Thank you so much for playing my game :p!!!
May I ask what about the code made you confused? I'd like to make updates to the puzzle, like maybe a third hint, and I think your insight would be very helpful!

I am just genuinely not into puzzles. So maybe not the best case to optimize for.
But one hurdle was not being sure if the system is case sensitive.
My best guess was S52TG1
I don't know where the F is coming from. I couldn't tell what the letter on the second card was supposed to be so that put an hard stop at further progress.
