A Standing Order is based on 20+ year old processes. All other things being equal, the money should be in your account tomorrow morning. BoI would have 'handed over the payment' to AIB this (Monday) morning.
An interbank standing order can not 'be done faster'. It could be done faster, but can not be done faster under the existing system.
Why not get your wages paid into the BoI account, if that is where the money needs to be ?
'but the banks have not bothered to change their (Internet) software. '. The banks don't have '(Internet) software'. The processes supporting payments initiated via a browser-based application are similar, but different, to those intiated by Standing Order. The Standing Order payment process has not changed materially in many years. The browser-based applications have.
