Patent ID: 8217758

Claim:
An information processing apparatus, comprising: an RFID reader/writer configured to read or write data from or into an RFID portion of an RFID-attached sheet; and a control unit configured to control a speed at which the RFID-attached sheet is transported, wherein the sheet transport speed is changed depending on a read/write communication time required for reading or writing the data from or into the RFID portion of the RFID-attached sheet, wherein the control unit is configured to compare one or more communication speeds at which the RFID portion can operate with one or more communication speeds at which the RFID reader/writer can operate, and select a maximum communication speed from among common communication speeds between the RFID portion and the RFID reader/writer; calculate a read/write communication time required for reading or writing the data from or into the RFID portion from a size of the data and the selected maximum communication speed; calculate a maximum transport speed at which the data can be communicated between the RFID portion and the RFID reader/writer, based on a communication-enabled region that exists along the path of sheet transport, in which region the data can be communicated between the RFID portion and the RFID reader/writer, and based on the calculated read/write communication time, and transport the sheet at the maximum transport speed; and provide a transport-stop period in which the sheet is stopped when the calculated maximum transport speed is lower than a minimum transport speed at which the sheet can be transported stably.
