We want to develop an application through which a User can Register the ATM Card. The Application should be able to track transactions of the ATM Card. Any transaction should be trigering an event in the Application. We wanted to use CardSpring but I am having trouble contacting them for support. Please advice. Alternatively please suggest some other Gateway for this whose API we can use.
