Self-Service Technologies (SSTs) are technological interfaces allowing customers to produce services independent of involvement of direct service employee. Self-Service technologies are replacing many face-to-face service interactions with the intention to make service transactions more accurate, convenient and faster.
Examples of SSTs
Automatic Teller machines (ATMs), Self pumping at gas stations, Self-ticket purchasing on the Internet and Self-check-out at hotels.
