i need some help

I asked my dad to give me a credit card but instead, he gave me a visa with his name because I'm too young and it was much useful and every time I buy something online they would send my dad a code and he would send it back to me and I noticed that the store name isn't written in the code so I thought that I can now purchase from lezhin and support them, and I already bought some coins but now I'm so anxious if he could see where I spent the money especially that my parents are so strict if they know I would be dead, so is there a way for him to see my purchase history in he's account?
