Yes. You can imprint the card and/or record the information for offline processing. We had credit cards before everyone had internet access.

Heh, I had forgotten about those card imprint machines! Think I used one 2 times in one of my first jobs.

Those technically exist, but who still has them? Are they even still allowed with modern credit card agreements?

What about the percentage of people who no longer carry physical cards and rely on a smartphone/smartwatch credit system?
