Anyone can get into and out of the Ghost Zone with it. It also serve as an address book/map "for a bazillion ghosts". The map also changes as the ghost zone changes.
In "Infinite Realms," after Danny, Sam, and Tucker crash the Specter Speeder in the Far Frozen, they end up stranded in the Ghost Zone with no way home. Frostbite offers to aid them by lending them the Infi-map.
However, Danny accidentally activates the map which brings him, Sam, and Tucker back to Fenton Works. Vlad, via a hidden surveillance camera, sees them with the Infi-map. Danny, Sam, and Tucker use the map to take a tour of the Ghost Zone, but lose the map to Vlad.
Vlad then commands the Infi-map to take him to his destiny, sending them on a chase throughout history. Eventually, the map leads Vlad back to the Realm of the Far Frozen where the map is returned to the care of Frostbite and his race.
At the beginning of "Phantom Planet," Danny fights Vlad to take back the Infi-map, which Vlad stole from Frostbite before the beginning of the episode. Near the end of the episode, Danny uses the Infi-map when exploring the Ghost Zone looking for aid.
The Infi-map itself resembles and appears as a scroll. When touched, it can project a hologram of a map of doors.
- Telepathy: It first displayed by the Infi-map, however, it needs to make tactical contact to be able to do so. Clothing does not act as a barrier to this version of the ability, meaning the Infi-map does not need skin-to-skin contact to make an telepathic connection, only the close proximity of touch.
- Transportation: The map can transport users to locations in the Ghost Zone. The Map can also transport a person to their destiny.
- Portal Locating/Location: The Map can locate any natural or artificial portal in the Ghost Zone take it user to the human realm, but some portals also lead to different places in time.
- Door Projection: When someone opens the map, it project a series of hologram doors. This was shown in "Infinite Realms," when Frostbite shows the Infi-map to the trio as it projects a series of holographic purple doors when showing different possible locations to go to.
