Are you talking about an ordinary bank debit card? As long as it is not a credit card, 16 years old can do it. I just need to take my ID card to the outlet. /kloc-under 0/6 years old, the guardian is required to handle it together. Bring the guardian's ID card and household registration book to the bank outlet. If you want to apply for a credit card (that is, a card that can be overdrawn), you need to be at least 18 years old, have a fixed job, and need my ID card and income proof and other relevant information before you can apply.
