一个工具类APP，可以读取Veltema公司特制的NFC电子防伪标签用于防伪和溯源。一个特制的标签包括NFC芯片ID、隐藏码和二维码三类信息，三者一一对应。 通过手机读取NFC芯片ID，然后数据库查询可以获取对应的隐藏码和二维码。手机靠近特制的NFC电子标签会点亮LED灯使得自然光下的隐藏码显现出来，和app内查询得到的隐藏码对比用于防伪验证。NFC电子标签上同时还印刷了二维码，既可以作为溯源ID，也可以用于和app内查询得到的二维码对比用于多重防伪验证。 A utility app that can read specially designed NFC anti-counterfeit tags from Veltema for authenticity verification and traceability. Each custom tag contains three types of information: an NFC chip ID, a hidden code, and a QR code, all of which are uniquely linked.The app reads the NFC chip ID via a smartphone, then retrieves the corresponding hidden code and QR code from a database. When the phone is brought close to the special NFC tag, it activates an LED light to reveal the hidden code under natural light, allowing users to compare it with the code displayed in the app for authenticity verification. The NFC tag also features a printed QR code, which serves both as a traceability ID and an additional layer of anti-counterfeit verification when matched against the QR code retrieved by the app.
