Here are the questions we've covered during the interview:

- tell us the rough outline of how the current credit/debit card processing look like?
- how many parties are involved in this process? What does inter-party communication look like and who is in charge of facilitating this communication?
- how are the flows for debit and credit card processing different? Why?
- why is it so expensive to accept credit or debit card payments?
- do the higher time limits for chargebacks affect it or is it mostly related to the complexity of communications mentioned in the second question? Or does it have anything to do with the potential NSF issues?
- key solutions that you see for all the problems we've discussed?
