NFC anti-counterfeiting chip uses near-field communication technology to input commodity information into a small chip, and integrates anti-counterfeiting labels with commodities through technical means such as implantation, pasting, and synthesis. When it is close to the reading/entry device , Update the circulation/verification information of the product, but the cost of imitation of the chip is high and the real information of the product is difficult to copy, which becomes the most advantageous feature that the NFC chip can become an anti-counterfeiting label.

The basic idea of product anti-counterfeiting is to give this product a unique logo, and it is only associated with a specific platform. If this unique identification cannot be found on the associated platform, then the item is identified as counterfeit.


· A unique identity


·Only associated with specific platforms


·Identification and platform information comparison


Mismatched results: identified as counterfeit


RFID and NFC have strong anti-counterfeiting capabilities. Each chip has a unique UID in the world. Counterfeiters cannot obtain the chip corresponding to the UID. The technical threshold is very high. It is also possible to write and store the information of each link of the product to trace the source of the product. Therefore it cannot be faked. Especially the NFC technology completely eliminates the possibility of counterfeiting. Even if counterfeiters spend a lot of money to get equipment, they can't fake it with chip production and rewriting technology.


How does NFC not be counterfeited?


1. Fragile labels

Aiming at counterfeiters' behaviors of recycling labels and filling fake wines with real bottles, fragile labels are made, coupled with the design of the label structure, as long as the wine is opened, the label will be broken and cannot be used again! If the label is removed , the label must be broken, even if it is taken off, it cannot be used.


2. Anti-cloning

Aiming at the act of cloning tags by counterfeiters, the NFC chip in the tag is built with a high-security encryption algorithm, and an asymmetric encryption algorithm is used to obtain ciphertext. Such ciphertext is irreversible. Even if the counterfeiter obtains the chip ID, There is also no way to get the ciphertext. The high cost of NFC chips will discourage many counterfeiters, coupled with high-security encryption algorithms and irreversible ciphertext, completely shut out the idea of counterfeiters cloning and imitating.


3. Security

The 7-byte unique UID is burned out from the factory to ensure that the ID number is unique; after the data is written, it is burnt down, and no one (including the developer himself) can change it and can only read it; 32-bit secret key protection , Unauthorized, unable to perform write operations, wood demon violent attack invalidation times setting function.


4. Other skills

No APP required. Consumers use NFC for anti-counterfeiting verification without downloading APP, which is one of the differences from RFID anti-counterfeiting. No need for APP to make NFC anti-counterfeiting have a better user experience, grab the joint, NFC + blockchain, the strongest partner in anti-counterfeiting traceability!
