For specific reasons, first of all, let’s popularize the EMV standards and PBOC standards of chip cards . Many people know that EMV and PBOC are two different standards. The wild card is the EMV standard, and the UnionPay card is the PBOC standard.

EMV is a chip card standard from EMVCo (International Chip Card Standardization Organization). It was founded by Europay, MasterCard and Visa. Europay was later acquired by MasterCard. In fact, the EMV standard is the world's two largest cards. The world's actual financial IC card standard co-founded by the organization

PBOC actually refers to The People's Bank of China (People's Bank of China), so this standard is issued by the Central Bank of China - in fact, this is An example of transitioning from technology introduction to independent research and development - most of the underlying technical details of the standard are basically copies of the EMV standard.

Therefore, PBOC was developed by the central bank, and UnionPay is naturally closely attached to it. Therefore, the IC chip cards issued in China basically use the PBOC standard, which is applied to UnionPay single-logo cards, while EMV standard cards All are VISA or MasterCard single logo credit cards.
