Definitions

  • the present invention relates to a radio-frequency identification tag with a securing portion.
  • a radio frequency identification (RFID) tag is a tag provided with a transponder comprising an antenna and an integrated circuit attached to the antenna.
  • RFID tags do not necessarily have an internal power supply or battery of their own but the power required to energize the tag is obtained from the electromagnetic field created by the reader device used to interrogate the tag. Such tags relying purely on backscatter communication are referred to as passive tags.
  • RFID tags can be used in various environments where identifica- tion is needed.
  • One important application area of RFID tags is packaging of products, such as beverage bottles.
  • RFID tags may be attached to packages and used for identifying the products at various stages of supply chain.
  • RFID labels are typically attached to the package by strong adhesive.
  • US6050622 discloses a safety sealing device including a support. An electronic safety circuit is glued to one face of the support. The electronic safety circuit includes a winding of fine wire connected to an electronic component. The electronic component is activated and interrogated by outside checking means via the winding, which acts as an antenna. The electronic compo- nent may be coded so that it responds to the interrogation with its code.
  • the safety sealing device may further comprise differentiated gluing means. When attempting to tamper with the support to which the safety circuit has been glued in order to unseal a receiving article, the attempt at ungluing or a tearing causes a break in the continuity of the electronic circuit. As a result, the elec- tronic component no longer responds to an interrogation with its code, which indicates that the safety sealing device has been tampered with.
  • a radio-frequency identification tag with a transponder comprising at least an antenna structure and an integrated circuit coupled with the an- tenna structure, the identification tag further comprising a securing portion for securing the identification tag to an article, wherein the securing portion is at least partly of shape change material that can be activated to undergo a shape change of substantially permanent nature.
  • the securing portion comprises heat- shrinkable material.
  • the securing portion comprises electronic tamper detection means connected to the integrated circuit, such as a galvanic tamper loop separate from the antenna.
  • the integrated circuit may be configured to detect break of the tamper loop.
  • the integrated circuit may be configured to return, after detecting the break of the tamper loop, a specific code to indicate tampering during tag reader interrogation.
  • Figure 1 is a schematic top view of an example radio-frequency identification tag
  • Figure 2 is a schematic side view of an example radio-frequency identification tag
  • FIGS 3 and 4 illustrate top views of example radio-frequency identification tags
  • FIGS 5 to 7 illustrate some examples of radio-frequency identification tags attached to articles.
  • Figure 8 illustrates an apparatus for producing electronic components according to an embodiment.
  • FIG. 1 illustrates a radio-frequency identification (RFID) tag 1 with a transponder 4 on one portion 3 of the tag.
  • the transponder 4 comprises at least an antenna structure 6 and an integrated circuit (IC) 5 coupled with the antenna structure.
  • the IC 5 may be connected to the antenna structure 6 directly or via a module with required electrical connections.
  • the IC 5 may com- prise an analogue RF interface block with a modulator and demodulator, digital control logic, and a memory, such as electrically erasable programmable readonly memory (EEPROM) storing at least identification data.
  • the RF interface block may comprise a rectifier providing supply voltage.
  • the tag 1 further comprises a securing portion 2 for securing the identification tag to an article.
  • the securing portion 2 is at least partly of a shape change material that can be activated to undergo a shape change of substantially permanent nature to attach the tag 1 to an article, such as a bottle, a pharmaceutical package, a food package, etc.
  • a shape change material that can be activated to undergo a shape change of substantially permanent nature to attach the tag 1 to an article, such as a bottle, a pharmaceutical package, a food package, etc.
  • heat- shrinkable plastic is activated to tighten the securing portion 2 around a neck of a bottle as illustrated in Figure 5.
  • the securing portion 2 can be a fixed part of the RFID tag 1 and the RFID tag may comprise all attachment means required for attaching the RFID tag to the article. For example, no further attachment caps or the like need to applied for securing the RFID tag around a neck of a bottle.
  • the RFID tag may be attached to the article without adhesives. This is particularly advantageous for food or beverage products where use of possibly noxious material cannot be tolerated due to healthy reasons. Further, in case of recyclable glass bottles and similar containers, all items attached to the bottle typically need to be fully removable (washable) from the bottle to ensure good recyclability without any residues left on the container.
