Abstract
An IC tag read-write apparatus includes a control circuit, a transmission link, and a plurality of antenna units. The control circuit controls data relative to an outgoing carrier wave and an incoming carrier wave. The antenna units correspond to a plurality of IC tags. Each of the antenna units includes a modem, a first antenna, and an indication circuit. The modem is connected to the control circuit through the transmission link and modulates the carrier wave based on the data in a data writing operation and demodulates the incoming carrier wave in a data reading operation. The first antenna sends the modulated carrier wave by air to a second antenna of a corresponding one of the IC tags. The indication circuit generates property information with respect to the antenna unit.
