RFID water purifier filter element and printer toner cartrid

Anti-counterfeiting of consumables is a commonplace topic. At present, the profits of consumables in many industries have attracted a large number of vendors who know of counterfeiting. Repeated prohibitions have continued. The emergence of RFID consumables anti-counterfeiting technology can protect the interests of brand merchants and consumers to a large extent, and solve after-sales problems. Today, let’s take a look at the specific case application analysis of RFID technology in the anti-counterfeiting of water purifier filter elements and the anti-counterfeiting of printer toner cartridges with Shenzhen Yongxin IoT Technology.

 

Case 1: Anti-counterfeiting RFID embedded filter element of water purifier

 

With the continuous improvement of people's health awareness and the upgrading of consumption concepts, products such as water purifiers and air purifiers have gradually entered the homes of ordinary people from large-scale construction sites, becoming one of the secondary needs of family life consumption. These products are different from traditional home appliances. They mainly rely on filters and filter elements that need to be replaced frequently to maintain the purification function, and the purification of pollutants is not visible to the naked eye, which is an important gap for many unscrupulous businesses to profit from.

 

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

 

Manual door-to-door recording needs to rely on a powerful after-sales service system and accurate data transmission, even for traditional old-brand household appliances brands, it is difficult to be timely and accurate. Naturally, the secondary pollution caused by the filter element’s overdue service does not need to be said. Other businesses use consumers’ panic about water quality to frequently remind users to replace the filter element. Selling products at low prices, high-frequency sales of filter elements and manual door-to-door services to earn profits has become a common tactic of many small water purifier manufacturers. The profit of this type of consumables market also makes it a fraud target for criminals, resulting in the emergence of the market: counterfeit goods are rampant, brand reputation is seriously damaged; fake goods are difficult to distinguish authenticity, seize the market, and consumer interests are damaged; directly lead to consumption Low consumer loyalty directly affects corporate interests and disrupts the market structure.

 

The application of the Internet of Things and rfid technology has brought the possibility of product innovation to solve product anti-counterfeiting, distribution and after-sales problems. At present, many pioneering companies have begun to use the core IoT RFID embedded filter anti-counterfeiting technology for product anti-counterfeiting.

The specific plan is as follows:

 

An RFID embedded consumable anti-counterfeiting read-write module is built in the water purifier (it needs to be designed during production and RFID tags are attached to all filter elements).

The RFID tag is activated when it leaves the factory, and the algorithm is inserted. When the filter element is used, the read-write module of the water purification equipment must read the valid RFID tag and verify its algorithm. The effective filter element can be identified as true and the water purifier works normally And record the working time of the filter element, the filter element is identified as false, the water purifier alarms, prompting the user to replace the original filter element, to ensure the user's drinking water and water purifier work safety.

 

After the filter element is used for a certain period of time (or reach the end of its life), the device automatically reminds the user to replace a valid filter element, otherwise it will stop working. When the user installs a new filter element, the device reads the valid label and can work after verification.

 

Moreover, as an ordinary consumer, you can use an NFC mobile phone to check the counterfeit of the filter element online, which effectively protects the rights and interests of ordinary consumers.

 

Each tag has a key, which is written by the user, that is, the brand manufacturer. The key of each chip is different and cannot be read. Through the authentication algorithm, the identity of the label is determined, and the label cannot be copied. The cryptographic algorithm is equivalent to putting a lock on the RFID. At the same time, the key of the lock is controlled by the manufacturer. The label after the manufacturer has issued the key cannot be cracked and copied even by the label chip supplier. Brand manufacturers can grasp the initiative of traceability.

 

The advantages of using the RFID filter element anti-counterfeiting system of the core IoT are:

1. Using algorithm-based two-way authentication mechanism, one core and one secret, which can never be read, to ensure that RFID tags cannot be cloned;

2. No need to connect to the back-end database, easily realize offline anti-counterfeiting identification, and complete the filter element verification;

3. The key of the anti-counterfeiting solution is in the hands of the user, even the solution provider cannot clone it, reducing the user's application risk;

 

Case 2: Anti-counterfeiting of printer toner cartridges

 

Commonly used consumables for laser printers are toner cartridges. Toner cartridges are disposable consumables and need to be replaced after a period of use. Because of their relatively high price, they attract the attention of many counterfeiters. Therefore, they will inevitably appear in the market. There are a lot of fakes of all kinds. At present, the toner cartridges on the market are mixed, and if you are not careful, you will buy fake and inferior products. Fake toner cartridges have brought us a lot of damage both economically and at work. Rongzhixing RFID consumables management can solve this problem.

 

1. The built-in RFID tag on the toner cartridge, the special card issuer writes the permission matching information

2. Install an RFID card reader on a specific part of the printer. When replacing the toner cartridge, you can only use the built-in RFID authorization label, otherwise the printer will not work normally.

3. The RFID tag has a designated UID and a large-capacity user data area, and has an independent management key, which can trace the source of the item and correctly find a specific provider. When the product fails, you can also quickly seek after-sales service.

4. It can prevent suppliers or distributors in different regions from collaborating with each other

5. It can protect and maintain the good integrity brand effect of the product
