Shift4 PMS / POS Setup (Other Settings)

---

If this is a new install, a customer that's never had Shift4 or your Shift4 install hasn't been updated in years, you MUST run the program for credit card number masking, "MENUS4MK". You must run this program to properly mask existing card numbers and prevent entry of unmasked card numbers in the future. It's run using Run Program By Name

Enable Shift4 as the Credit / Debit Card Processor

• Open the text file, menucard.fil,with Notepad or any other text editor.
  This file is found in the software installation folder.
• The first line should be as follows:
  
  S4
  If it's already there, but there is a character in front of it, remove that character.
• After ensuring that this has been done properly, save the file.
