My company had them on-hand until around 2021, when I told everyone to throw them out. They'd last been used - at one location, during a complete POS meltdown (I don't miss Aloha at all) - in maybe 2018? No one could remember a previous time.
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.
