Common RFID in life, we don't know

Speaking of RFID, many people don't know what it is. The professional introduction is like this. RFID (Radio Frequency Identification System) is a non-contact automatic identification system, which automatically identifies target objects through radio frequency wireless signals and obtains relevant data. It is composed of electronic tags, readers and computer networks.


In fact, this kind of technology is very common in life, medical care, food, transportation, etc., all have his shadow.

First of all, at the moment when everyone falls to the ground, the biggest thing is to register him with a household registration. When he grows up, he must apply for an ID card. The current second-generation ID card uses RFID. The reason why our ID card can be sensed is because the RFID chip is embedded in the ID card. After the ID card enters the sensing range of the reader, the chip and the radio frequency signal sent by the reader are electronically sensed. The information is transmitted to the reader, and the reader sends the acquired data to the data processing center for decoding.

Secondly, most people will use access control cards, including campus cards, community cards, company cards, etc. In fact, RFID is also used on each access control card, which contains personal information. When the access control card touches the sensor, the sensor transmits the information of the access control card to the system for matching, and when it senses the existence of the information, the door will be opened.

When you drive out of the parking space, have you ever thought about how the system detects and how to charge? This is actually the application of RFID technology. Through the writing of information on the RFID tag, the tag information is read without contact using radio frequency technology, and then the information is automatically processed.


Now, when we carry out nucleic acid detection, the staff's scanning code also uses RFID technology. Whether it is mixed sampling or single sampling, each test tube has a barcode on it, the barcode needs to record some identity information of the person, and the RFID label detection will encapsulate a label element at the bottom of the test tube, and the identity information is readily available before the measurement. Existing on the component, low-cost digital sample management can be performed in one step.

In the current era, online shopping is a very common thing, followed by the transportation problem of express delivery. It is necessary to achieve precision and protect privacy. Therefore, RFID is also essential.


RFID technology is applied to the logistics list, as long as the mailer fills in the relevant logistics information on the platform provided by the logistics enterprise before mailing the item. When collecting mail, the picker only needs to scan the RFID logistics list with the scanning device, and mark the express as the pick-up state. During the sorting process, if the robot is used for automatic sorting, the robot directly follows the information in the RFID for automatic sorting; if it is manual sorting, the sorter uses the instrument to scan the information in the RFID to sort according to the information. RFID is also at work when receiving express delivery.

Therefore, the application of RFID in life is very extensive and very common.

    The RFID reader (reader writer) communicates wirelessly with RFID electronic tags through an antenna, enabling the reading or writing of tag identification codes and memory data. A typical reader includes a high-frequency module (transmitter and receiver), a control unit, and a reader antenna.

    The anti removable ceramic RFID electronic tag uses a composite ceramic substrate inside, which is resistant to high temperature and has stable performance. Ceramic labels are inherently fragile, making them highly suitable for applications that prevent disassembly and tearing. The combination of anti disassembly ceramic labels with automotive glass can achieve excellent readability performance.
