Security in many areas receives a great deal of attention increasingly from people. The traditional identity authentication technique is easy to be counterfeited, so the paper’s original intention is to assure products of security and reliability. At present, the cash money box products of civil financial industry still use the traditional identity authentication technique, so the security, in the flowing processes of money box, for example, in and out vault, cash truck escorting and in storeroom, etc., is to be threatened seriously.Considering the current products’ function requirement, based on electronic lock’s intelligent features of the old cash money box, using uniqueness and reliability of fingerprint identification techniques, and fingerprint lock’s higher security joint defense and super authorization ability, the fingerprint lock system was designed based on data acquisition system of cash money box. In system, MSP430 microprocessor is designed as the first identity authentication, non-contact RF IC and keyboard password input are designed as the second identity authentication, nonvolatile mass storage is also involved, and final result will be displayed by LCD, besides, the security and reliability of the system are personalized.Friendly interface and powerful functions of the fingerprint lock system meet demand for users. The system is divided into two parts:product hardware and product flow. Embedded system of MCU as core component, data collection, fingerprint identification and encryption techniques enhance the system’s reliability. In the designing stage, the identification and encryption techniques were analyzed and argued systematically, so in the flowing process of money box, for instance,in and out vault, escort, etc.,it will be higher security limits and intelligent ability of tracking and recording.Considering disadvantages of single identity authentication and higher security of multiple authentications, the system includes fingerprint identification, IC and keyboard password techniques, etc. Using C51 to design control system based on MSP430, and SQL and C# to create database and management platform, the product will be more personalized and market share.
