The same four cards in the three layouts. Mobile is one big index and one big suit, with no second corner — the card to deal when several are fanned on a phone. Standard is the card as it is printed: two corners, and a true count of pips in the arrangement a real deck uses. Jumbo index is that with the corners at about twice the size, and the pips squeezed to pay for it.
Drag the size down and watch which of the three is still a card. That is the whole argument for the mobile face, and the whole argument against it at any size a card is actually dealt at on a table.
