Relay services act as intermediaries that facilitate the transfer of data, goods, or financial transactions between two or more points. In telecommunications, for instance, relay services are critical for transmitting signals from cell towers to mobile devices, ensuring seamless connectivity. Similarly, in logistics, relay services encompass the transfer of goods at various points in a supply chain, optimizing delivery times and efficiency. In finance, relay services often involve payment processors that interlink buyers and sellers, especially in cross-border transactions.
