Description

  The present invention relates to an RFID card or an RFID label which is an RFID member in which an inlay and a surface base material are laminated and fixed.

  The RFID is also called an IC tag, an RF tag, a wireless tag, an electronic tag, or the like, and is used for the purpose of integrating an object attached with the tag and information related to the object. An inlay is an RFID circuit unit in which an antenna and an IC chip connected to the antenna are fixed on a base film such as PET.

Conventionally, an RFID prepaid card for railway passengers in which an inlay is sandwiched between a surface layer member or a protective member made of a synthetic resin has been put into practical use.
Conventionally, a simple IC tag inlet in which tack paper and an inlay are laminated has been proposed (see, for example, Patent Document 1).

JP 2002-342728 A

A conventional RFID card provided with a surface layer member and a protective member has a certain thickness, is inconvenient to carry, and has a high production cost.
A conventional simple IC tag inlet has a function of an RFID label and / or an RFID card (hereinafter referred to as an RFID member), and since it is thin, it can be easily carried and the production cost can be reduced.

  However, since the conventional simple RFID member is vulnerable to bending and impact, there are cases where an obstacle such as breaking of the IC chip occurs. The RFID member records a number, a symbol, and the like unique to the RFID member on a surface base material such as tack paper so that the RFID member can be reissued when such a failure occurs.

  However, in the case of an RFID member in which an RFID functional failure occurs, the number, symbol, etc. recorded on the surface base material are often unreadable due to scratches over a long period of time. Alternatively, an external force or the like that causes an RFID functional failure may simultaneously make the numbers and symbols recorded on the surface base material unreadable. For this reason, when a conventional RFID member has a functional failure, it may be difficult to reissue it.

  Accordingly, the present invention relates to a simple type, that is, an RFID member having means capable of storing numbers, symbols, and the like recorded on the surface base material with respect to an RFID member that does not have means for resisting bending force or impact force.

Further, the sticker sheet is a tack label having an adhesive layer, and can be attached to paper or the like without using glue, and is more suitable for storage of a copy sheet.

The RFID member according to another preferred embodiment of the present invention is the RFID member according to another preferred embodiment, wherein the contour line of the inlay further becomes the contour line of the spare sheet when the inlay and the spare sheet are overlapped. The mark which shows the safe printing area | region which is the area | region which exists in the inside, and is the area | region where the said inlay laminated | stacked on the lower layer does not exist may be described on the said cutting sheet surface.
In this embodiment, when printing with a dot impact printer or the like, it is easy to print only in the safe printing area, and printing can be performed without applying pressure to the inlay. Printing is possible.

  The present invention described above, preferred embodiments of the present invention, and components included in these can be implemented in combination as much as possible.

  According to the present invention, it is possible to record numbers, symbols, and the like recorded on the surface base material on the copy sheet for a simple type, that is, an RFID member that does not have a means to resist bending force and impact force. Become. The RFID member according to the present invention is thin and convenient for carrying and attaching items. Even if a failure such as breakage of an IC chip occurs while being carried or on an article, it is possible to collate data at the time of issuance based on the record on the copy sheet, and it is easy to reissue the RFID member.

  Hereinafter, an RFID member according to an embodiment of the present invention will be further described with reference to the drawings. The dimensions, materials, shapes, relative positions, etc. of the members and parts described in the embodiments of the present invention are not intended to limit the scope of the present invention only to those unless otherwise specified. It is just an illustrative example.

  FIG. 1 is a diagram for explaining a method of using the RFID member 1. In the RFID member 1 according to the present invention, the same printing is usually performed on the cutting sheet 2 and the surface base material 3. The printed content is, for example, a unique serial number, a symbol, a barcode, a two-dimensional barcode, etc. given to the RFID member, or a combination thereof. Next, the surface base material 3 and the recording sheet 2 are peeled at the adhesion peeling means 4 portion. In this way, it is separated into the RFID member 1a from which the cutting sheet 2 and the recording sheet are peeled off. The recording by the printing may be performed separately on the surface base material 3 and the cutting sheet 2 of the RFID member. The copy sheet 2 is stored as a copy by the issuer or owner of the RFID member. The RFID member 1a from which the recording sheet is peeled is used in the same manner as a conventional simple RFID member (card or label).

