traveler Code field of the AD Subwindow, the Payback membership will be added to the transaction BUT the American Express FOP will NOT be added to the RA.
