&gt; In a Casino, at some point you have the cold hard cash in your hands. This makes a big difference.<p>That&#x27;s not what i&#x27;ve seen in modern US casinos.  It&#x27;s been a few years, but I remember people using cards for slot machines.  The image I remember most was a man in a wheelchair with his card on a lanyard around his neck.  The card was in the slot machine.  He looked physically tied to the machine, never moving except for one finger on a button.  It looked like something out of the matrix.
