RFID tag how does RFID tag input data?
RFID tags, also known as radio frequency tags, realize the spatial (contactless) coupling of radio frequency signals through the coupling elements between the tags and readers, and realize energy transmission and data exchange according to the timing relationship in the coupling channel. How does RFID tag input data?
How does RFID tag input data? The data of RFID electronic tag can be read and written effectively through the programmer. Readers/readers (readers that can read/write) can also effectively read and write data from RFID electronic tags.
RFID reader is also mobile and fixed. At present, RFID technology has been widely used, such as library, access control system, food safety traceability and so on.

Radio frequency identification technology, also known as radio frequency identification, is a communication technology. It can identify specific targets and read and write relevant data through radio signals, without mechanical or optical contact between the identification system and specific targets.
RF is generally microwave, 1-100ghz, which is suitable for short-range identification communication.
Radio frequency tag is the physical carrier of product electronic code (EPC). It is attached to the tracked project and can be circulated and read and written around the world.
Conceptually, RFID is similar to bar code scanning. For bar code technology, RFID is used to attach the encoded bar code to the target and use a dedicated scan reader to transmit the bar magnetic information to the scan reader; RFID uses a dedicated RFID reader and a dedicated RFID tag that can be attached to the target object, and sends information to the RFID reader through the frequency signal through the RFID tag.

RFID tag how does RFID tag input data?
In the technical field, the transponder initially refers to an electronic module capable of transmitting information and replying to information. In recent years, with the rapid development of RF technology, the transponder has a new meaning. Also known as smart tags or tags. RFID tag reader communicates with RFID tag wirelessly through antenna. RFID technology can identify high-speed moving objects and multiple tags at the same time, which is fast and convenient to operate.
The transponder is composed of antenna, coupling element and chip. Generally, tags are used as the transponder. Each tag has a unique electronic code and is attached to an object to identify the target object.
Reader: a device composed of antenna, coupling element, chip, reading (sometimes writing) tag information, which can be designed as a handheld RFID reader/writer or a fixed reader/writer.

Application software system: it is application layer software, which is mainly used to further process the collected data for people to use.
The reader can be a read or read/write device according to the structure and technology used. It is the information control and processing center of the RFID system. The reader is usually composed of coupling module, transceiver module, control module and interface unit. Half duplex communication mode is generally used for information exchange between reader and transponder, and reader provides energy and timing for passive transponder through coupling. In practical applications, the management functions of object recognition information collection, processing and remote transmission can be further realized through Ethernet or WLAN. Balise is the information carrier of RFID system. Balise is mostly a passive unit composed of coupling elements (coil, microstrip antenna, etc.) and microchip.
RFID is a flexible application technology which is easy to operate, simple and practical, and especially suitable for automatic control. It can work freely in various harsh environments: short-range RF products are not afraid of oil stains, dust pollution and other harsh environments, and can replace bar codes, such as tracking objects on the factory assembly line; Long distance RF products are mostly used in transportation, and the recognition distance can reach tens of meters, such as automatic charging or vehicle identification.
