What is RFID? RFID 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. RFID technology is very common in life, and has its shadow in medical, food, transportation and other fields.
First of all, the ID card is the credential for each of us to identify and record personal information, and it applies RFID technology. 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, such as campus cards, community cards, company cards and so on. 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 the information is sensed, the door will be opened. And how is the parking system detected and how is it charged? 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.
Due to the current epidemic, when we conduct nucleic acid testing, RFID technology is also applied to the scanning code of the staff. 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 information age, online shopping is becoming more and more common, and express delivery needs to be precise and privacy protected. Therefore, RFID technology is applied to the logistics list, as long as the sender fills in the relevant logistics information on the platform provided by the logistics enterprise before mailing the item. When collecting the mail, the picker only needs to scan the RFID logistics list with the scanning device, and mark the express as the pick-up state. In the sorting process, if the robot is used for automatic sorting, the robot directly performs automatic sorting according to the information in the RFID; if it is manual sorting, the sorter uses the instrument to scan the information in the RFID and sort according to the informatioTo sum up, the application of RFID in life is very extensive and can be seen everywhere.
