That's my understanding as well.  My wife runs her own business and has a
chip reader from Square.  She says it works fine, the only thing is you
have to keep the card in the reader while the customer signs it, and it
takes longer than swiping the card.

I believe the chip card was created to prevent things like that from
happening.  The electromagnetic strip that still exists on the back of chip
cards is still vulnerable to that, though.  That may be what they're
talking about.
