The present invention relates to a belt type anti-counterfeit label and a radio frequency identification system using the same, and more particularly to a belt type anti-counterfeit label for increasing the anti-counterfeiting and anti-theft mechanism of the commodity.

In recent years, radio frequency identification (RFID) technology has gradually replaced the existing bar code technology due to its advantages of non-contact identification and data security, and is widely used in various fields, such as inventory. List management, automatic vehicle identification, store burglary and logistics control.

In general, the transmission frequency of the RFID system has three forms: low frequency, high frequency and ultra high frequency. Therefore, designers can select different types of transmission frequency RFID systems for the needs of specific issues. In addition, the RFID technology is mainly composed of a reader and an RFID tag. Among them, the antenna is arranged in the reader and the RFID tag to facilitate the radio frequency transmission, and the antenna design can be adjusted and improved according to specific requirements. Furthermore, the RFID tag can utilize its internal identification chip for identification purposes.

However, it is worth noting that most of the existing RFID systems use the method of attaching to fix the RFID tag on the item to be identified. In this case, the thief can easily remove the RFID tag from the item and easily steal the item or replace the item with a defective item. In other words, the existing RFID system has extremely weak anti-counterfeiting and anti-theft functions, so that people with a heart can take advantage of it.

The invention provides a belt type anti-counterfeit label, which can be applied to tracking, identification and monitoring of goods, and is used for increasing anti-counterfeiting and anti-theft mechanism of goods.

The invention provides a radio frequency identification system, which utilizes a belt type anti-counterfeit label to achieve a perfect anti-counterfeiting and anti-theft mechanism.

The invention provides a strap type anti-counterfeit label, comprising a strap and an RFID tag. Wherein the strap includes a strap body having a first tooth structure and a buckle having a second tooth structure. In practical use, the belt body can be locked into the buckle by the engagement of the first tooth structure and the second tooth structure, and the belt can form an annular opening to bind a sample to be tested. Furthermore, the RFID tag is used to receive or transmit an RF signal through an antenna. In addition, the antenna is disposed within the interlayer of the strap body and extends between the ends of the strap body. As a result, when the belt body is subjected to the interception of the external force, the antenna will not operate normally.

In an embodiment of the invention, the strap body has a first end, a second end, and a plurality of side surfaces. Wherein the first end of the strap body is coupled to the buckle. The second end of the strap body is used to lock into the buckle. Further, one of the side surfaces of the band body has a first tooth structure.

In an embodiment of the invention, the buckle has a hole and a hook portion. Among them, the hole penetrates the buckle. The hook portion has a second tooth structure exposed in the hole.

In an embodiment of the invention, the radio frequency identification tag comprises an identification chip. The identification wafer is disposed in the interlayer of the strap body and electrically connected to the antenna. In practice, the identification chip is used to process the signal received by the antenna, and the unique identification code stored therein is transmitted through the antenna according to the processing result.

The invention further provides a strap type anti-counterfeit label, comprising a strap, a loop shorting device and an RFID tag. Wherein the strap includes a strap body having a first tooth structure and a buckle having a second tooth structure. Here, the strap body can be locked into the buckle by the engagement of the first tooth structure and the second tooth structure, and the strap is formed into an annular opening to bind an object to be tested.

On the other hand, the loop shorting device is locked to the buckle. The RFID tag is used to receive or transmit an RF signal through an antenna. The antenna includes a body portion and an extension portion. The body portion is disposed within the interlayer of the strap body and extends between the ends of the strap body. The extension is disposed in the interlayer of the strap body and the buckle, and is electrically connected to the loop shorting device.

In the overall operation, when the strap body is inserted into the hole of the buckle, the circuit short-circuiting device is damaged, and the body portion and the extension portion of the antenna form an energizing circuit to cause the antenna to operate normally. In addition, and when the belt body is subjected to the interception of the external force, the antenna will not operate normally.

