Cheques are clearly on the way out. Just saying there are some situations where they are still useful. Do all electronic bank transactions show up immediately, I didn’t think so.
Some show up straight away - some don't. It depends on who the 'from' and 'to' banks are. Going back some years, all payments were processed at the end of the day. Then it changed and payments are now batched processed several times intra-day. A payment from me to you if we're both say BNZ customers will happen almost instantly. Between different banks it may take a few hours or be done overnight.
