How can I obtain a debit card if I am under 18 years old without involving my parents?

To obtain a debit card if you are under 18 without involving your parents, you can look into opening a joint account with a trusted adult who is willing to help you manage the account. Some banks and credit unions offer accounts specifically designed for minors that may allow you to have a debit card with a joint account holder. Be sure to research the options available to you and understand the terms and conditions before proceeding.
