I just installed cryptopay swipers and tap on my wash select 2, I was using Unitec's sierra site server to keep track of everything. I was able to create codes and program coupons to be used on the wash select for free washes and discounts. Is there a way to keep using the sierra site server and the cryptopay together, so that I can keep using the codes and coupons? or are there ways to program the wash select 2 itself to accept coupons for the mars bill validators?
