Agreed, the terminology is "on card" means pack issued without a sticker auto, as in, the player actually held the card itself and autographed it.

"Sticker" auto is manufacturer released with a sticker signed by the player affixed by the company. Players get sent pages of stickers and never actually touch the cards themselves.

"Captured" auto is when something like a cardboard/index fragment is signed and installed into the card.

You're mainly talking about "Through the mail" or "In Person" (TTM/IP) autos; cards that are signed by the player after they've been released unsigned. COMC calls them "aftermarket" autos.
