Credit card interest is similar, almost 20%. There is no interest on deposits. Credit card accounts consume money, not deposits, and need to pay an annual fee, but many credit cards are exempt from annual fees as long as they spend a certain amount.
Students need RP to apply for a separate credit card (that is, not a visa debit card). If you work, you can basically apply with a salary slip, but it seems that the overdraft does not exceed 1500. After all, banks are not very worried about international students.
