Detailed Description
The positional relationship described in the following embodiments includes: the top, bottom, left and right, unless otherwise indicated, are based on the orientation of the elements in the drawings.
Fig. 1 is a schematic structural diagram of an embodiment of an anti-counterfeiting tracing anti-theft tag based on a high-frequency NFC mechanism according to the present invention. The anti-counterfeiting tracing anti-theft label 10 based on the high-frequency NFC mechanism comprises: a substrate 20, a first coil 31 and a second coil 32 formed on the surface of the substrate 20, and an NFC chip 40 fixed on the surface of the substrate 20; the material of the base material 20 can be any one of paper and plastic film; the storage of the NFC chip 40 stores a digital signature, product information, and a status code with a default value of 0, and a consumer or a manufacturer can read the digital signature and/or the product information through an NFC reading device or a mobile phone supporting an NFC function, thereby implementing the functions of tracing to the source and preventing counterfeiting of the commodity.
Wherein the first coil 31 is electrically connected to the NFC chip 40, as shown in fig. 2, in an embodiment, the first coil 31 is electrically connected to antenna interfaces 41 and 42 of the NFC chip, the first coil 31 serves as an antenna of the NFC chip 40, the NFC chip 40 can communicate with an NFC reader 50 through the first coil 31 (see fig. 3), the NFC reader 50 can read/write the aforementioned status code of the NFC chip 40 through the first coil 31, the NFC chip 40 has an IO interface 43 and a Ground (GND) interface 44, the IO interface 43 is electrically connected to the ground interface 44 through the second coil 32 to form a closed loop (closed loop), where an embodiment of the second coil 32 is an EAS coil, that is, when the second coil 32 passes through a security gate of a shopping mall in an un-demagnetized state, the EAS system is triggered to issue an alarm; the state code remains 0 when the second coil 32 is not broken and remains in a closed loop, and the NFC chip 40 rewrites the state code to 1 when the second coil 32 is broken or becomes an open loop.
As a preferred configuration of the anti-counterfeiting tracing anti-theft label based on the high frequency NFC mechanism, the first coil 31 and the second coil 32 are formed on the same side surface of the substrate 20 in a side-by-side relationship, and the second coil 32 can be broken, for example, when the substrate 20 is designed with a tear line 21 that can be torn or torn, and the tear line 21 and the second coil 32 intersect on a projection plane, or the tear line 21 transversely passes through the projection plane of the second coil 32, the second coil 32 can be broken while the substrate 20 is torn or torn along the tear line 21.
As an embodiment of the anti-counterfeiting tracing anti-theft tag based on the high-frequency NFC mechanism, the NFC reader 50 writes the state code into 1 by communicating with the NFC chip 40, and simultaneously sends a command to the NFC chip 40 to turn off the second coil 32 (i.e., the EAS coil) to form an open loop. In a specific embodiment, when the second coil 32 is not damaged and remains in a closed loop, the IO interface 43 is grounded to a default low level, the NFC reader 50 rewrites the state code to 1 through communication with the NFC chip 40, and at the same time, the NFC reader 50 sends an instruction to the NFC chip 40 to switch the output switch of the IO interface 43 to a high level, so that the IO interface 43 is disconnected from the ground interface 44. Therefore, the commodity P can be disconnected from the second antenna 32 through the NFC chip 40 while the checkout is finished, the function of checkout and the anti-theft mechanism removal are achieved, the demagnetization or the anti-theft mechanism removal operation is not needed again, and the working efficiency of a cashier is improved.
Fig. 3 is a functional block diagram of an embodiment of an anti-counterfeiting traceability anti-theft system based on a high-frequency NFC mechanism according to the present invention. An implementation mode of an anti-counterfeiting tracing anti-theft system based on a high-frequency NFC mechanism comprises the following steps: the anti-counterfeiting tracing anti-theft label comprises an anti-counterfeiting tracing anti-theft label 10, an NFC reader-writer 50 and a Detector 60 (Detector).
The NFC reader 50 may communicate with the NFC chip 40 through the first coil 31, and perform read/write operations on the aforementioned status code; as a preferred embodiment of the anti-counterfeiting tracing anti-theft system of the present invention, the NFC reader 50 is further connected to a Point of sale (POS) system, so as to perform operations of demagnetizing or deactivating the anti-counterfeiting tracing anti-theft tag 10 attached to the commodity P while the commodity P is being checked out. The detector 60 is used to detect the second coil 32, and generate an alarm when detecting that the second coil 32 is a closed loop, such as an alarm generated by sound and/or light, to achieve the purpose of anti-theft.
Please refer to fig. 4 to fig. 6, which are schematic diagrams illustrating several usage states of the anti-counterfeit tracing anti-theft tag based on the high-frequency NFC mechanism according to the present invention. Fig. 4 shows that when the anti-counterfeiting traceability anti-theft tag 10 based on the high-frequency NFC mechanism is attached to the article P for use, the article P is not checked out and the second coil 32 as the EAS coil is not destroyed or demagnetized, the status code is 0 (default value).
Fig. 5 shows that when the second coil 32 serving as the EAS coil is broken and becomes an open loop, and the IO interface 43 cannot be electrically connected to the ground interface 44 through the second coil 32, the NFC chip 40 detects that the IO interface 43 is floating, and the NFC chip 40 rewrites the state code to 1.
Fig. 6 shows that the NFC reader 50 sends a command to the NFC chip 40 to open the second coil 32 (i.e., the EAS coil) to become an open loop while the article P is checked out, and the NFC chip 40 rewrites the status code to 1. In other words, the NFC reader/writer 50 sends an instruction to the NFC chip 40 to rewrite the status code to 1, and then the status code cannot be changed any more, and the status code is still 1 even after being copied, so that the NFC chip 40 has a function of preventing recovery and copying. Therefore, if the anti-counterfeiting traceable anti-theft tag 10 based on the high-frequency NFC mechanism is copied or recycled, the manufacturer or the consumer can know whether the goods have problems by scanning and reading the status code, wherein the status code 1 indicates that the goods have been paid out or the second coil 32 is damaged.
The invention combines the NFC label and the EAS technology to realize the functions of anti-counterfeiting traceability, anti-tearing and anti-theft; meanwhile, when the anti-counterfeiting tracing anti-theft label 10 is pasted on a commodity after leaving a factory, the anti-counterfeiting tracing anti-theft label simultaneously has an EAS function, and a market or a merchant does not need to spend time to paste the EAS label, so that the cost is saved.
The above-described embodiments and/or implementations are only for illustrating the preferred embodiments and/or implementations of the present technology, and are not intended to limit the implementations of the present technology in any way, and those skilled in the art may make modifications or changes to other equivalent embodiments without departing from the scope of the technical means disclosed in the present disclosure, but should be construed as the technology or implementations substantially the same as the present technology.
