Automated Check-In

PSA was also an innovator in self-service ticketing and check-in. PSA realized by the mid-1970s that the majority of their ticket counter transactions were very simple, and with the move to a full computerized reservation system (CPARS), there was the risk in losing the speed advantage that PSA held. To help mitigate this, PSA worked with NCR to create the first self-service ticketing machines, which eventually got sold to other airlines.

With the advent of discount fares, the original machines became obsolete, and were replaced in 1984 with a new generation of machine that could handle the increased complexity of the PSA system by that point.
