I don't think the age verification systems used online will accept a debit card though and I don't think you can get a real credit card under 18 even with a parent authorizing or co-signing. Even though a debit card acts like a credit card under most circumstances where your available balance is effectively your "credit" limit but there are ways of telling the difference between a debit/check card and a real credit card.
