RFID chips, or Radio Frequency Identification chips, are small electronic devices that use radio waves to transmit data. They consist of a microchip and an antenna, allowing them to communicate with a reader device. RFID chips are commonly used for tracking items, managing inventory, and facilitating contactless payments. These chips can be passive, active, or semi-passive. Passive RFID chips do not have their own power source and rely on energy from the reader, while active RFID chips have a battery and can transmit signals over longer distances. RFID technology is widely used in various industries, including retail, logistics, and healthcare.
