Completely eliminate chip cloning and violent cracking!

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.
