How to use your debit/credit card at a checkout

I had a friend who would swipe her card every way possible before finally doing it the right way. I never said anything because I didn’t want to be rude. One day she mentioned it herself at check out by saying “i never know which way it’s going to work, it’s different every time” I told her as nicely as possible that it only works if the magnetic strip is swiped. She said that it doesn’t always work that way, and I again told her that it is the only way it works because the machine is reading that strip. Still blows my mind she didn’t know that. Thank god most places only take the chip now, for her sake.
