Offline collection terminal and system based on network port and collection and withdrawal method

Abstract

The invention discloses an offline collection terminal and system based on a network port and a collection and withdrawal method. The collection terminal comprises a safety main control chip, a network communication module, a storage module and a power supply module, wherein the network communication module is used for establishing data communication between the safety main control chip and external equipment; the safety main control chip stores a user private key, supports high-speed security encryption calculation, and is used for processing collection and withdrawal services and carrying out signature and signature verification processing based on the user private key in a collection and withdrawal process; the storage module is connected with the safety main control chip through a high-speed data interface and is used for storing collection transaction data; and the power supply module is used for providing a working power supply for each module in the whole machine. The collection process and the withdrawal process are both processed in the collection terminal, and the front-end POS machine is only used as an unvarnished transmission channel, so that the functional requirements of the front-end POS machine are simplified, and the hardware cost and the maintenance cost of collection equipment are reduced.

Description

technical field [0001] The invention relates to the technical field of financial payment, in particular to an offline payment collection terminal, system, and payment collection and cash withdrawal method based on a network port. Background technique [0002] In recent years, with the vigorous development of mobile payment, its influence has covered all aspects of people's lives. Mobile payment can be classified into online transactions and offline transactions according to its network characteristics. However, due to unfavorable factors such as network coverage and transmission delay, offline payment is more suitable for some high-concurrency and centralized payment scenarios, such as subway stations, ETC, food courts, etc. In these scenarios, the traditional method is to use a batch of payment collection devices, each device collects money independently, and independently synchronizes with the background online, resulting in high equipment hardware costs and maintenance c...