  FIG. 2 is an explanatory cross-sectional view of an RFID card 101 which is an RFID member. FIG. 2 is an enlarged view of the thickness direction for ease of understanding and illustration. (FIG. 3, FIG. 4, FIG. 5 and FIG. 7 are also illustrated with an enlarged thickness direction.)

  In the RFID card 101, the surface base material 3 is laminated and fixed on the inlay 13 via the surface base material fixing agent 11. The recording sheet 2 is laminated on the surface base material 3 through the adhesion peeling means 4 so as to be peelable.

  The inlay 13 is formed by applying an adhesive on a resin film (PET film having a thickness of 38 μm), forming a spiral antenna by screen printing using ink containing aluminum, and further electrically connecting an IC chip to the antenna. Connected and fixed. The inlay 13 may be further laminated with synthetic paper, EVA, PET sheet, etc. on one side and / or both sides of the above basic configuration. The inlay 13 may be manufactured by other materials, manufacturing methods, or the like. For example, the resin film may be a polyimide film or a PBT film. The shape of the antenna may be a dipole antenna, for example. The material of the antenna may be copper, for example. The copper foil antenna may be formed by forming a copper foil layer on a resin film and etching it using a resist, or attaching an antenna-shaped copper foil on the resin film by pressing or the like.

  The thickness of the inlay 13 and the surface base material 3 in a laminated and fixed state, that is, the thickness of the inlay 13, the surface base material fixing agent 11 and the surface base material 3 (the thickness is indicated by an arrow 51 in the figure). Is usually 400 μm or less, and from the viewpoint of portability, simplicity and the like, which is the object of the present invention, the thickness is more preferably 300 μm or less, and even more preferably 200 μm or less. The lower limit of the thickness is usually 50 μm.

  The surface of the copy sheet 2 can be printed. Examples of the printable sheet include a heat-sensitive printing copy sheet, a pressure-sensitive printing copy sheet, paper, and a synthetic resin sheet subjected to ink receiving treatment. In the present invention, printing is not limited to entering characters, but includes entering symbols, drawings, pictures, barcodes, and two-dimensional barcodes. Further, in the present invention, printing is not limited to recording using a machine (for example, a printer), but includes recording by writing.

  The cutting sheet 2, the adhesion peeling means 4, the surface base material 3, and the surface substrate base material fixing agent 11 can be prepared as a two-layered tack label. If the tack label is created in this way, the RFID member 1 can be manufactured by attaching the tack label to one side of the inlay 13. Therefore, the possibility that a mechanical and thermal load is applied to the inlay during the manufacturing process is reduced, which is preferable.

  However, the RFID member 1 may be manufactured by sequentially applying and sticking a fixing agent to a constituent (surface base material, inlay, etc.). Further, the surface base material fixing agent 11 may be an adhesive, or may be a hot melt pressure-sensitive adhesive or a hot melt adhesive.

  FIG. 3 is a cross-sectional explanatory view of an RFID label 102 which is an RFID member. The stacked configuration from the inlay 13 to the cut sheet 2 is the same as that of the RFID card 101 described with reference to FIG. A double-sided pressure-sensitive adhesive sheet 18 is laminated and attached to the lower surface of the inlay 13. That is, the double-sided adhesive substrate 15 is laminated on the lower surface of the inlay 13 via the adhesive 14, and the adhesive 16 is laminated on the lower surface of the double-sided adhesive substrate 15. A release paper 17 is laminated and attached to the lower surface of the double-sided pressure-sensitive adhesive sheet 18.

  The inlay 13 is slightly smaller than the double-sided pressure-sensitive adhesive sheet 18 and the surface base material 3, and the surface base material fixing agent 11 and the pressure-sensitive adhesive 14 are in contact with each other at the peripheral portion.

