The fields in this panel enable you to configure the terminal to request additional invoice related data when authorizing a card; an example of additional data might be an invoice number, which is required for MO/TO merchants:

• Number Keys: The 9-character entry in this field specifies which keys (identified by their position in the 9-character entry) will prompt for additional data, using the characters Y (for the key of that position to prompt) and N (for the key of that position not to prompt). When this field is enabled, it defaults to NNNNNNNNN. Positions 1-9 correspond to terminal keys as follows:
  • 1: Purchase or Mail/Phone Order (1 key)
  • 2: Purchase or Mail/Phone Order (2 key)
  • 3: Reserved - not used (3 key)
  • 4: Credit (4 key)
  • 5: Auth Only (5 key)
  • 6: Offline (6 key)
  • 7: Reserved - not used (7 key)
  • 8: Private Label (8 key)
  • 9: Reserved - not used (9 key)

  Number Flag: When selected, this check box enables the terminal to issue the prompt Enter Invoice Number on transactions.

  Note: The Number Flag check box MUST be selected if the merchant is processing MO/TO (Mail Order/Phone Order) transactions.

• Prompt: The entry in this field indicates the text that will display when any of the Invoice Number Keys listed in the Number Keys field in this panel are set to Y.

  Note: This field only becomes available if at least one of the Invoice Number Keys in the Number Keys field in this panel is set to Y.
