The invention relates to an offline electronic ticketing
system and a method thereof, in particular to an electronic ticketing
system capable of checking tickets off line and a method for
purchasing, checking and returning tickets. The
system comprises an electronic ticketing platform, a
ticket booking terminal and a
ticket checking terminal, wherein the owner of the
ticket booking terminal is a
client, and the owner of the ticket checking terminal is a merchant; the electronic ticketing platform is connected with the ticket booking terminal and the ticket checking terminal by
Ethernet or a
mobile communication network; and the basic process comprises the following steps that: a
digital signature is performed by the electronic ticketing platform on an electronic ticket which is provided by the merchant; then, the electronic ticket and the
digital signature of the electronic ticket are manufactured into a two-dimensional
barcode; the electronic ticket and the two-dimensional
barcode are sent to the
client who books the ticket; and under the condition that the merchant is off line, the
digital signature of the electronic ticket and the ticketing information on the electronic ticket which are contained in the two-dimensional
barcode provided by the
client are checked by the ticket checking terminal so as to determine whether the electronic ticket is real, valid and complete. Due to the adoption of the system and the method, the operation cost of the electronic ticketing system is reduced, the ticket
purchasing time of clients is saved, and the ticket checking speed is improved.