  Thus, regarding the RFID label 102, the double-sided pressure-sensitive adhesive sheet 18 was used as the adhesive layer on the lower surface. Thereby, the RFID label 102 can be manufactured by attaching the two-layered tack label to one side of the inlay 13 and attaching the double-sided pressure-sensitive adhesive sheet to the other side. Therefore, the possibility that a mechanical and thermal load is applied to the inlay during the manufacturing process is reduced, which is preferable. However, in the present invention, the RFID label may be an RFID label in which only one adhesive layer is formed on the lower surface of the RFID card 101 (the lower surface of the inlay 13).

  The RFID card or RFID label which is the RFID member according to the present invention is a simple type. For this reason, an RFID card provided with a protective member is not included. The presence / absence of the protective member is determined by the thickness of the inlay 13 and the surface base material 3 in the laminated and fixed state. That is, an RFID member having a thickness in the range of 50 μm to 400 μm is a simple RFID member.

  From the same point of view, the surface base material after peeling of the cutting sheet is the literal surface of the RFID member. The use of a card or label in which a protective member is further laminated on the surface base material and / or the back surface is not included in the use of the RFID member in the present invention.

  When a double-sided pressure-sensitive adhesive sheet is selected as the pressure-sensitive adhesive layer for the RFID label, the thickness of the double-sided pressure-sensitive adhesive substrate 15 (indicated by an arrow 52 in the figure) is usually 10 μm or more and 100 μm or less. The thickness suitable for the intention of the invention is 10 μm or more and 50 μm or less.

  However, the RFID member that is used after being subjected to the lamination on the surface base material and / or the back surface after the sheet is removed is included in the RFID member according to the present invention. The laminate member is transparent or translucent. Further, the laminate member has a thickness of 150 μm or less. Further, a laminate member that conforms to the intention of the present invention has a thickness of 100 μm or less. In the case of an RFID card, there are cases where the front and back surfaces are laminated, and in this case, a protective member of 300 μm or less is added in combination with the front and back laminate members. The RFID member laminated in this way is still not sufficient to withstand bending force, impact force, etc., is fragile, and has a high degree of need for unique information written on the copy sheet in preparation for reissue Is.

  FIG. 4 is a cross-sectional explanatory view of the surface base material and the recording sheet of the RFID member according to one embodiment. The laminated structure below the thermal printing surface base material 302 which is the surface base material is not shown. On a thermal printing surface substrate 302 that is a surface substrate, a thermal printing copy sheet 202 that is a copy sheet is attached via a pseudo adhesive layer 402 that is an adhesion peeling means. Examples of the thermal printing surface substrate 302 and the thermal printing copy sheet 202 include a thermal transfer ink sheet (a sheet having a porous ink receiving layer such as polyvinyl alcohol or starch on a support sheet) used in the melt thermal transfer recording method. Examples of the support sheet include paper, synthetic paper, and synthetic resin film.

  The pseudo-adhesion is obtained, for example, by laminating a polyolefin on the back surface of the thermal printing copy sheet 202 and then bonding the laminated surface and the surface of the thermal printing surface base material 302 with a molten polyolefin. Examples of the polyolefin used for laminating and melting may include polyethylene and polypropylene.

  The thermal printing surface base material 302 including the surface base material fixing agent 11 and the thermal printing recording sheet 202 can be prepared as a tuck label sheet having a two-layer structure.

  When heat is applied from the surface of the thermal printing copy sheet 202 by a thermal head or the like, the same printing is performed on both the thermal printing copy sheet 202 and the thermal printing surface substrate 302. Thereafter, when the thermal printing copy sheet 202 is peeled off, the pseudo adhesive layer 402 is peeled off, and a sheet having no adhesive on the back surface is obtained as the copy sheet.

  FIG. 5 is a cross-sectional explanatory view of a surface base material and a recording sheet of an RFID member according to another embodiment. The laminated structure below the pressure-sensitive printing surface base material 303, which is the surface base material, is not shown. On a pressure sensitive printing surface base material 303 which is a surface base material, a paper copy sheet 201 which is a copy sheet is attached via a copy sheet adhesive 401 which is an adhesion peeling means. A release layer is attached to the surface of the pressure-sensitive printing surface base material 303 by a release treatment.

