1. What is RFID?
RFID is the abbreviation of Radio Frequency Identification, which is radio frequency identification. Often referred to as inductive electronic chips or proximity cards, proximity cards, contactless cards, electronic tags, electronic bar codes, and so on. A complete RFID system consists of two parts, Reader and Transponder. The principle of operation is that the Reader transmits a certain frequency of infinite wave energy to the Transponder, which is used to drive the Transponder circuit to send the internal ID code. At this time, the Reader receives the ID. Code. The speciality of Transponder is that it is free of battery, contact-free, and free of card, so it is not afraid of dirt, and the chip password is the only one in the world that cannot be copied, with high security and long life.
The application of RFID is very extensive. At present, typical applications include animal chips, car chip alarms, access control, parking lot control, production line automation, and material management. There are two types of RFID tags: active tags and passive tags.
2. What is an electronic label?
The electronic label is RFID, and some are called radio frequency label and radio frequency identification. It is a non-contact automatic identification technology. It recognizes the target object and acquires relevant data through radio frequency signals. The identification work does not require manual intervention. As a wireless version of the barcode, the RFID technology has the waterproof, antimagnetic and high temperature resistance that the barcode does not have. Long service life, large reading distance, data on the label can be encrypted, storage data capacity is larger, and storage information can be changed freely.
3. What is RFID technology?
RFID radio frequency identification is a non-contact automatic identification technology. It automatically recognizes target objects and acquires relevant data through radio frequency signals. The identification work can work in various harsh environments without manual intervention. RFID technology can recognize high-speed moving objects and recognize multiple labels at the same time, which is quick and easy to operate.
Short-range RF products are not afraid of harsh environments such as oil stains and dust pollution. Bar codes can be replaced in such environments, such as tracking objects on the assembly line of a factory.
Long-range RF products are mostly used for transportation, and the recognition distance can reach several tens of meters, such as automatic charging or identification of vehicle identity.
