I'm trying to think the last time I saw one in use, last year or a couple years ago when there were large scale power outages. Of course the newer cards lack raised digits so I'm not sure how well they worked for keeping business moving. I had cash.
As I recall, the slips do have a spot where you can just write the numbers down. But widespread lack of raised numbers makes them hard to use. I think all my cards have been reissued flat by now.
