RFID tag, printing paper, printer, and RFID system

Abstract

A radio frequency identification tag to be attached to printing paper includes an upper face that is opposite to a face to be attached to the printing paper, the upper face being made of a paper material substantially equal to the printing paper.

1 . A printer for a radio frequency identification system to draw a character or an image on a printing paper, the printer comprising: 
 a drawing unit that draws the character or the image on the printing paper; and    a communication unit that stores information related to the character or the image in a radio frequency identification tag,    the radio frequency identification system including the printing paper, a reader, and an external apparatus,    the printing paper including the radio frequency identification tag, a first sheet being made of a paper material substantially equal to the printing paper, a second sheet being made of an adhesive material and to be attached to the printing paper, a first protection film disposed between the first sheet and an inlet, a second protection film disposed between the second sheet and the inlet, and an integrated circuit chip and an antenna disposed between the first sheet and the second sheet,    the reader that reads the information stored in the radio frequency identification tag, and    the external apparatus being connected to the reader that displays or outputs the information.    
   
   
       2 . A printing paper for radio frequency identification system, the printing paper comprising: 
 a radio frequency identification tag;    a first sheet being made of a paper material substantially equal to the printing paper;    a second sheet being made of an adhesive material;    a first protection film disposed between the first sheet and an inlet;    a second protection film disposed between the second sheet and the inlet; and    an integrated circuit chip and an antenna disposed between the first sheet and the second sheet,    the radio frequency identification system including a printer, a reader, and an external apparatus,    the printer including a drawing unit that draws the character or the image on the printing paper, and a communication unit,    the communication unit storing information related to the character or the image in the radio frequency identification tag,    the reader that reads the information stored in the radio frequency identification tag,    the external apparatus being connected to the reader that displays or outputs the information, and    the second sheet being attached to the printing paper.    
   
   
       3 . A radio frequency identification tag comprising: 
 a number of turns and a shape of an antenna being optimized in accordance with a size of the radio frequency identification tag,    the radio frequency identification tag being used for the printing paper according to  claim 2 .    
   
   
       4 . An integrated circuit chip comprising: 
 a central processing unit;    a transmission unit; and    a reception unit,    the integrated circuit chip being used for the printing paper according to  claim 2 .    
   
   
       5 . A communication unit being included in the printer according to  claim 1 .  
   
   
       6 . A radio frequency identification tag to be attached to printing paper, comprising an upper face that is opposite to a face to be attached to the printing paper, the upper face being made of a paper material substantially equal to the printing paper.  
   
   
       7 . The radio frequency identification tag according to  claim 6 , wherein the radio frequency identification tag has a total length substantially equal to a width of the printing paper.  
   
   
       8 . Printing paper comprising the radio frequency identification tag as set forth in  claim 6 .  
   
   
       9 . A printer for drawing a character or an image on printing paper including a radio frequency identification tag, the printer comprising: 
 a drawing unit that draws the character or the image on the printing paper; and    a communication unit that writes information related to the character or the image into the radio frequency identification tag.    
   
   
       10 . The printer according to  claim 9 , wherein the printing paper as set forth in  claim 8  is used as the printing paper.  
   
   
       11 . A radio frequency identification system, wherein the radio frequency identification system stores information related to an image or a character drawn on printing paper including a radio frequency identification tag in the radio frequency identification tag, reads the stored information by using an external communication unit, and displays or outputs the stored information by using an external apparatus connected to the external communication unit.  
   
   
       12 . The radio frequency identification system according to  claim 11 , wherein the stored information is character information, sound information, static image information, or moving image information.  
   
   
       13 . The radio frequency identification system according to  claim 11 , wherein the external apparatus is a portable information terminal.
