the so-called "three relatives" means that when handling credit cards, the issuing bank needs to see the person in person, the original application form and the signature in person. Article 38 of the Measures for the Supervision and Administration of Credit Card Business of Commercial Banks issued by the banking regulatory authority stipulates: "The issuing bank shall openly and clearly inform the applicant of the application materials and basic requirements to be submitted, and the applicant must personally sign the application materials, and shall not issue credit cards in a way that the customer is unaware of or does not meet the customer's wishes."
Therefore, the "three relatives" of credit card refers to the "three relatives" principle implemented by the issuing bank to credit card applicants, which is mainly to prevent criminals from applying for credit cards under false names, reduce the risk of bank credit card business and protect the personal rights and interests of credit card applicants from being infringed.
