When traveling to France, should I use a credit card, UnionPay or VisaMastercard?

If you use a credit card when traveling to France, you must use visa or mastercard.

Because visa and mastercard are global credit card organizations and are more suitable for use across the country, UnionPay is a bank card issuer in China and is a state-owned institution. It not only issues credit cards but also debit cards. , most of its product coverage is in China, so it is not feasible to use it in France. Moreover, from the perspective of issuance area, visa and mastercard belong to American card organizations.
