Medium processing device and image forming device

An image forming device comprising:

• a conveying mechanism;
• a printer configured to form an image on a medium conveyed by the conveying mechanism;
• a radio frequency identification (RFID) device configured to communicate with RFID tags;
• and
• a processor configured to execute a job according to which the processor controls the RFID device to perform a write process on first and second RFID tags of at least one medium conveyed by the conveying mechanism when the first and second RFID tags are moved to a write position along a conveyance path of the at least one medium, and a read process on the first and second RFID tags after the at least one medium is further conveyed along the conveyance path of the at least one medium by the conveying mechanism, wherein
• the RFID device includes an antenna by which the RFID device communicates with the RFID tags and is configured to set a communication range of the antenna to a first communication range during the write process and to a second communication range wider than the first communication range during the read process, and
• the write process includes a first process to write data to the first RFID tag, verify that correct data has been written to the first RFID tag, and display an error guidance and terminate the job when writing of the correct data to the first RFID tag is not verified, and a second process to write data to the second RFID tag, verify that correct data has been written to the second RFID tag, and display an error guidance and terminate the job when writing of the correct data to the second RFID tag is not verified, and the read process includes a third process to further verify that correct data has been written to the first and second RFID tags and display an error guidance and terminate the job when writing of the correct data to the first and second RFID tags is not verified.

A control method for a medium processing device, comprising:

• conveying at least one medium that includes first and second RFID tags along a conveyance path;
• controlling a radio frequency identification (RFID) device to perform a write process on the first and second RFID tags when the first and second RFID tags of at least one medium are conveyed to a write position along the conveyance path;
• controlling the RFID device to perform a read process on the first and second RFID tags by the RFID device after the at least one medium is further conveyed along the conveyance path;
• and
• setting a communication range of an antenna of the RFID device to a first communication range during the write process and to a second communication range wider than the first communication range during the read process,
• wherein the write process includes a first process to write data to the first RFID tag, verify that correct data has been written to the first RFID tag, and display an error guidance and terminate the job when writing of the correct data to the first RFID tag is not verified, and a second process to write data to the second RFID tag, verify that correct data has been written to the second RFID tag, and display an error guidance and terminate the job when writing of the correct data to the second RFID tag is not verified, and the read process includes a third process to further verify that correct data has been written to the first and second RFID tags and display an error guidance and terminate the job when writing of the correct data to the first and second RFID tags is not verified.
