At present, Bank of China, Industrial and Commercial Bank of China and Guangdong Development Bank have cooperated with two international credit card organizations, VISA and MasterCard, and launched three global bank cards, namely, China Bank Great Wall International Card, China Industrial and Commercial Bank Peony International Card and Guangdong Development Bank Foreign Exchange Card. The three international cards used now can be subdivided into debit cards and credit cards. Their main differences are:

International debit card holders must open a foreign exchange account or deposit a certain amount of reserve fund in the bank in advance. After spending abroad, the bank will deduct the account from the card, and the cardholder cannot overdraw. The application processing time is generally 3 to 10 days.
