Why Validate Credit Card Numbers?
Validating Credit Card Numbers has many benefits including helping to reduce the number of transactions that need to be returned by the payment service provider and if payment is to be taken offline at a later time.
This validation saves time and money because it significantly decreases the number of erroneous transactions.
Not only that, but eSortcode.com can also determine the type of card that is being used from the credit card number and therefore reduces potential input errors.
Why use eSortcode?
The ValidateCreditCard method of the eSortcode.com web service encapsulates the validation and return of the card type in a single operation.
This service uses Modulus checking and validates the card against a list of Bank Identification Numbers (BINs) ensuring that card details are captured accurately and with minimum of effort on behalf of the end user.
