| 密码识别门禁系统 Password Recognition Access Control System 通过检验输入密码是否正确来识别进入权限。这类产品又分为两类，一类是普通型，一类是乱序键盘型（键盘上的数字不固定，不定期自动变化）。 Entry privileges are identified by verifying that the input password is correct. This kind of products can be divided into two categories, one is the general type, the other is the disorderly keyboard type (the number on the keyboard is not fixed, and the number changes automatically from time to time). 密码识别的优点是操作方便，无需携带卡片，成本较低。缺点是安全性较差容易泄露，只能单向控制，没有开门记录，按键容易损坏、失灵。 The advantages of password recognition are easy operation, no need to carry cards and low cost. The disadvantage is that the security is poor and easy to leak, only one-way control, no open door record, keys are easy to damage and failure. 根据卡片的种类可以分为接触卡门禁系统(磁条卡、条码卡)和非接触卡(又叫感应卡、射频卡)门禁系统。接触类产品的由于接触使用的卡片容易磨损且信息易复制、易被外界磁场干扰致使失效，使用场景较少，一般只在和银行卡(磁条卡)有关的场合被使用。非接触卡具有使用方便、耐用性强、读取速度快、安全性较高等优势。 According to the types of cards, they can be divided into contact card access control system (magnetic bar card, bar code card) and non-contact card access control system (also known as induction card, radio frequency card). Contact cards are easy to wear and tear, information is easy to replicate, and are easily invalidated by external magnetic field interference. There are fewer scenarios used in contact products. They are generally only used in the occasions related to bank cards (magnetic strip cards). The non-contact card has the advantages of convenient use, strong durability, fast reading speed and high security. |
