Definitions

  • the invention is based on a ticket and a method for creating and checking of such a device for creating a ticket and a control device and a method for claiming a service and a validator Genre of independent claims.
  • US 5754654 describes a sales system for electronic tickets and a method for Selling an electronic ticket described using a terminal with the device is connected, a ticket request being sent from the terminal to the device. If the requested ticket is available, the device sends one to the terminal Request sent for an amount to be paid. Then the corresponding one The amount paid electronically, then the purchased ticket is sent electronically to the terminal transmitted and stored in a storage medium, for example an IC card. After graduation of the sale, the device stores the data of the ticket sold, the one sent Money and the identification of the sender. To increase the security of the transmitted data a signature or encryption can be used.
  • the ticket according to the invention and the method according to the invention for creating and the Method according to the invention for checking such, the device according to the invention to create a ticket and the control device according to the invention have the advantage that they are very easy to use and require little tools become. It is also advantageous that the tickets created are very difficult to forge and are easy to validate. The cost of creating such a ticket can also be to be kept at a low level. Can also be considered advantageous that users only have to accept small changes in the previous procedure.

It is particularly advantageous that the ticket through Security features such as holograms and watermarks are protected against counterfeiting. It is also advantageous that the ticket through an additional machine-readable implementation the code can be read faster and without entering data. The execution of the ticket in paper or plastic material allows inexpensive production of the ticket.

Another advantage is that the payment the service purchased with the ticket is cashless or cash can. Very different types of tickets can be generated in this way.
  • the invention The validator has the advantage that the ticket created can be canceled very easily without that the user needs to completely "relearn" the process. Just as beneficial is that the validity of the ticket can be checked immediately with the validator and the provision of the service can only take place after a successful review.
  • the ticket data is recognized using camera recordings and image recognition methods or by entering the ticket data using a keyboard. Even the invention Control device for a ticket is easy to use and can quickly Check ticket details.

Furthermore, it is assumed as a prerequisite that the labeling by the Validator corresponds to the service actually used. The controller can do this see immediately by looking at the stamp of the validator. For example, compares the controller makes the validation date with the date of the respective day and determined that the dates match. Corresponds to the service actually used not marking the validator, then the user will turn immediately because of unlawful use of a service (e.g. a trip with a public Transportation) is held accountable.
