CardVal is a DLL that allows developers to easily include credit card validation/identification in their applications. CardVal is easy to use, requiring only one line of code to validate a credit card. CardVal also has a low filesize (just 32kb), minimizing the impact upon your software's installation size. CardVal can validate the following types of credit cards: - VISA - Mastercard - Eurocard - American Express - Diners Club - Carte Blanche - Discover - enRoute - JCBCardVal can be used with any programming language that supports COM. E.g.: VBScript, JavaScript, Visual Basic (Versions 4 and above), VBA (Word, Excel, Access etc.), Visual C++, Borland C++, Delphi, Power Builder, Java, ASP and more. Here is an example piece of Visual Basic code that will do a simple validation check on a VISA card: Dim CardVal As CardValTrial.Validator Set CardVal = New CardValTrial.Validator Result = CardVal.CheckCC('4111-1111-1111-1111', 'V') If Result <> 0 Then MsgBox 'Credit Card Not Valid!' CardVal can also perform much more complex validation, and is capable of returning the following results (including combinations of them): - Card is Valid - Card Number Does Not Match Specified Card Type - Card Number Length is Invalid - Card Checksum Failed (Main Validation) - Unknown Card TypeThe trial version is limited to 10 validations per DLL session.
