What is the difference between EMT and EFT?

Could you please elaborate on the distinction between EMT and EFT? I'm curious to understand the key differences in terms of their functionality, application, and the benefits they offer. Are they both related to financial transactions or do they serve different purposes entirely? Additionally, how do they compare in terms of security, speed, and accessibility? It would be great if you could provide a concise yet comprehensive explanation to help me grasp the concept better.
