Bank Card Two-Factor Batch Verification

Tool Introduction

The Bank Card Two-Factor Batch Verification tool is an efficient and practical online service designed to help users quickly verify the matching relationship between a large number of bank card numbers and cardholder names. In scenarios such as financial risk control, identity verification, user real-name registration, and payment channel management, ensuring the authenticity and validity of bank card information is crucial. This tool allows users to input the cardholder's name and corresponding bank card number, and the system will automatically compare the data and instantly provide verification results, including whether the name and card number match, and whether the card number is valid.

Principle of Bank Card Two-Factor Verification

Bank card two-factor verification is implemented based on interface services provided by bank systems or third-party certification agencies. When a user submits a name and bank card number, the system sends this information to the backend, which then compares it with the bank's core database through a secure encrypted channel. The verification process confirms whether the submitted name is exactly consistent with the account opening name registered with the bank card, ensuring that the bank card number indeed belongs to that name. This verification method is one of the important means to ensure the security of financial transactions, prevent fraud, and achieve user real-name authentication.
