MPChat encourages users to practice safe card usage and advises against disclosing important card information—card number, expiration date, and CVV—to anyone, or inputting card details on unsecured websites. In the event of a fraudulent charge, MPChat suggests users take the following measures:
Freeze the Card: Immediately log in to the MPChat app and freeze the card. Operation path: MPChat app → Card → Freeze. A friendly reminder: before freezing, it is recommended that you first unlink the card on the merchant's side to avoid rejected transactions and potential fees.
