What's a bank card validation tool?
Bank Card Validation ToolIt's a free online tool to help you quickly verify whether the bank card number is correct. This tool allows for the identification of bank card validity, card type and card-line information using the internationally common Luhn algorithm.
Validation of bank card numbers, whether in online shopping, money transfers or other financial transactions, is an important step towards protecting financial security. This tool is fully in the browser's local calculations and does not upload any card number information to ensure your privacy and safety.

What's the Luhn algorithm?
The Luhn algorithm is a simple check-and-check formula that validates the validity of various identification numbers, including bank cards, credit cards, etc. The algorithm was invented by IBM scientist Hans Peter Luhn in 1954 and has now become an international standard.
The Luhn algorithm produces a validation position by making a specific mathematical calculation of the number in the card number. If the calculation can be divided by 10, the card number is valid. This algorithm detects most input errors, but does not guarantee that the card number will exist.
FAQ
Q: Will this tool keep my bank card number?
A: No. All the validations are done locally in your browser, and the card numbers are not sent to any server, nor are they saved.
Q: Must the pass number be real?
A: Not necessarily. The Luhn algorithm only verifies whether the card number is in the correct format and whether it is real or not available.
Q: Which banks are supported with card number certification?
A: Support all bank cards that follow the Luhn algorithm, including credit cards and debit cards for mainstream banks, both domestic and foreign.
Q: Is there a requirement for the length of the bank card?
A: Usually the bank card number is 13-19 bits. The length of cards may vary from bank to card type.
