Are confirmation numbers really confirmations, or are they just record keys? That is to say, how does a confirmation prove that I paid my gas bill other than to uniquely identify my payment record? If their database farts and my payment record gets lost, is my confirmation number worthless? My guess is yes. What they really need to do is cryptographically sign a receipt at the time of payment that I can hang onto. It won't prove that I paid, but it can prove that they said I did, which is good enough for me. I suspect most people haven't thought about what a confirmation number really means, otherwise they'd realize that it probably doesn't confirm much of anything.
