NFC动态ID智能防伪芯片，即是在读取时，芯片的ID号都在随时变化，加密密钥由用户自己掌握，更有两把密钥双重加密，无需担心向第三方透露商业信息。彻底杜绝芯片克隆和暴力破解!NFC dynamic ID smart anti-counterfeiting chip, that is, when reading, the ID number of the chip changes at any time, the encryption key is controlled by the user himself, and there are two keys for double encryption without worrying about disclosing business information to a third party. Completely eliminate chip cloning and violent cracking!

在连网状态下，使用NFC手机靠近标签读取，链接由固定URL+一段加密数据（动态ID）组成，服务器将这段加密数据解码，之后反馈结果页面给手机，手机默认弹出浏览器，显示正品页面和产品信息。鉴真后，链接立刻失效，杜绝芯片数据被克隆，再次鉴真，需要再次使用NFC手机读取标签。In the networking state, NFC mobile phone is used to read near the tag. The link consists of a fixed URL+ a piece of encrypted data (dynamic ID). The server decodes the encrypted data and then feeds back the result page to the mobile phone. The mobile phone pops up a browser by default, displaying the genuine page and product information. After the Jian Zhen, the link immediately lapsed, preventing the chip data from being cloned. Once again, Jian Zhen needs to use NFC mobile phone to read the tag again.
