UnionPay card consumption abroad: In overseas countries, cardholders can still confirm their consumption by password if they choose to use UnionPay card. However, if some UnionPay merchants do not support password confirmation, the cardholder only needs to sign to confirm the transaction. Therefore, everyone should form a good habit and sign their names on the back of the card as soon as they get the credit card application.
Visa/MasterCard: Select Visa/MasterCard to swipe the card online, and automatically sign to confirm the consumption, without entering a password.
Finally, the website reminds cardholders once again that after getting a credit card, don't just focus on activating the card and ignore the credit card endorsement. Because overseas credit card consumption only needs to check the signature, if the cardholder does not sign back, it will affect his normal consumption abroad. So, remember to sign when you activate the card.
