There's such a field where the numbers are in there I scratched it but you can't see a few numbers now what can I do
I had the same problem, I panicked completely because I thought I had put 50 euro in the sand. I did it back then, just called support and they wanted to know a few other numbers on the card and then they gave me the number for the card.
The best thing to do is to simply call PlayStation's free hotline tomorrow and describe your problem.
Try guessing them or call PlayStation Support or something
Often, the numbers are also stamped lightly - if you hold the card diagonally against the light, you may recognize the missing numbers by the shadow cast.
Otherwise contact PS Support, they can tell you the code via the card number.
