RFIDmärgid

RFIDmärgid, or Radio Frequency Identification tags, are small electronic devices that consist of a microchip and an antenna. They are used for tracking and identifying objects, people, or animals. RFIDmärgid operate by transmitting and receiving radio waves, allowing for wireless communication and data transfer. There are three main types of RFIDmärgid: passive, active, and semi-passive. Passive RFIDmärgid do not have a power source and rely on the reader's electromagnetic field for power. Active RFIDmärgid have their own power source, such as a battery, and can transmit signals over longer distances. Semi-passive RFIDmärgid have a power source but rely on the reader's electromagnetic field for powering the microchip. RFIDmärgid are used in various applications, including inventory management, access control, payment systems, and animal tracking. They offer advantages such as contactless operation, multiple tag reading, and the ability to store and retrieve data. However, RFIDmärgid also have limitations, including the need for a reader, potential interference from other electronic devices, and the possibility of data security breaches.
