Method and apparatus for offline payment, service processing, and payment processing

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• establishing a communication connection between a service device and an end-user device, wherein both the service device and the end-user device are in an offline state;
• receiving, by the end-user device through the communication connection established to the service device, service data sent by the service device;
• generating, by the end-user device, a first service record based on the service data and account information of the end-user device;
• sending, by the end-user device and through the communication connection, the first service record to the service device;
• generating, by the service device, a second service record based on the first service record and the account information of the end-user device;
• sending, by the end-user device, the first service record to a server when the end-user device is in an online state;
• sending, by the service device, the second service record to the server when the service device is in an online state;
• performing, by the server, service processing based on the first service record and the second service record;
• and
• determining, by the server, based at least on a first amount, the account information of the end-user device, account information of the service device comprised in the first service record, a second amount, the account information of the end-user device, the account information of the service device comprised in the second service record, whether the first service record matches the second service record.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform operations comprising:
• establishing a communication connection between a service device and an end-user device, wherein both the service device and the end-user device are in an offline state;
• receiving, by the end-user device through the communication connection established to the service device, service data sent by the service device;
• generating, by the end-user device, a first service record based on the service data and account information of the end-user device;
• sending, by the end-user device and through the communication connection, the first service record to the service device;
• generating, by the service device, a second service record based on the first service record and the account information of the end-user device;
• sending, by the end-user device, the first service record to a server when the end-user device is in an online state;
• sending, by the service device, the second service record to the server when the service device is in an online state;
• performing, by the server, service processing based on the first service record and the second service record;
• and
• determining, by the server, based at least on a first amount, the account information of the end-user device, account information of the service device comprised in the first service record, a second amount, the account information of the end-user device, the account information of the service device comprised in the second service record, whether the first service record matches the second service record.
