Any simple checksum methods for CC receipts with tip?

How many restaurants still use this ancient method with CC’s?

Whenever I use a CC in a restaurant the waiter brings the CC machine to the table and I key in the tip. It then prints out the receipt showing the bill, tip and total.

So the restaurant never gets hold of my card and I can see that everything’s correct.

Granted that I don’t go out all that often, but I have never once been to a place that did this.

I think that all you need to do is ask and they will bring the CC machine. That is what we do here in Bogota, Colombia
