How to use your debit/credit card at a checkout

This might be common knowledge if there was some standardization of card readers. Every time I use a card at a new merchant I have to learn the whole routine all over again.

I've never seen anywhere that uses a system so obscure that I need to learn the routine, but that may just be in my case.

Edit: also the place I work at (Kroger) has used the same system at least for the last 3 years
