Definitions

  • the invention relates to radio frequency identification (RFID), particularly to high-frequency-NFC-based anti-counterfeiting tags and systems using the same.
  • RFID radio frequency identification
  • EAS electronic article surveillance
  • the EAS system is essentially composed of a detector, a deactivator and an EAS tag.
  • the detector is disposed at an exit or entrance.
  • Current detectors are also known as security gates. Detectors serve to detect if products without checkout are illegally carried about. Products with EAS tags should be deactivated by the deactivator after having finished checkout and then they can be carried about to legally pass the security gate.
  • Electronic article surveillance is a technological method for preventing shoplifting from retail stores, pilferage of books from libraries or removal of properties from office buildings.
  • Special tags are fixed to merchandise or books. These tags are removed or deactivated by the clerks when the item is properly bought or checked out.
  • a detection system sounds an alarm or otherwise alerts the staff when it senses active tags.
  • These tags are essentially an LC tank circuit that has a resonance peak anywhere from 1.75 MHz to 9.5 MHz.
  • the standard frequency for retail use is 8.2 MHz.
  • Sensing is achieved by sweeping around the resonant frequency and detecting the dip.
  • the EAS tags have no chip.
  • Detection is achieved by sensing harmonics and sum or difference signals generated by the non-linear magnetic response of the material under a mixture of low-frequency (in the 10 Hz to 1000 Hz range) magnetic fields. Demagnetization can be done only by physical destruction or manual removal. Thus, demagnetization boards are disposed on checkout counters of most stores using EAS systems.
  • NFC (Near Field Communication) tags are mostly used for anti-counterfeiting. These tags are attached on merchandise by factories.
  • the NFC derives from RFID (Radio Frequency Identification).
  • NFC is a close-range wireless communication technology, which allows contactless data exchange between electronic devices.
  • An NFC-based anti-counterfeiting system is essentially composed of an NFC system, a communication network and an anti-counterfeiting system.
  • the NFC system includes an NFC tag and an NFC reader (supports smartphones with an NFC function).
  • the NFC tags do not have an anti-tearing function. As a result, many NFC tags are recovered and then attached on fake products. This cause serious damage to manufactures, stores and customers.
  • An object of the invention is to provide a high-frequency-NFC-based product traceability and anti-counterfeiting tag and a product traceability and anti-counterfeiting system including the tag.
  • the high-frequency-NFC-based product traceability and anti-counterfeiting tag of the invention includes a substrate, a first coil formed on the substrate, a second coil formed on the substrate, and an NFC chip fixed on the substrate.
  • a digital signature, product information and a status code whose default value is zero (0) are stored in memory of the NFC chip.
  • the first coil is electrically connected to the NFC chip.
  • the first coil serves as an antenna of the NFC chip.
  • the NFC chip communicates with an NFC reader through the first coil.
  • the NFC reader is capable of reading or writing the status code of the NFC chip through the first coil.
  • the NFC chip has an IO contact and a grounding contact.
  • the IO contact is electrically connected to the grounding contact via the second coil to form a closed loop.
  • the status code keeps at zero (0) when the second coil is not broken to maintain a closed loop.
  • the reader rewrites the status code to be one (1) by way of communication with the NFC chip when the second coil is broken or becomes an open loop.
  • the status code becomes unwritable after the status code has been rewritten to be one (1).
  • the invention also provides a high-frequency-NFC-based product traceability and anti-counterfeiting system which includes a product traceability and anti-counterfeiting tag, an NFC reader and a detector.
  • the product traceability and anti-counterfeiting tag includes a substrate, a first coil formed on the substrate, a second coil formed on the substrate and an NFC chip fixed on the substrate.
  • a digital signature, product information and a status code whose default value is zero (0) are stored in memory of the NFC chip.
  • the first coil is electrically connected to the NFC chip.
  • the first coil serves as an antenna of the NFC chip.
  • the NFC chip communicates with an NFC reader through the first coil.
  • the NFC reader is capable of reading or writing the status code of the NFC chip through the first coil.
  • the NFC chip has an IO contact and a grounding contact.
  • the IO contact is electrically connected to the grounding contact via the second coil to form a closed loop.
  • the status code keeps at zero (0) when the second coil is not broken to maintain a closed loop.
  • the reader rewrites the status code to be one (1) by way of communication with the NFC chip when the second coil is broken or becomes an open loop.
  • the status code becomes unwritable after the status code has been rewritten to be one (1).
  • the NFC reader communicates with the NFC chip through the first coil and is capable of reading or writing the status code.
  • the detector is used for detecting the second coil and is capable of raising an alarm when the second coil is a closed loop.
  • the second coil is an EAS coil.
  • both the first coil and the second coil are separately formed on the same side of the substrate.
  • the NFC reader sends a command to the NFC chip to disconnect the second coil to be an open loop when the NFC reader rewrites the status code to be one by way of communication with the NFC chip.
  • the IO contact is grounded to form a low level and the NFC reader rewrites the status code to be one by way of communication with the NFC chip, the NFC reader sends a command to the NFC chip 40 to switch an output switch of the IO contact to be a high level and the IO contact disconnects the grounding contact.
