I've had a bank account in my name since I was born, but I didn't get my first card until I was 13. It was a Visa Electron cashcard and, while they don't exist in many jurisdictions any more, it allowed me to deposit money into an account and withdraw it from an ATM; I couldn't use the card directly in purchases, but I was still happy. That got upgraded to a Debit card when I was 16, and then I got a credit card - never been used! - to go with it when I turned 18. For the most part, I use my Debit card for everything: even piddly purchases like buying milk from the supermarket. Living in a large city, nearly everywhere takes card, so I'm not worse off. Also, if I have cash, I feel strangely obligated to spend it all straight away, so the card is a very good way of curbing my occasionally excessive spending habits.
