Question
Validating an ABN Bank Routing Number
We have created a web based application in asp.net using vb.net. In this we have a form that takes some bank details from the visitor that also includes ABA/Routing Number. What we want to do is validate the ABA/Routing Number in real-time using some database.
We are actually looking forward to some secure method like validating the credit card number in real-time using authorize.net or something.
Thanks!
