Figure C 4

How it works:

• The e-ticket sends the information to Control Module via the RF Transceiver.

• The information is then placed in the FIFO for Verification.

• After the verification the CPU displays the valid and invalid e-tickets in the GUI by

green and red spot respectively.

• If the conductor finds any red spot or spots he/she then take a survey of the train and

track the invalid e-ticket holder with his/her hand held device.

• The arrow from the CPU to the RF LOGIC block represent the flow of information

from the server to the e-ticket; such as weather forecast, address of the hotels and

restaurants at the destination station, taxi etc.

NOTE: Logic for long distance e-tickets is similar to that of pre-paid traveling card.

Consequently, we did not draw any block diagram for long distance e-tickets.
