The cardswap is the effort by B3V & DN to switch out the access cards used by subscriber boxes. The cards they are replacing are nagra 2 cards and are being replaced with new Nagra3 cards, also referred to as the ROM240 (B3V), ROM241 (DN). The new DN cards are sometimes referred to as "G3" cards since G3 is on the front of them.
