Does anyone know how to do this card trick?

There is one audience member, and two magicians. One magician turns his back while the audience member picks one of six cards laid out on the table in a 2x3 formation. The other magician turns around. The magician who knows will point to cards randomly and ask "was it this one" and at some point will point at your card and the other Marian will say "yes" after being asked. He does touch the cards and usually picks three before getting to yours but not always. Also, they were able to flip the cards over and still do it.
