New Vegas passport

A passport is a miscellaneous item in Fallout: New Vegas.

Characteristics
You use it to get into the New Vegas Strip, and possibly other places. This can be obtained by completing G.I. Blues quests for the Kings located in Freeside. On completion of the quest The King gives you a couple options for a reward, one of them is to get a free passport at Mick and Ralph's store located by Freeside's East Gate, otherwise the passport is 500 caps. If you have a high enough barter skill, there is an option when talking to Ralph to lower the price to 375 caps.

However, the player can still get into the Strip as long as he or she can pass the credit check of 2000 caps (Note that this does not mean that you lose your caps, you just need to have to be carrying 2000 caps).

Note: A passport is not required if you enter the strip via the monorail at the NCR Camp McCarran or if you have Science above 80, in this case you can convince the Robot to allow your entrance.
