Unattended device based on block chain technology, and payment system and method thereof

Abstract

The invention rates to an automatic payment system and automatic payment method realized based on a block chain technology. The system comprises a vehicular terminal, a roadside unit, a background server, a block chain network and an unattended device. According to the method, the vehicular terminal interacts with the roadside unit of the unattended device in advance through a communication module, thereby sending vehicle information, a service request and payment account information; the roadside unit forwards the information to the background server; the background server mounts the information or a calculated digest of the information in a block chain network, generates an automatic identification code and returns the automatic identification code to the vehicular terminal through the roadside unit; and when a vehicle is driven nearby the unattended device, the unattended device verifies the automatic identification code sent by the vehicular terminal and provides set service under the condition that verification is successful. On the basis of the method, the system and the unattended device provided by the invention, the set service is automatically provided, the automatic payment can be finished, the operation is simple, and the use experience is good.

Description

technical field [0001] The present invention relates to the application field of block chain, in particular to a payment method and payment system based on block chain technology, and more particularly to an unattended device based on block chain technology, and its payment system and method. Background technique [0002] In recent years, with the continuous increase of labor costs and the continuous thinning of oil sales profits, self-service refueling will gradually become a sales model vigorously promoted by major oil sales companies. However, in the process of self-service refueling, preventing malicious damage to refueling equipment and car owners evading fees is a matter of great concern to major gas stations. At present, in order to prevent car owners from escaping fees, the usual method is: 1) the user first applies for a special recharge card, and inserts the recharge card into the card slot when using it, but this recharge card is not universal and cannot be used...
