Fingerprints locker uses technology of fingerprint identification,it improves the security, makes the system convenience to use,and reduces the cost of maintenance.Hardware and software design of fingerprints locker is introduced in this paper.Through comparison, it can be found that this two lockers has its pluses and minuses.Barcode automatic locker is simple in design,but its security is poor than fingerprints locker,so it appears more in general places.Fingerprints locker is complex in its design,but it has high security,so it appears more in places where need high security.Key Words: automatic locker; SCM AT89C52; barcode; fingerprint identification引言在大型超市、图书馆、游泳馆、火车及汽车站，人们经常需要寄存包裹。采用人工方法存取包裹即费时又费力，与信息社会格格不入。故而本论文设计一套基于单片机AT89C52的自动寄物柜的微机系统，能够完全实现自动化。用户只须按存包键，某一柜门自动打开，同时系统打印条形码、密码和柜号。当用户取包时，只需将条形码贴在扫描器上，待扫描器确认条形码正确后其柜门再次打开，用户取包离开。虽然传统的寄物柜系统得到了广泛的应用，但有安全性差、使用不便和维护成本高等缺点。将指纹识别技术应用到寄物柜系统中，提高了系统的
