The invention relates to a method for utilizing a
fingerprint as a traffic
ticket. The method comprises the following steps that: a
ticket purchaser fills in a
ticket purchasing sheet; ticket-selling staff collects a
fingerprint of the ticket purchaser, and stores the ticket
purchasing sheet and the
fingerprint of the ticket purchaser in a ticket
database; a ticket
processing system compares the stored information with the prior
data information and judges whether the ticket purchaser is a repetitive ticket purchaser or a person with low credit standing or not; the ticket is sent to a non-repetitive ticket purchaser with high credit standing; the
train number, the seat number, the departure location, the departure time and the arrival location are bond with the fingerprint of the ticket purchaser; when passengers enter a
station, the passengers press the fingerprints, and according to the fingerprints, whether the passenger can enter the
station or not is checked; when the passengers leave the
station, the passengers press the fingerprints, and according to the fingerprints, whether the passenger can leave the station or not is checked; when one passenger traffic work is finished, the ticket
processing system automatically carries out the check of passenger departure and arrival; if no passenger departure information is in the ticket
database, the passenger is considered as ticket evasion; and corresponding credit standing value of the fingerprint of passenger in the ticket
database is reduced.
