Many people know that EMV and PBOC are two different standards, the foreign card is EMV standard and UnionPay card is PBOC standard.
EMV is a chip card standard from EMVCo (International Organization for Standardization of Chip Cards), which was jointly founded by Europay, MasterCard and V is a, and Europay was later acquired by MasterCard. In fact, EMV standard is the world's actual financial IC card standard jointly formulated by the two largest card organizations in the world.
PBOC actually refers to the People's Bank of China (China), so this standard is issued by the Central Bank of China-in fact, this is also an example of technology introduction to independent research and development-and most of the underlying technical details of the standard are basically copies of the EMV standard.
Therefore, PBOC is developed by the central bank, and UnionPay is naturally attached to it. Therefore, IC chip cards issued in China are basically PBOC standards, while EMV standard cards are VISA or MasterCard single-label credit cards.
Conclusion: Personally, I will choose PBOC chip cards for domestic transactions and VISA and MasterCard chip cards for overseas transactions.
CCB's card processing speed in official website is still relatively fast.
