StarPets Asking for Full Card Details Feels Unsafe for Payments

I wanted to make an in‑game purchase on StarPets to buy a pet, but I became very hesitant when I saw that the system directly asks for my full card details. I have not entered my card information or completed any payment yet, because I am worried about the safety of my funds and do not find it reassuring that card details are requested in this way. I am wondering why StarPets asks users to enter their card details directly instead of offering safer and more familiar payment methods or providing clear and detailed information about payment security. I request a clear explanation on this issue and more transparent information about how card data is protected, so that users can make purchases without worrying about the security of their money.
