Method and device for radio communication between mutually movable objects
First Claim
1. A method for radio communication between mutually mobile objects, the method comprising:
- prior to radio communication between the objects performing calculations with a communication and calculation unit of a first of the objects to produce established data, generating answer codes from the established data, and selecting one of the answer codes for communication to a second of the objects;
carrying out the communication between the objects including transmission of the selected answer code from the first object to the second object and transmission of data from the second object to the first object;
after radio communication between the objects performing calculations with the communication and calculation unit of the first of the objects;
storing a final result of the communication of between the objects and calculations performed by the communication and calculation unit of the first of the objects after radio communication between the objects; and
preventing outside communication with the communication and calculation unit of the first of the objects after communication between the objects, during the performance of calculations by the communication and calculation unit of the first of the objects and storage of the final result.

Abstract
A method for radio communication between mutually mobile objects. Prior to radio communication between the objects, calculations are preformed with a communication and calculation unit of a first of the objects to produce established data, answer codes are generated from the established data, and one of the answer codes is selected for communication to a second of the objects. The communication between the objects is carried out, including transmission of the selected answer code from the first object to the second object and transmission of data from the second object to the first object. After radio communication between the objects, calculations are performed with the communication and calculation unit of the first of the objects. A final result of the communication of between the objects and calculations performed by the communication and calculation unit of the first of the objects is stored after radio communication between the objects. Outside communication with the communication and calculation unit is prevented after communication between the objects, during the performance of calculations by the communication and calculation unit of the first of the objects and storage of the final result.

13. A device for carrying out radio communication between mutually mobile objects, comprising:
-
a communication and calculation unit on each object, the communication and calculation unit comprising wireless communication equipment for communicating between the objects and computer equipment for performing a multi-step calculation and data storage operation; and a data storage medium on a first of the objects, the storage medium comprising changeable contents comprising a balance and answer codes, the answer codes representing the balance; and wherein the calculation and data storage operation comprises selection of an answer code by the first object communication and calculation unit, transmitting the selected answer code from the first object to a second object, storage of the selected answer code by the second object, and storage by the first object of an amount to be deducted from the balance, the first unit further comprises a lock for preventing communication with the communication and calculation unit of the second object after communication between the objects. - View Dependent Claims (14, 15, 16)
