There are three basic elements of any payment gateway. Secure storage of credit card number as per the PCI DSS, AUTH and Settlement (capture).

  1. Have a service to securely store the card number and return a token or a hash as handle for credit card.

  2. You need rule engine or a service to Identify the CARD TYPE (VISA, MC, DISC, AMEX etc.) from BIN .

  3. An ESB or content based router to send the request to appropriate acquirer based on CARD TYPE or BIN.

  4. A service with high SLA to perform a real-time AUTH

  5. A service or batch job for settlement (CAPTURE)
