No, you can't get a credit card at 17 as you aren't allowed to enter into a legally binding contract (the Credit Act) until you are 18.
Under 18s can obtain other types of bank cards that draw directly from funds within their savings or current accounts. These are called debit cards and are accepted in just as many places as credit cards are. The only difference is that you can only spend what you have in your account. They don't extend you credit in the way that a credit card does.
