Abstract
A wireless communication system includes a storage apparatus and a computing device. The storage apparatus includes a connector, a wireless antenna, a nonvolatile first memory having stored therein visual or audio content, a communication controller powered from an induction current generated when a wireless signal is received through the wireless antenna, and a controller powered using the power supplied from the electronic apparatus through the connector. The controller retrieves the visual or audio content from the first memory based on content ID transmitted wirelessly from the computing device and transmits the retrieved visual or audio content to the electronic apparatus for playback by the electronic apparatus. The computing device includes an image capturing unit, extracts feature values from the data of the captured image, and transmits the wireless signal containing the content ID to the storage apparatus, the content ID being determined from the extracted feature values.
