NFC anti-counterfeiting technology

- Oct 14, 2019-

Where there are people, there are rivers and lakes! Where there are interests, there will be people who want to do it, even if they know that this hurts others! Even his purpose is to profit from harming others! After a product is born, There are always people who want to copy, counterfeit, or even just borrow names. This practice has greatly damaged the interests of consumers and genuine merchants, and also disrupted the market. As a result, NFC anti-counterfeiting technology came into being!

The NFC anti-counterfeiting label is an electronic anti-counterfeiting label. It is mainly used to identify the authenticity of products, protect the company's own branded goods, prevent counterfeit and anti-counterfeiting goods from circulating in the market, and protect consumers' consumer rights.

For example, the NFC Moutai security tag is an electronic anti-counterfeit tag. The electronic anti-counterfeit tag is attached to the product packaging. The consumer identifies the electronic anti-counterfeit tag through the APP on the NFC mobile phone, verifies the authenticity information, and reads the product-related information. Such as: manufacturer information, production date, place of origin, specifications, etc., decrypt the tag data and determine the authenticity of the product.

First, NFC security label - MINI body is powerful

The NFC anti-counterfeit chip uses the near-field communication technology to record the product information into a small chip, and integrates the anti-counterfeit label and the product through the techniques of implantation, labeling, and synthesis, and is close to the reading/recording device. , update the circulation / verification information of the product, and the imitation of the chip is high and the real information of the product is difficult to copy, which becomes the most advantageous feature of the NFC chip to become an anti-counterfeit label.

NEAR FIELD COMMUNICATION is an emerging technology that uses NFC-enabled devices (such as cell phones) to exchange data in close proximity to each other, through contactless radio frequency identification (RFID) and interconnection. The integration of interoperability technology has evolved. By integrating inductive card readers, inductive cards and peer-to-peer communication on a single chip, mobile terminals are used to implement applications such as mobile payment, electronic ticketing, access control, mobile identification, and anti-counterfeiting. Although the communication distance is only about 10CM, like the non-contact IC card technology, "just touch" can exchange data between different electronic products.

Second, anti-counterfeiting verification, fake goods nowhere

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

· A unique logo

· Only associated with a specific platform

· Identification and platform information comparison

·Results do not match: identified as counterfeit products

Third, electronic anti-counterfeiting, the possibility of fraud is "0"

RFID and NFC have strong anti-counterfeiting capabilities. Each chip has a globally unique UID. The counterfeiters cannot obtain the chip corresponding to the UID. The technical threshold is very high. The information of each link of the product can be written and stored, and the product can be traced. Therefore, it is impossible to make a fake. In particular, NFC technology completely eliminates the possibility of fraud. Even if the counterfeiters spend a lot of money on the equipment, they can't make fakes with the chip making and rewriting technology.

4. How does NFC do not be counterfeited?

1, fragile label

For the counterfeit to recycle the label, the real bottle of fake wine, etc., made a fragile label, coupled with the label structure design, as long as the wine is opened, the label will be broken, can not be reused! The label must be broken, even if it is taken down, it cannot be used.

2, anti-cloning

For the behavior of the counterfeiter to clone the label, the NFC chip in the label is built with a high security encryption algorithm in the chip, and the asymmetric encryption algorithm obtains the ciphertext. Such a ciphertext is irreversible, even if the counterfeiter obtains the chip ID, Nor can I get cipher text. The high cost of NFC chips will discourage many counterfeiters, coupled with high security encryption algorithms and irreversible ciphertexts, completely rejecting the idea of counterfeiting clones.

3, security

The 7-byte unique UID is burned from the factory and the ID number is unique. After the data is written, it burns to death. Anyone (including the developer itself) can't change it. It can only be read; 32-bit key protection Unauthorized, unable to write, the function of setting the number of invalidation attacks.

4, other skills

No APP required. Consumers use NFC for anti-counterfeiting verification without downloading the 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, robbing the joint, NFC + blockchain, anti-counterfeiting trace the strongest partner!

Five, the difference between NFC and RFID

1, NFC is an integrated chip

NFC integrates contactless readers, contactless cards and peer-to-peer functionality into a single chip, and rfid must consist of readers and tags. RFID can only read and judge information, while NFC technology emphasizes information interaction. Popularly speaking, 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 is part of the RFID module and 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 also for data communication between NFC phones. .

2, NFC transmission range is smaller than RFID

The transmission range of RFID can reach several meters or even tens of meters. However, because NFC adopts a unique signal attenuation technology, NFC has the characteristics of close distance, high bandwidth and low energy consumption compared with RFID. Third, the application direction is different. NFC sees more about consumer electronics devices communicating with each other, and active RFID is better at long-distance identification. With the popularity of the Internet, mobile phones as the most direct intelligent terminal of the Internet will inevitably lead to a technological revolution. As with the previous Bluetooth, USB, GPS and other standard, NFC will become the most important standard for mobile phones in the future, through NFC. Technology, mobile payment, movie watching, and subway rides will play a bigger role in our daily lives.

Sixth, the advantages and characteristics of electronic anti-counterfeiting

1, uniqueness

A truly secure anti-counterfeiting method uses a high-intensity cryptographic algorithm. Each piece of electronic tag data uniquely corresponds to the product and cannot be copied and cannot be forged.

2. Low operating threshold

No need to establish a product database, directly read the electronic tag encryption data, you can achieve anti-counterfeiting, greatly reduce the operating costs of NFC anti-counterfeiting system

3, multiple security

Printing anti-counterfeiting and electronic label anti-counterfeiting.

4, easy to identify

Consumers simply use an NFC phone and are close to the chip to easily identify the authenticity of the product.

5, anti-transfer

The anti-transfer label is attached to the unpacking of the package, and the label is unsealed.

Seven, NFC security label, cosmetics industry application case

1. NFC fragile anti-transfer label for single product, attached to the product or the opening of the package. Due to the variety of cosmetics, the single product packaging is also varied. It is recommended to use the shrinking product and label the label if the label cannot be used. On the contraction;

2. Each NFC Fragile Anti-Transfer Label has a globally unique ID number and cannot be copied and tampered with. NFC fragile anti-transfer labels can achieve the effect of tearing and ruining, and can not be transferred twice. It can fully realize the information management of product production statistics, circulation traceability, sales data, etc.

3, the use of ultra-high frequency electronic tags on the large box of the whole box, can achieve the management of the product in and out of the warehouse, and warehouse inventory problems;

4. The dispatcher and the warehouse use the handheld machine to inquire and track the goods;

5, the courier and consumer terminal query can be read using NFC mobile phone.
