RFID technology goes deep into our lives!Rfid Smart Band Sale

　　If you want to talk about the short-distance Internet of Things network technology, it is estimated that everyone is most familiar with Bluetooth. But in fact, in addition to Bluetooth, RFID radio frequency identification technology has already penetrated into our daily lives, and is even used every day, such as our second-generation ID card.

　　RFID

　　RFID (Radio Frequency Identification, radio frequency identification) is a wireless communication technology that can automatically identify target objects and obtain related data through radio frequency signals. It is one of the commonly used short-range wireless communication technologies in the Internet of Things.

　　RFID electronic tags have a complete set of modulators, encoders, memories, controllers and antennas. According to application requirements, you can choose the built-in battery for use. Compared with ordinary barcodes, RFID technology has the advantages of waterproof, antimagnetic, high temperature resistance, long service life, long reading distance, encryption of label data, and larger storage capacity that ordinary barcodes do not have. The electronic tag can realize the reading, writing and storage of information through the cooperation of the mounted antenna and the reader.

　　Let's take a look at the current applications of RFID technology in the Internet of Things:

　　Warehousing logistics tracking

　　For domestic enterprises, Haier Group has established a fully automated logistics center to optimize supply chain management. By embedding RFID radio frequency identification tags on the box and pallet, when the goods are in or out of the warehouse or stored, the fixed or handheld RFID reader sends a microwave query signal to the RFID electronic tag through the antenna, and the electronic tag responds and returns after receiving the query signal Label data information. After the data is read, the data will be synchronized to the warehouse management platform in real time to improve overall work efficiency.

　　Taking Wal-Mart as an example abroad, the RFID program for pallets and boxes has been implemented, and the effect is remarkable. After implementing the application of RFID technology in its specialty stores, the replenishment speed of goods with electronic tags is three times that of goods using barcode technology, and the collaborative automated ordering system has effectively reduced inventory.

　　Medical item tracking

　　Taking the retrospective management of medical waste as an example, Wanda Information proposed a solution for the supervision and management of medical waste, and designed the "Medical Waste Disposal Supervision and Traceability System" in combination with the medical waste treatment process. After the hospital completes the weighing of the medical waste recycling box, the information is written into the recycling box RFID electronic tag and uploaded to the cloud to synchronize data with the Environmental Protection Agency and the incineration center. After the medical waste recycling bins are delivered to the incineration center, they are weighed again for confirmation.

　　The whole process, using RFID technology, can effectively prevent the loss of medical waste, leakage and accidents. It has been promoted in many medical and health institutions in Shanghai, and has achieved good results.

　　Air baggage check

　　China Eastern Airlines has achieved large-scale baggage tracking through RFID technology. When passengers check their luggage, airport staff will write the flight number, port of departure, port of arrival, departure time, luggage tag number and other information into the RFID tag embedded in the luggage tag. When the luggage tag with the RFID tag is sorted The baggage data information will be automatically collected to the back-end database when each node is installed, installed, arrived, and picked up. For passengers, they can easily check their luggage information through the WeChat applet on their mobile phones.
