Yes, sir. If we assume that my 30¢ model works for the cost of the transaction proper, the switch fee, which is the Interac fee, I understand is in the order of 2¢ to 15¢, which would make it, say, 35¢ or 40¢ in total. There would then be some technology costs associated with the back-and-forth exchange of information between the two banks.
But to my mind, the 60¢ own-bank fee, which I use as a benchmark, would certainly compensate the banks for their total costs and I think would be fair to consumers.
