With the enhancement of people’s brand awareness, various anti-counterfeiting technologies emerge in an endless stream. How to pursue anti-counterfeiting performance while having simple and easy to query functions, NFC anti-counterfeiting technology came into being. RZX NFC anti-counterfeiting label is an electronic anti-counterfeiting label, mainly used To identify the authenticity of the product, protect the company's own brand products, prevent counterfeit and anti-counterfeit products from circulating in the market, and protect the consumer rights of consumers.

For example, the NFC Moutai anti-counterfeiting label is an electronic anti-counterfeiting label. The electronic anti-counterfeiting label is attached to the product packaging. Consumers use the NFC mobile phone to identify the electronic anti-counterfeiting label, verify the authenticity information, and read the product-related information. Such as: manufacturer information, production date, origin, specifications, etc., decrypt the label data and determine the authenticity of the product.

One. NFC anti-counterfeiting label-MINI is powerful

The NFC anti-counterfeiting chip uses near-field communication technology to enter product information into a small chip, and integrates the anti-counterfeiting label with the product through technical means such as embedding, attaching, and synthesizing. When it is close to the reading/entry device, Update commodity circulation/verification information, and the high cost of imitation of the chip and the difficulty of copying the real information of the commodity, becoming an NFC chip can become an advantageous feature of an anti-counterfeiting label.

Near field communication (NEAR FIELD COMMUNICATION) is an emerging technology. Devices using NFC technology (such as mobile phones) can exchange data when they are close to each other. It is connected by non-contact radio frequency identification (RFID) and interconnection. The integration and evolution of intercommunication technology, through the integration of inductive card readers, inductive cards and point-to-point communication functions on a single chip, the use of mobile terminals to achieve mobile payment, electronic ticketing, access control, mobile identification, anti-counterfeiting and other applications. Although the communication distance is only about 10CM, like the non-contact IC card technology, data can be exchanged between different electronic products by "just a touch."

Two. Anti-counterfeiting verification, fake goods have nowhere to hide

The basic idea of ​​product anti-counterfeiting is to give this product a logo and only associate it with a specific platform. If the logo is not found on the associated platform, then the item is deemed to be a counterfeit product.

Three. Electronic anti-counterfeiting, the possibility of counterfeiting is "0"

RFID and NFC have strong anti-counterfeiting capabilities. Each chip has a UID with a global wei one. Counterfeiters cannot obtain the corresponding UID chip. The technical threshold is very high. The information of each link of the product can also be written and stored, and the product can be traced. , So it cannot be faked. Especially NFC technology eliminates the possibility of fraud. Even if the counterfeiter spends a lot of money to obtain equipment, it is impossible to counterfeit the chip with the technology of making and rewriting the chip.

Fourth, how does NFC prevent it from being counterfeited?

1. Fragile label

In response to the actions of counterfeiters recycling labels, filling real bottles with fake wine, etc., NFC anti-counterfeiting fragile labels are made, and the label structure design is added. Once the wine is opened, the label will be broken and cannot be used again. The label, the label must be broken, even if it is taken off, it cannot be used.

2. Anti-cloning

In response to the behavior of counterfeiters cloning tags, RZX Technology performs the built-in encryption algorithm on the NFC chip in the tag, and the asymmetric encryption algorithm obtains the ciphertext. Such ciphertext is irreversible. Even if the counterfeiter obtains the chip ID, Can not get the ciphertext. The high cost of NFC chips will discourage many counterfeiters. Coupled with encryption algorithms and irreversible ciphertexts, the idea of ​​cloning and imitation by counterfeiters can be shut out.

3. Safety

The 7-byte wei-UID is locked when leaving the factory, and the ID number is guaranteed to be wei-1; it is locked after the data is written, and no one (including the developer) can change it and can only read it; 32 bits Secret key protection, unauthorized, unable to write, wooden monster brute force attack invalid times setting function.

4. Other skills

No APP is required. Consumers use NFC for anti-counterfeiting verification without downloading an APP, which is one of the differences from RFID anti-counterfeiting. No APP is required to make NFC anti-counterfeiting have a better user experience, strong combination, NFC + blockchain, a good partner for anti-counterfeiting and traceability!

Five, the difference between NFC and RFID

1. NFC is an integrated chip

NFC integrates contactless card readers, contactless cards and point-to-point functions into a single chip, while rfid must be composed of readers and tags. RFID can only read and determine information, while NFC technology emphasizes information interaction. In layman's terms, NFC is an evolved version of RFID, and both parties can exchange information at close range. The NFC mobile phone has a built-in NFC chip, which forms part of the RFID module. It can be used as an RFID passive tag for payment; it can also be used as an RFID reader for data exchange and collection, and it can also communicate data between NFC mobile phones. .

2. NFC transmission range is smaller than RFID

The transmission range of RFID can reach several meters or tens of meters, but due to the unique signal attenuation technology adopted by NFC, compared with RFID, NFC has the characteristics of short distance, high bandwidth, and low energy consumption. In terms of applications, NFC is more for consumer electronic devices to communicate with each other, and active RFID is better at long-distance identification. With the popularization of the Internet, the mobile phone, as a direct intelligent terminal of the Internet, will surely cause a technical upgrade. Just like the previous standard configuration of Bluetooth, USB, GPS, etc., NFC will become an important standard for mobile phones in the future. Through NFC technology, Mobile payment, watching movies, and taking the subway can all be realized and will play a greater role in our daily lives.

Six, the advantages and characteristics of electronic anti-counterfeiting

1. Wei is oneness

A truly safe anti-counterfeiting method, using a high-strength cryptographic algorithm, each piece of electronic label data corresponds to the product wei, and cannot be copied or forged;

2. Low operating threshold

There is no need to establish a product database and directly read the encrypted data of the electronic tag to achieve anti-counterfeiting, which can greatly reduce the operating cost of the NFC anti-counterfeiting system;

3. Multiple anti-counterfeiting

Combination of printed anti-counterfeiting and electronic label anti-counterfeiting;

4. Convenient identification

Consumers only need to use the NFC mobile phone, close to the chip, can easily identify the authenticity of the product information, simple and convenient;

5. Anti-transfer

RZX technology can adopt anti-transfer, anti-counterfeiting and fragile labels, attached to the unpacking part of the package, and the label will become invalid when opened.

Seven. NFC anti-counterfeiting labels, application cases in the cosmetics industry

1. Attach UHF jewelry tags or NFC anti-counterfeiting and fragile tags to single products, and stick them to the opening of the product or package. Due to the variety of cosmetics, single product packaging is also diverse. It is recommended to use shrinkage if the label cannot be used. The product, put the label on the shrink;

2. Each NFC anti-counterfeiting and fragile tag has an ID number of wei one in the world, and cannot be counterfeited or tampered with. The NFC anti-counterfeiting fragile label can achieve the effect of tearing and destroying, and it cannot be transferred twice. It can realize the information management of product production statistics, circulation traceability, sales data, etc.;

3. Adopting the UHF electronic label on the large packaging box of the whole box, which can realize the management of product entry and exit, and the problem of warehouse inventory;

4. The shipper and the warehouse use handheld computers to query and track the goods;

5. Inquiries by couriers and consumer terminals can be read using NFC mobile phones.

Eight. Rich usage scenarios, suitable for a variety of industry needs
