The Member Card grants the player access to the Harbor Inn in Canalave City. Shortly after, the player will meet a strange old man, have a nightmare, and travel to Newmoon Island, where Darkrai can be obtained. If Darkrai is obtained, a booming voice will talk to the player and the player will wake up from their nightmare with Darkrai either in their party or in the PC. The player can rebattle Darkrai again, if fled from or fainted.
Before the player may enter the Harbor Inn using the Member Card, the player must first meet Cresselia, obtain the Lunar Wing, and use it to dispel the nightmares Darkrai inflicts on Eldritch's son.
For more info on how to get DARKRAI, visit the official Pokémon website. Be sure to save your game after you pick up the Member Card at a Poké Mart.

Trivia
Before official distribution, the Member Card featured many different names including: Member's Card, Membership Pass, Member's Pass, etc. until it was revealed to officially be called the Member Card.
In the Member Card's description, it says that the last date marked on it was 50 years ago. On the official artwork, it is labeled "1958.12.1", exactly 50 years before the first Japanese distribution.
When receiving it from the man in the Poké Mart, it will display its name as "Member's Card", though in the Bag, it is simply "Member Card".
The Member Card opening the door of an inn is somewhat similar to the way some hotels today use key cards for room access.
