Credit cards are different from credit cards in terms of functions, deposits, interest-free periods and relationships, as follows:

1. Functions: Credit cards have some functions of debit cards, but credit cards don't.

2. Deposit: Credit card deposit bears interest (calculated at current interest rate), but credit card deposit does not bear interest.

3. Interest-free period: Credit cards do not enjoy an interest-free repayment period, while credit cards can enjoy an interest-free repayment period of 25 days at the shortest and 56 days at the longest.

4. Relationship: The most essential difference between credit cards and credit cards is that credit cards and credit cards are actually inclusive.
