Early versions were manual telegraph systems. Later systems using teleprinters were semi-automatic, using punched paper tape to receive, store, and retransmit messages. Plan 55-A, Western Union's last paper tape based switching system (1948 - 1976), was fully automatic, with automatic routing. At Western Union, we understand you are sending more than just money. Outside of digital currencies specifically, the latest earnings announcement from Western Union highlighted the regulatory difficulties that all US companies tied to money transmission are encountering.
