Debit card is a kind of bank card issued by financial institutions, which is associated with the cardholder's debit account. Simply put, it is how much money to save and how much money to use, and you can't overdraw. Debit cards can be divided into online debit cards and offline debit cards. The former is the so-called electronic debit card, which should be used online at any time and the account can be deducted immediately. All transactions are conducted through passwords. The latter supports credit card transactions and background payment requests. Some transactions (especially consumption) do not need a password, which has certain transaction risks. At present, it is rare in China. Some international debit cards issued by banks are offline debit cards (such as Minsheng International Debit Card) in order to be in line with international standards. However, these cards are treated as electronic debit cards in China, just like domestic debit cards (such as Great Wall Electronic Debit Card and Peony Link Card).
The definition of savings card is different at home and abroad. Domestic savings cards (such as Dragon Card Savings Card and Postal Green Card Savings Card) are electronic debit cards. In foreign countries, savings cards are generally equivalent to ATM cards, which are connected to savings accounts and cannot be used for consumption.
Credit cards are debit cards, and the most direct difference between them is that they can be overdrawn. Of course, there are also quite complicated differences in technology.
Whether the debit card can be paid online depends on whether the bank supports it. Debit cards of most banks can be paid online now. In addition, pay attention to see if your payment gateway accepts your card.
