how do credit card details typically get imported into NS? having an excel sheet of all the credit card info and having that info available to everyone who has access to csv import status page will mean everyone can see CC info. Is there no PCI compliant way to do this?

@shamwow19 CSV import permission is a huge, glaring control deficiency that I've brought up many times, and the only answer I've ever gotten is "limit access to CSV imports". Side note: if you import records successfully, the CSV response file actually wouldn't show the details, it will just say "XXX records imported successfully".

They also disappear after 30 days

If there are no errors, you wont see the details. The issue will be if there are any errors, user will be able to see the data of the records that failed.
