| D卡开门的权限就在于卡片背后的这一串序列号，而有些小区为了降低成本，大量的采用了这种价格低廉的门禁卡。让人担心的是，这种拷贝机在网上就能很轻易的买到，价格不到两百块钱。这种门禁只是安防最初级的设备，技术含量很低。 The right of D card to open the door lies in the serial number behind the card. In order to reduce the cost, some residential districts have adopted a lot of low-cost access cards. What worries us is that this kind of copier can be easily bought online at a price of less than 200 yuan. This kind of entrance guard is only the first level equipment of security, and its technical content is very low. 怎么防止自己的门禁卡被复制呢？ How to prevent your access card from being copied? 管理因素：小区可以定期对门禁卡序列号进行刷新或者更换有加密措施的IC卡，把编码换了，以前的也就自动作废了。 Management factors: the community can regularly refresh the serial number of the access card or replace the IC card with encryption measures, change the code, the previous will automatically be scrapped. “无论什么样的门禁卡，在行家面前都能被破解。” 一业主苦闷。所谓“一物降一物” ，“水能载舟，亦能覆舟”，世界上没有绝对安全的事物，一切都是相对而言的，因此安全防范不能寄希望于一个门禁卡，在门禁的基础上，配合安保人员和居民的自身防范，才能做 到万无一失。 "No matter what kind of access card, it can be cracked in front of experts." One owner is depressed. There is no absolute security in the world. Everything is relatively safe. Therefore, security precautions can not rely on an access card.
