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.