  • FIG. 1 is a structural schematic view of the high-frequency-NFC-based product traceability and anti-counterfeiting tag of the invention.
  • the high-frequency-NFC-based product traceability and anti-counterfeiting tag 10 includes a substrate 20, a first coil 31 and a second coil 32 formed on the substrate 20, and an NFC chip 40 fixed on the substrate 20.
  • the substrate can be made of paper or a plastic film.
  • a digital signature, product information and status code whose default value is zero (0) are stored in memory of the NFC chip 40.
  • Customers or dealers can use an NFC reading device or a smartphone with an NFC function to read the digital signature and/or product information for product traceability and anti-counterfeiting.
  • the first coil 31 is electrically connected to the NFC chip 40. As shown in FIG. 2 , the first coil 31 electrically connects to antenna contacts 41, 42 to serve as an antenna of the NFC chip 40.
  • the NFC chip 40 is able to communicate with an NFC reader 50 through the first coil 31 as shown in FIG. 3 .
  • the NFC reader 50 is capable of reading or writing the status code of the NFC chip 40 through the first coil 31.
  • the NFC chip 40 has an IO (input/output) contact 43 and a grounding contact 44.
  • the IO contact 43 is electrically connected to the grounding contact 44 via the second coil 32 to form a closed loop.
  • An embodiment of the second coil 32 is an EAS coil.
  • the EAS system will be triggered to raise an alarm when the second coil 32 without demagnetization passes an anti-counterfeiting gate.
  • the status code keeps at zero (0) when the second coil 32 is not broken to maintain a closed loop.
  • the NFC chip 40 rewrites the status code to be one (1) when the second coil 32 is broken or becomes an open loop.
  • the status code becomes unwritable after the status code has been rewritten to be one (1).
  • both the first coil 31 and the second coil 32 are separately formed on the same side of the substrate 20.
  • the second coil 32 is breakable.
  • the substrate 20 may be provide with a tearing line 21 for tearing or separating.
  • the tearing line 21 crosses the second coil 32.
  • the second coil 32 can be broken when the substrate 20 is torn or separated along the tearing line 21.
  • the NFC reader 50 sends a command to the NFC chip 40 to disconnect the second coil 32 (i.e., EAS coil) to form an open loop.
  • the second coil 32 i.e., EAS coil
  • the IO contact 43 is grounded to form a low level
  • the NFC reader 50 sends a command to the NFC chip 40 to switch an output switch of the IO contact 43 to be a high level and the IO contact 43 disconnects the grounding contact 44 while the NFC reader 50 is rewriting the status code to be one (1) by way of communication with the NFC chip 40.
  • the second coil 32 is disconnected through the NFC chip 40 when a product P has checked out. That is, both checkout and releasing the anti-counterfeiting mechanism can be simultaneously finished. An additional operation of demagnetization or releasing the anti-counterfeiting mechanism is not required. This can effectively increase efficiency of cashiers.
  • FIG. 3 is a schematic view of the high-frequency-NFC-based product traceability and anti-counterfeiting system of the invention.
  • the system includes a product traceability and anti-counterfeiting tag, an NFC reader 50 and a detector 60.
  • the NFC reader 50 communicates with the NFC chip 40 through the first coil 31 and is capable of reading or writing the status code.
  • the NFC reader 50 further connects to a POS (point of sales) system to implement synchronous demagnetization or releasing the anti-counterfeiting mechanism of the product traceability and anti-counterfeiting tag 10 when a product P has checked out.
  • the detector 60 is used for detecting the second coil 32 and is capable of raising an audio or light alarm when the second coil 32 is a closed loop.
  • FIGS. 4-6 are schematic views of various using statuses of the high-frequency-NFC-based product traceability and anti-counterfeiting tag of the invention.
  • FIG. 4 depicts a first status where a product P with the product traceability and anti-counterfeiting tag 10 is not checked out yet, the second coil 32 as an EAS coil is not broken or demagnetized, and the status code is zero (default value).
  • FIG. 5 depicts a second status where the second coil 32 as an EAS coil has been broken to be an open loop, the IO contact 43 cannot be electrically connected to the grounding contact 44through the second coil 32, the NFC chip 40 detects that the IO contact 43 is floating, and the status code is rewritten to be one by the NFC chip 40.
  • FIG. 6 depicts a third status where the product P has been checked out, the NFC reader 50 sends a command to the NFC chip 40 to disconnect the second coil 32 (i.e., the EAS coil) to form an open loop, and the NFC chip 40 rewrites the status code to be one and the status becomes unwritable.
  • the status code becomes unchangeable after the NFC reader 50 sends a command to the NFC chip 40 to change the status code as one.
  • the status code is still one even if the tag 10 is reused. As a result, the tag 10 has an anti-reuse function.
  • Status code "1" means the product having been checked out or the second coil 32 having been broken. If the tag 10 of the invention is reused, dealers or customers can know if a product is problematic by reading the status code.
  • the invention integrates an NFC tag and an EAS coil/tag to be one piece to implement product traceability, anti-tearing and anti-counterfeiting.
  • the tag 10 has had the EAS function, so the process of attaching EAS tags can be saved.
