1. All credit cards in China bear the logo of "UnionPay" except the logo of VISA or MASTER, but not abroad, because UnionPay is the only bank card organization approved by the State Council and the People's Bank of China. Moreover, all Kaka backs in China have Chinese profiles, but not abroad.

2. Hong Kong, Macao and Taiwan may also have Chinese profiles. Look at the service hotline on the back of the credit card. If the overseas service hotline is +86, it is a domestic card, because (86) is the international area code of China.

There are only four institutions in the world that can issue credit cards, namely VISA and MASTER, which have the most contacts, and Diners Club (Diners Credit Card) and American Express (American Express Card), which are relatively few.

Although the China Banking Regulatory Commission issued a notice as early as July, stipulating that banks should not charge annual fees before cardholders are activated, many cardholders are still confused about the various rules for handling annual fees with different bank credit cards.

"I have several credit cards from different banks, some of which are free of annual fees for six times, some of which stipulate that the accumulated consumption is more than 5,000 yuan, and some stipulate that 3,000 points are free of annual fees." Ms. Xu, who works in a foreign-funded enterprise, told the reporter that in order to find out the annual fees of different credit cards, she specially called each credit card center to find out, and then wrote it down to avoid the situation that some credit cards would generate annual fees in the following year because the number of swipes or the amount was not up to standard.
