Test-A-Credit-Card - an open-sourced data API implementation to perform pre-transactional credit card queries for fraud prevention and consumer defense
An API driven SaaS application to verify the credit card issuing bank data tokens, validate the credit and debit card numbers, and match transaction initiating GEO location to the purchaser’s billing address just before the actual transaction
Test-A-Credit-Card provides an inclusion of transaction requesting party GEO location data, number validation algorithms such as Luhn formula known as “modulus 10”, extensive credit and debit cards variables validation using the BIN (Bank Identification Number) number database.
Credit Card Number Validation
The card numbers verified and validated using the service are matched against the algorithms tokens and the BIN database information. When the service identifies the card as valid, it implies that the combination of characters which validate the sequence when passed through the MOD 10 algorithm is an exact match. Issuing payment networks utilize their particular prefixes which are verified the time of a payment transaction using the algorithms available.
Note that the basic level test API does not check whether a valid credit card number is active or not or has a balance to fulfill the actual transactions.
Instant Credit Card Verification
In order for a credit card number to be instantly validated and verified, it has to be analyzed via the MOD 10 method and a Bank Identification Number database. These verification tools are specifically designed to prevent errors such as those occurring in typos.
Using the Major Industry Identifier (MII) and the Issuer Identification Number (IIN) (as a prefix for a credit card number) and then the rest of the card number, the sequence us verified against an eight or consequently six digit key from a BIN database .
The verification process, including the actual test charge are performed within seconds and provide virtually instant validation, bank network functionality and the balance feedback for the evaluated card payment method.
Why Instant Card Check is Useful?
The API credit card number check and verification is utilized for the following:
- Server side remote API query to prevent payment forms abuse and merchant gateway request flooding while avoiding fraudulent transactions
- Prevention of payment fraud via using a range of IP addresses currently involved in transaction fraud across all users of the service.
- Product delivery warning system sends alerts to vendors that are indicative of possible fraud and minimize the product loss via buyer fraud.
- Pre-transaction credit card verification to identify whether the customers posses a valid form of payment before the actual product or service charge is executed.
