When businesses need to verify the authenticity and validity of a user's bank card, this tool cross-references three key elements: the user's name, bank card number, and ID number. This verification method relies on cardholder information recorded in the banking system, ensuring that the input data matches the bank's official records before returning a successful verification result.
You can verify a maximum of 100 records per request. The ID number must be a valid 18-digit number. Verification results are for reference only, and the bank system's official records shall prevail. Please ensure the strict protection of user privacy and data security.
We recommend that businesses implement this verification during critical stages such as user registration and transaction confirmation. Typical use cases include e-commerce platforms verifying buyer identities, peer-to-peer (P2P) lending platforms verifying lender information, and financial institutions validating account opening documents. Example input: "John Doe,6228480402564890018,110101199003072396". A successful match will display "Information Matches".
