Splat, what you need is a visa/mastercard giftcard from any of your local grocery store, however the difference between that and an actual online debit or credit card is simple: Debt.
When you start owing the bank cash, the government will step in, and when they see that you're using your government issued cheques for this purpose, you'll be in deep shit. Really deep shit.
Bankruptcy will lead you to lose all of your possessions to make up whatever debt you owe the bank and/or government. Not only that, your guardians, such as your sister, mother, or whoever who looks after you will suffer as well. They may even lose their homes if you decide to go completely overboard. If they lose their homes, you will have no choice but to either go A: Homeless, or B: Take shelter at a government owned care facility where they lock you up like an animal.
Play it safe, go to a store, buy a 25$ visa or mastercard, not vanilla though, they suck, or have your sister find you a refillable giftcard from a local bank.
