Hand Scanner

Hand Scanner
Hand Scanners are devices that appeared only in Metroid Prime 3: Corruption. They require the player to stand in front of the terminal and press A to initiate a palm scan to activate a device such as a door. They are featured on the GFS Olympus, Elysia and the Pirate Homeworld. There is one on Norion. They do not appear on Bryyo and are instead replaced by other devices such as pumps etc. Hand Scanners are often used for activating lifts and doors. They supposedly work like a finger print scan to identify the   person activating the device to check if they are authorized. However, the Pirate Homeworld scanners require the user to have three fingers to be placed into an indent. But when Samus activates them she places her entire hand on the device not necessarily on the three fingers and the device still activates. This may be because her suit is able to hack the scanner or it may simply be a button. The logic works on the first two Hand Scanners because the GF design is able to identify her as a GF Bounty Hunter. And on the Chozo design of Hand Scanner the scanner allows operation because Samus has Chozo-infused blood, or siply she has a Chozo suit.