  • the RFID tag can be manufactured substantially as a planar and dry product (without adhesive). Planarity is important for roll- to-roll type web manufacturing processes and production and storaging of dry products is easier as compared to that of non-planar and/or "wet" products.
  • the RFID tag 1 comprises all necessary elements for attachment, it is not necessary to add further layers for attachment at the stage of attaching the tag to the article e.g. in a bottling plant. Hence, less complex system is required for automatic tag attachment as compared to applying further affixing layers and/or adhesives at the attachment stage.
  • FIG. 2 illustrates an example side view of an RFID tag, in which the transponder 4 is provided on a substrate 20.
  • polyester PET
  • the substrate 20 may be flexible and/or comprise e.g. cuts, perforations or thinned portions at least within the securing portion 2 as appropriate to enable coupling to the article.

  • a shape change material layer such as a heat-shrinkable plastic film, may extend also on the trans- ponder portion 3.
  • the securing portion 2 may form a seal between the portions of the article.
  • the securing portion 2 may form a seal between a mouth and a neck of a bottle, or between a cover and side of a cardboard package.
  • the fastened securing portion 2, with the activated shape change material that has undergone the shape change of substantially permanent nature may be applied as a tamper indicator.
  • the secured tag 1 may serve as a tamperproof RFID tag, since it is at least difficult to detach the secured tag 1 from the article intact.
  • the securing portion 2 comprises electronic tamper detection means, such as a specific tamper loop 30 connected to the integrated circuit 5.
  • the tamper loop 30, which may also be referred to as a tamper-evidence loop, may be any kind of galvanically connected structure, the break of which can be detected by the IC 5.
  • the tamper loop may be of aluminum, copper, silver, conductive polymeric material, or another suitable conductive material. In many cases the tamper loop can implemented by etching a conducting structure of a metal film on a polymer substrate. The shape change material, such as heat-shrinkable plastic film may then be laminated on the substrate and the conductive structure.
  • the IC 5 comprises specific connectors for the tamper loop 30.
  • Conductive materials having at least some elasticity may be applied in the areas in which the shape change material 21 is applied.
  • the tamper loop 30 may be implemented by conductive ink or paste, or another suitable conductive material with some elasticity.
  • the RFID tag Since the tamper loop 30 is separate from the antenna 6, the RFID tag may still be operative after tampering and the original information may be readable by an RFID tag reader.
  • the integrated circuit 5 may be configured to detect break of the tamper loop 30. After detecting the break of the tamper loop, at least one indicative bit may change status in the integrated circuit 5, and the integrated circuit 5 may configured to return a specific code to indicate tampering during tag reader interrogation.
  • the tamper loop 30 may serve as a secondary (booster) antenna. Although the secondary antenna structure is broken when the RFID tag is tampered, the RFID tag may still be connected via the primary antenna 6.
  • the RFID tag 1 and the IC 5 may be configured with various further features, such as storage of further use data, data transfer mode, external power supply, etc.
  • the tamper loop connector(s) or further connector(s) of the IC 5 may be applied for receiving data from an external module, such as an active sensor module.
  • the RFID tag 1 may be configured to function as an intermediate data storage and wireless data transmission device.
  • the securing portion 2 comprises heat- shrinkable material (or for some applications heat-expansible material may be applied) and the shape change is activated by increased temperature.
  • heat- shrinkable material or for some applications heat-expansible material may be applied
  • the shape change is activated by increased temperature.
  • hot air nozzle or infrared heating may be applied in a packaging system to finally secure the RFID tag connected to the article.
  • the permanent form shaping can take place in temperatures low enough not to cause any harm to the other components of the RFID tag 1 . It becomes possible to perform the application of the RFID tag quickly and easily and to achieve high application (tagging) speeds.
  • Various types of commercially available heat-shrinkable plastics are applicable for many tagging applications.
  • shape change materials may be applied and the shape change may be activated by any other suitable trigger, such as ultraviolet light or some other electromagnetic radia- tion.
  • shape-memory polymers are applied as the shape change material.
  • Shape-memory polymers refer generally to polymers specifically programmed to go from a predefined shape to another in response to trigger(s) such as temperature, light or magnetic field. Such shape-memory polymers may have a first temporary shape and a second permanent state. However, the shape-memory polymers may be able to change their shape multiple times, and the shape-change material may include two or more types of polymers with distinct melting points.
