I am curious about finding the cost to a big bank to process something like a bank transfer from one account to another...
I am thinking about my bank, where I have two accounts, where I may move a few hundred dollars from one account to another.
Is the cost less than a penny for such a transaction for a website or an iPhone app to make such a transfer? I assume there are overhead costs where auditors review blocks of transactions, but I am not asking about that. Just the marginal cost for a hosted and highly secure website to process a transaction.
Does anyone have an idea about this?
