How does a debit card work?

A debit card can be used for payments in stores, online, using your phone or watch, and for ATM withdrawals. No credit check is required, making it available to people with no income, and at many banks, even to teenagers with a youth account, with parental consent.
How does a credit card work?
Credit card has a revolving credit limit. The bank provides it after assessing your creditworthiness (income, expenses, and credit history). When you pay with the card, you use the bank's funds; after the limit is repaid, it becomes fully available again.
The card operates on billing cycles. After each cycle, the bank sends a statement of transactions and sets a repayment date. Interest-free period covers the billing cycle and repayment period—depending on the bank, it usually lasts about 50–60 days. If you pay off the entire balance by cashless payments on time, no interest will accrue. You can also make only minimum payment, indicated in the statement, but in this case the bank will charge interest on the remaining amount at the card's interest rate.
