Quatech Products Used: DSU-100 2 Port USB to RS-232 Serial Adapter

In addition to farecard kiosks, public transportation systems also include turnstiles that can read the farecards generated by the kiosks. These turnstiles also typically contain an embedded computer, as show in the above drawing, that provides USB expansion ports. They also contain a card reader/writer that can read and update paper farecards as well as Smartcards (fare cards that are typically work across a wide range of transportation systems and that are "filled" with funds by the consumer via phone or e-mail and linked to a bank account or credit card account). The embedded computer is linked via Ethernet to a back office server that validates the cards and records starting point on entry and deducts the appropriate fare on exit. Once the card is validated and charged, the turnstile receives a signal to open the gate, which is accomplished with a gate-release mechanism that is connected to the embedded PC via the DSU-100's second serial port.
