"That just sounds like Sure Gamble with extra steps".
Falsified Credentials is a strong card that fills an interesting design space. Exposing has never been a fully explored mechanic but now with the release of 419, it will definitely be all over the meta for a while. At the very worst of times, this is an Infiltration for 1 credit, which is bad but not nearly as bad it sounds. NGO Front is everywhere nowadays and with the rise of 5-3 agendas, knowing if that advanced card in the remote is worth running or not, is invaluable info to have.
But that's the worst case scenario, outside of exposing a Psychic Field. If you guess correctly, you gain 5 credits, which is a Sure Gamble level return. And we all know how strong that card is. So you will obviously want to guess correctly. In 419 or Silhouette decks this card is obviously bonkers, as you will be able to guess with enormous accuracy. Not only that, but this card combos extremely well with Aumakua, giving you a virus counter regardless of your guess. But even if you don't play an expose oriented deck, if you have some knowledge about the kind of cards your opponent would play in their ID, you can still make an educated guess and be rewarded for it.
Does that make it worth the influence in non-criminal decks? Probably not, but it is definitely a great card to have in the pool and it can be extremely powerful in the hands of a player with meta knowledge.
