The cards are for the Playstation Store, not the console. If you buy a game for the PS4 on the Playstation Store, you can obviously play it on the PS4.
I believe he was asking if the PS4 would beable to play games you bought through PSN on the PS3, but I think you answerd half the question he ask.. Team Work!
Yeah,you answered half my question, would the ps4 be able to play games bought through psn on ps3
As of now, no.
But they are working on Gaikai streaming, once that is released you should (theoretically) be able to play your digital PS3 titles on your PS4.

can you use psn cards on the ps4? can you play bought psn games on ps4? i bought saints row 2 on my ps3 through psn and i was wondering if i can play it on the ps4.
the psn cards are mostly just value cards to add funds to your wallet, however if there is psn cards made specifically for a game it will only be foir that game and for the platform it is on,,, even for psn games if the game was made to work on the ps3 it will only work on the ps3.. the only psn games you would buy on the ps4 will only be for the ps4.. although i would assume it would also allow you to purchase vita games on it too, but mostly just to allow you to store the game on the ps4 to be later transfered to the vita much like the ps3 does now..
