门禁管理是现代安全防范系统的重要组成部分，随着国内对门禁系统的安全性、先进性和稳定性要求的提高，迫切需要一种高性能的门禁系统，现在比较常用门禁系统主要有生物识别(指纹、掌形、虹膜等)和以射频卡系统为代表的系统，虽然传统的以射频卡为代表的门禁系统能取到一些作用，但从本质上来说，是检验人持有的"物"，而不是验证其本人，只要"物"的有效性得到确认，则持有该"物"的人就被认为是合法者。盖土网 防寒布 麻绳 油麻绳 麻刀 沥青麻绳 静压造型线 自动浇注机 铸铁拍门 钢制拍门 玻璃钢拍门
Access control is an important part of modern security system. With the improvement of security, advanced and stability requirements of access control system in China, a high-performance access control system is urgently needed. Now, the most commonly used access control systems are biometrics (fingerprint, palm shape, iris, etc.) and the system represented by RF card system. Although the traditional access control system represented by RF card can play some roles, in essence, it is to test the "thing" held by people, not to verify themselves. As long as the effectiveness of the "thing" is confirmed, the person holding the "thing" is considered to be legal.
