Changes to ATM machines

What I remember about casino ATMs in Vegas is that you swipe the card using your hand, only, so the card is always in your hand and is never out of your possession. In other words, the card is never inserted into a casino ATM where it could get stuck or be forgotten. Am I correct about this?

In the "Open" forum I wrote about a change in the procedure for using Bank of America's ATMs. I know that there is a problem with customers forgetting their ATM cards when they insert them into machines.

Update: There is a security feature with the new B of A system that will stop someone from doing a piggy-back transaction. I posted this on the "Open Forum."

So now the question is, are there security flaws with the Vegas ATMs?
