[Alien Isolation] What are the save points?

For the player, it's a place to save progress but I'm curious what it is in-universe. It's a panel with a phone that you insert a flash drive into, but I don't really know what it does.

The card that Amanda slides into the phone acts as an identity card.  The universe in which Weyland-Yutani and Lorenz Systech exists apparently never developed miniaturized Common Access Card technology so identity cards are large and bulky to hold all the personal data needed on such a card.
