Just as news is increasingly delivered digitally, so are banking services. Unified Communications and Omni-Channel strategies mean banks communicate with their customers using browser-based video/audio for instance. This could be with a human agent, but in the future also Artificial Intelligence (AI) based agents.
It is not too hard to imagine, therefore, a video/audio conversation between a high net-worth client and their private banker. If the client looks and sounds like him/herself, and of course can provide the answers to any security questions (as they invariably would), why would the banker not acquiesce to any instructions the client gives?