  The pressure-sensitive printing surface base material 303 is also called a self-coloring pressure-sensitive recording sheet or self-contained paper, and a step of coating a microcapsule coating material containing a colorless dye (hereinafter referred to as a color former) on a support. And a production method by two-layer coating comprising two steps of coating an electron-accepting substance (hereinafter referred to as a developer) such as acidic clay, phenolic resin, and organic acidic substance on the coating. The above two components or any one component can be microencapsulated, mixed uniformly, and manufactured by a manufacturing method by one-layer coating.

  The pressure sensitive printing surface base material 303 including the surface base material fixing agent 11 and the paper copy sheet 201 can be prepared as a tuck label sheet having a two-layer laminated structure.

  When an ink ribbon or the like is placed on the surface of the paper copy sheet 201 and pressure is applied for printing with a dot impact printer, for example, characters are written on the paper copy sheet 201 with ink from the ink ribbon and pressure sensitive printing is performed. It is printed on the surface of the surface base material 303, and the same character is printed on both. Thereafter, when the paper copy sheet 201 is peeled off, the paper copy sheet 201 is peeled off in a state where the adhesive sheet adhesive 401 is adhered, and becomes a tack label. The sticker sheet as a tack label can be appropriately attached and stored on a sheet such as paper.

  FIG. 6 is a plan view of an RFID member according to another embodiment. On the surface of the paper copy sheet 201, the safe printing area 21 is displayed by surrounding it with a bracket and a short line. The outline of the inlay 13 existing in the lower layer is shown in the figure. The relationship between the shape and size of the inlay 13 and the paper storage sheet 201 is such that when the inlay 13 and the paper storage sheet 201 are overlapped, the contour line of the inlay 13 is inside the paper storage sheet 201 contour line.

  The safe print area 21 is an area where no inlay exists in the lower layer. For this reason, even if an unexpected pressure is applied by the dot printer, the functional failure of the RFID is not caused.

In order to create a safe printing area, as shown in FIG. 6, the inlay may be unevenly distributed with respect to the cutting sheet (the outline of the inlay is brought close to one outline of the cutting sheet). Further, a margin portion generated by using an inlay having a smaller area than that of the copy sheet may be used as a safe print area.
The mark indicating the safe print area may be surrounded by a solid line or a broken line, or may be colored, or may be indicated by a line and an arrow.

  FIG. 7 is an explanatory diagram of an RFID card in which a spacing sheet 31 is added immediately below the inlay. A gap sheet fixing agent 32 and a gap sheet 31 are interposed between the inlay 13 and the double-sided pressure-sensitive adhesive sheet 18. The interval sheet 31 can be prepared as a tack label in which a pressure-sensitive adhesive that is an interval sheet fixing agent is applied on one side. The interval sheet 31 has a through hole 33, and the inlay IC chip 131 is received in the through hole 33.

  The RFID card can be manufactured by sticking a two-layered tack label on one side of the inlay 13, sticking a tack label as a spacing sheet on the other surface of the inlay 13, and sticking a double-sided adhesive sheet. . Employing such a manufacturing method is preferable because it reduces the possibility that a mechanical and thermal load is applied to the inlay during the manufacturing process.

  However, the RFID label may be manufactured by sequentially applying and sticking a sticking agent to a component (surface substrate, inlay, spacing sheet, etc.). The means for laminating and adhering may be an adhesive, or a hot melt pressure-sensitive adhesive or a hot melt adhesive. However, it is impossible to use an adhesive for the adhesion peeling means 4.

  The spacing sheet flattens the surface of the sheet and improves the quality of thermal printing. In addition, the distance between the ink ribbon and the cutting sheet surface when using the dot impact printer can be kept constant.

  The spacing sheet 31 may be provided on the upper surface of the inlay. In this case, the surface where the IC chip of the inlay is raised is turned upward. By providing a through hole in the double-sided pressure-sensitive adhesive sheet 18, the lower surface sheet may serve as a spacing sheet.

  The RFID member according to the present invention can be used for, for example, identification cards, prepaid cards, and the like.
