Do you want to be able to sort your customer lists in a unique way? You have some flexibility in how you are able to sort your data in Punchpass.
We recommend using the City field, which is shown on the View Customers page as your 'Wildcard' field. Most customers do not use the address fields in Punchpass - probably because very few people actually mail something anymore!
Instead, you can put other pieces of information in that field and then use the search box in the customer list to narrow down your list.
