Consumable authenticity identification and commercial application based on NFC technology

At present, 70% of the water purifiers on the market are based on RO reverse osmosis technology, usually using 4-5 stages of filtration combined with PP cotton, front activated carbon, RO reverse osmosis membrane and post activated carbon. The working principle and filtration precision of the filter elements at all levels are different, and the consumption progress will also vary according to the source water quality and water consumption value of different regions or even different communities. Most of the water purifiers currently on sale provide users with regular replacement services for each filter element ranging from 6 to 36 months through manual recording, or by placing a timer in the machine to Reminder that the filter element is expired.

Manual door-to-door records need to rely on a strong after-sales service system and accurate data transmission. Even for traditional old home appliance brands, it is difficult to be timely and accurate. The secondary pollution caused by the overdue service of the filter element is naturally needless to say, while some other businesses take advantage of consumers' panic about water quality and frequently remind users to replace the filter element. Selling products at low prices, selling filter elements at high frequency and making profits through manual door-to-door services has become a common trick of many small water purifier manufacturers. The huge profits of this type of consumables market also make it a counterfeit target for lawbreakers, resulting in the emergence of the market: under the rampant counterfeit products, the brand reputation is seriously damaged; It leads to the reduction of consumer loyalty, directly affects the interests of enterprises, and disrupts the market structure.

The application of Internet of Things technology brings the possibility of product innovation and solves the problems of product anti-counterfeiting, distribution and after-sales. However, the realization of the purification effect requires profound professional experience and huge industry data. The following is an introduction to the anti-counterfeiting solution for water purifier filter elements based on RFID multi-channel card reading technology. Each RFID tag has a key. This key is written by the user, that is, the brand manufacturer. The key of each chip is different and cannot be read out. Through the authentication algorithm, the uniqueness of the label identity is determined to ensure that the label cannot be copied. The cryptographic security algorithm puts a security lock on the RFID. At the same time, the key of the security lock is held by the manufacturer. The label after the key is issued by the manufacturer cannot be cracked and copied even by the label chip supplier. Brand manufacturers fully grasp the initiative of traceability.


Anti-counterfeit application mode of filter element
1. The reader is installed on the main body of the water purifier.
2. The electronic label is installed on the filter element of the water purifier.
3. When replacing the filter element, the reader-writer on the host will verify the anti-counterfeiting of the filter element.
If the filter element identification is true, the water purifier works normally and records the working time of the filter element. According to the application market, the user is reminded to replace the filter element in time. If the filter element is identified as fake, the water purifier will
alarm and remind the user to replace the genuine filter element to ensure the safety of the user's drinking water and the safety of the water purifier . Solution application mode: one product, one core, one core, one secret, completely eliminate counterfeit and shoddy products 1. Using algorithm-based two-way authentication mechanism, one core and one secret, which can never be read out, ensuring that NFC tags cannot be cloned. 2. No need to connect to the background database , easily realize offline anti-counterfeiting identification, and complete filter element verification 3. The key to the security anti-counterfeiting solution is in the hands of the user, and even the solution provider cannot clone it, reducing the risk of user application
