Pass Card

Pass cards are items that are randomly dropped by ghouls or centaurs. There are no places where a pass is guaranteed to be found. A ghoul has a 1 in 80 chance of dropping a pass of either color; for a centaur the chance is about 1 in 170. The cards have no purpose.

In Fallout 1 and 2, Red, Blue, and Yellow pass cards were also used to open corresponding doors, and their presence here may be a nod to the preceding games in the series, Which in turn may be a nod to DOOM, one of the first first person shooter games ever created.
