Credit cards for premium access

Is it safe to use personal credit cards to purchase premium access? I have (3) cards- 2 credit cards and also a debit card from my bank. If I used them would it reveal my personal info to the site admins? I have only used my two credit cards to purchase viagra and pay for my phone bill. Thanks.

What's funny is I was able to recover his numbers from those images. lol

Anyone need some gas?
