Short answer

How can my AI tell if a card is Visa, Mastercard, Amex, or Discover?

Your AI runs the card number through the Luhn CC Validator to confirm it's a valid number and detect the specific brand. This allows your agent to automatically format the correct payload for your payment processor. You'll see the breakdown of how it handles these checks below.

The results.

Where your data lands.

The AI sorts the results based on the card's validity and brand.

VALID

Brand identified

The AI confirms the number passes the Luhn check and identifies the brand. You get a clean object ready for your transaction logic.

INVALID

Error flagged

The AI catches numbers that fail the checksum. It flags these immediately so you don't send bad data to your gateway.

UNKNOWN

Brand mismatch

If the number passes the checksum but doesn't match known brand patterns, the AI marks it as an unknown brand for you to review.

HUMAN

Manual review needed

When the AI hits a brand it doesn't recognize or a suspicious pattern, it stops and asks you to check the input manually.

The workflow

What your AI does when a card number arrives.

The AI handles the math and the pattern matching so you don't have to.

  1. Check checksum

    The AI runs the number through the Luhn algorithm to ensure it's a mathematically valid credit card number.

  2. Detect brand

    Once validated, the AI looks at the prefix and length to determine if it's Visa, Mastercard, Amex, or Discover.

    validate_luhn

  3. Format payload

    The AI prepares the specific data structure required for the identified brand.

    validate_luhn

  4. Report results

    The AI gives you a clear status update on whether the card is usable or needs attention.

  • Check if this card number is valid and tell me the brand: 4111111111111111

  • Look at the card numbers in my 'payments.csv' file and identify which ones are Amex.

  • Validate this list of numbers and format them into a JSON payload for a Visa transaction: [4242..., 5105...]

  • Scan my recent support tickets for any invalid card numbers that failed the Luhn check.

FAQ

How this task behaves.

  • 01

    Can the AI process actual payments?

    No. The AI only validates the numbers and identifies the brands to help you prepare data. It does not move money or connect to a payment gateway.

  • 02

    Does the AI store my credit card numbers?

    No. The AI processes the numbers through the tool to provide an answer, but it does not save or store the sensitive data.

  • 03

    Can the AI fix a typo in a card number?

    No. If a number fails the Luhn check, the AI will tell you it's invalid. It won't guess what the correct number should be.

  • 04

    Will the AI automatically send this data to my bank?

    No. The AI prepares the data for you. You decide when and where to send that data using your own payment tools.

  • 05

    What happens if the brand isn't Visa or Mastercard?

    The AI will attempt to identify the brand using the available logic. If it can't match it to a known brand, it will flag it as unknown.
