Patent ID: 8482760

Claim:
A communication apparatus comprising: an image read unit configured to generate image data by reading an image formed on a transmission document; a transmission unit configured to transmit data; a tag read unit configured to wirelessly read tag data stored in an RFID tag provided with the transmission document, the tag data comprising destination data indicating a first destination of the transmission document; a tag write unit configured to wirelessly write data into the RFID tag; an operation unit configured to input a second destination of the transmission document; a comparison unit configured to compare the first destination read from the RFID tag and the second destination input via the operation unit; a transmission controller configured to control the transmission unit based on a comparison result of the comparison unit, wherein, if the first destination and the second destination are different from each other, the transmission controller controls the transmission unit to stop a first transmission of the image data and further controls the tag write unit to write error data indicating that the first transmission of the image data of the transmission document is stopped, into the RFID tag provided with the transmission document; and an error controller configured to stop a second transmission of the image data from the transmission document if the tag read unit reads tag data from the RFID tag provided with the transmission document and the tag data comprises the error data.
