Save Point

Save Points are places within worlds that Sora, Riku, and any character that is controlled can save the progress they have made in their travels. Save Points are dispersed throughout the worlds, usually every three or four rooms, as a tracker.

In Kingdom Hearts and Kingdom Hearts II
Save Points are divided into two sections; Permanent and Temporary. Permanent save points will always be there no matter what the situation. they are green colored with a green cricle shining below the character, and a light emiting when you touch them. These save points allow you to use the Gummi Ship, to move to other worlds, and also heal you on contact with them (if you have any health lost that is). It should be noted, that save points does not reload drive gauge.

Temporare save points have a green swirly shape hovering above the ground. You cannot access the Gummi Ship, you are healed, and more than likely these will be gone after the next cutscene. These are normally used before boss battles.

The save points in Kingdom Hearts II are sometimes unable to be accessed, because of story plot. Sometimes, they cannot be accessed by Gummi Ship, even after the end of the story, so you have to find them on foot, and then they will be restored.

In Kingdom Hearts: Chain of Memories
In Chain of Memories, save points are accessed through a card known as "Moment's Reprieve". They can be used in any room except for story and boss rooms. Save points are also found on each floor of Castle Oblivion

Gummi Ship
In Kingdom Hearts II, Gummi Ships can be use as Save Points, just by pressing Start, and Saving Progress.
