Poseidon Energy employee ID card

 is a miscellaneous item in Fallout: New Vegas.

Characteristics
Similar in appearance to holotapes, two of them are found during the quest That Lucky Old Sun.

Locations
Two are located in HELIOS One, in the solar collection tower. They are past the Mister Gutsy. At the bottom of the multi-leveled stairwell, turn south, away from the protectron, then east into the room. They are in the southern end of the room, on the floor near a skeleton and some desks.

Uses
can be used to activate a repair robot in the solar collection tower to complete the That Lucky Old Sun quest, which is necessary if your repair skill is insufficient to do the repairs yourself.
