Bank Card Extractor

Tool Introduction

The Bank Card Extractor is an efficient and convenient online tool designed to help users quickly query and verify bank card information. Based on the bank card number (or BIN code) you enter, it can instantly identify key information such as the issuing bank, country/region, card organization, and card type (e.g., debit card, credit card), and supports Luhn algorithm to verify the validity of the card number. This tool is particularly suitable for developers to perform payment system testing, risk control system pre-warning, and preliminary verification of user input information.

How to Use

1. Paste or manually enter the bank card number you need to query or verify into the input box.
2. Click the "Query/Verify" button.
3. The system will instantly process and display the query results.

Input Parameter Requirements:

• Supports entering a complete 13-19 digit bank card number.
• Also supports entering only the first 6-8 digits of the bank card number (i.e., BIN code) for basic information queries.

Output Result Format:

The query results will be displayed in a clear and concise list format, including but not limited to the following information:

• Luhn algorithm verification result: whether the verification passed (valid/invalid)
• Card type: debit card, credit card, prepaid card, etc.
• Card organization: Visa, MasterCard, China UnionPay, JCB, American Express, Discover, etc.
• Issuing bank name: e.g., Industrial and Commercial Bank of China, China Merchants Bank, etc.
• Issuing bank's country/region: country, province, city
• Bank Identification Number (BIN): first 6-8 digits of the card number

Frequently Asked Questions

• Q: What bank card types and card organizations does this tool support? A: This tool supports mainstream bank card types globally, including debit cards, credit cards, etc., as well as major international and domestic card organizations such as Visa, MasterCard, China UnionPay, JCB, American Express, and Discover.
• Q: What is Luhn algorithm verification? Can it guarantee that the card number actually exists? A: The Luhn algorithm is a checksum algorithm primarily used to verify the validity of digital sequences such as bank card numbers and IMEI numbers, and can quickly identify most input errors. However, it can only verify format validity and cannot guarantee that the card number actually exists or has transaction capability.
• Q: I only know the first few digits of the bank card number (BIN), can I query it? A: Of course! By entering the first 6-8 digits of the BIN code, this tool can still query basic information such as the issuing bank, card organization, and card type for you.
• Q: Will this tool store the bank card numbers I enter? A: Please rest assured, the Bank Card Extractor only performs real-time queries and verifications when you use it, and will never store, record, or disclose any bank card number information you enter. We are committed to protecting your data privacy and security.

In-depth Analysis of Bank Card BIN Code

What is a Bank Card BIN Code?

A Bank Card BIN (Bank Identification Number) is the first few digits of a bank card number. It is usually 6, 8, or more digits. It is a standard set by the International Organization for Standardization (ISO) to identify the issuing institution. Different banks and different card types have different BIN codes.

What is the purpose of a BIN code?

• Identify the Issuing Institution: The most direct function is to identify which bank issued the card.
• Distinguish Card Types: It can distinguish between debit cards and credit cards, as well as the card's level (standard, gold, platinum, etc.).
• Identify Card Organization: Determine which international card organization issued the card, such as Visa, MasterCard, China UnionPay, JCB, American Express.
• Identify Issuing Country and Region: The prefix of the BIN code is usually associated with the country code, which can help determine the issuing country and region of the bank card.
• Risk Control and Security: In payment and transaction processing, the BIN code is an important basis for risk control, fraud identification, and routing decisions.

Through the Bank Card Extractor, you can quickly obtain the rich information contained behind these BIN codes, thereby making more informed judgments in various scenarios.

Notes

• Please be sure to enter the correct bank card number or BIN code; incorrect input may lead to query failure or inaccurate results.
• This tool provides information query and validity verification services and does not involve any financial transaction functions (such as balance inquiry, transfer, top-up, etc.).
• Our BIN database is updated regularly, but given the frequent changes in global bank card information, there may be a short delay for information on a few newly issued cards or niche bank card BINs.
• This tool is for learning, testing, and auxiliary purposes only. It is strictly prohibited to use it for any illegal, fraudulent, or privacy-infringing activities. Please comply with relevant laws and regulations.