From another point of view, the present invention provides a radio frequency identification system comprising a plurality of said strap type anti-counterfeit tags and a reader. The device is configured to read the RF signals transmitted by the bundle type anti-counterfeit labels, and identify the objects to be tested bundled by the bundle type anti-counterfeit labels according to the reading result. It is worth mentioning that when the reader cannot receive the radio frequency signals transmitted by the respective belt-type anti-counterfeit labels, it will determine that the object to be tested bundled by the belt-type anti-counterfeit labels has been stolen or Has been replaced.

In summary, the present invention utilizes a mechanism in which the strap can only be fastened and cannot be loosened, and an antenna that is extended at both ends of the strap body, so that removal of the strap type anti-counterfeit label must destroy the strap and the antenna. structure. Therefore, compared with the prior art, the strap type anti-counterfeit label of the present invention can increase the anti-counterfeiting and anti-theft mechanism of the commodity, thereby causing the radio frequency identification system to be more automated and digitally controlled in anti-counterfeiting and anti-theft of the commodity. And wisdom.

Furthermore, the strap type anti-counterfeit label of the present invention has two implementation schemes: (1) the above-mentioned belt type anti-counterfeit label design to facilitate mass production of the belt type anti-counterfeit label; and (2) to strengthen the belt type anti-counterfeiting type. The anti-counterfeiting anti-theft function of the label, another design scheme is to set a loop short circuit device at the buckle. When the second end of the strap body passes through the hole of the buckle, the loop shorting device will be broken to form a energized loop. The purpose of this mechanism is to make the strap type anti-counterfeit label not function properly before binding the object to be tested. To put it simply, the difference between the two belt-type anti-counterfeit labels is that the belt-type anti-counterfeit labels need to be bundled with the items to function properly. As far as the application level is concerned, which solution to choose will depend on its application content.

The above described features and advantages of the present invention will be more apparent from the following description.

In the following description, in order to present the consistency of the description of the present invention, in the different embodiments, the same element symbols and names are used for the same or similar elements.

FIG. 1A is a schematic structural view of a strap type anti-counterfeit label according to an embodiment of the invention. Referring to FIG. 1A, the strap type anti-counterfeit label 100 includes a strap 110 and an RFID tag 120. The strap 110 includes a buckle 111 and a strap body 112. The RFID tag 120 includes an identification chip 121 and an antenna 122.

With continued reference to FIG. 1A, the strap body 112 has a first end 131, a second end 132, and a plurality of side surfaces. In the present embodiment, the first end 131 of the strap body 112 is coupled to the buckle 111. One of the side surfaces of the belt body 112 has a first tooth structure 133. The surface of the second end 132 of the strap body 112 then assumes an arcuate profile. In addition, the material constituting the band body 112 may be plastic, rubber, silicone, synthetic material or polymer material. It should be noted that those skilled in the art can arbitrarily change the implementation of the belt body 112 as required by the design.

On the other hand, the buckle 111 has a hole 141 and a hook portion 142. In the present embodiment, the hole 141 penetrates the buckle 111. The hook portion 142 has a second tooth structure 143 exposed in the hole 141. The second tooth structure 143 of the buckle 111 and the first tooth structure 133 of the belt body 112 are in mesh with each other.

Thereby, as shown in FIG. 1B, the strap body 112 can be locked into the buckle 111 by the engagement of the first tooth structure 133 and the second tooth structure 143. At this point, the strap 100 will form an annular opening 150. Here, the size of the annular opening 150 becomes smaller as the strap body 112 is continuously locked into the buckle 111. As such, as shown in FIG. 2, the strap 110 will be permeable to the object to be tested 201 through the annular opening 150. In addition, since the annular opening 150 can bundle the object to be tested 201, the band 110 can be fixed to the object to be tested 201.

Referring to FIG. 1A, the identification wafer 121 and the antenna 122 are both disposed in the interlayer of the strap body 112. In addition, the antenna 122 extends between the ends 131 and 132 of the strap body 112. The identification wafer 121 is electrically connected to the antenna 122. In this embodiment, the RFID tag 110 receives or transmits an RF signal through the antenna 122. The identification chip 121 is configured to process the signal received by the antenna 122, and transmits an identification code stored therein through the antenna 122 according to the processing result. Thereby, the belt type anti-counterfeit label 100 can be applied to the tracking, identification and monitoring of goods, such as: aviation and freight transportation, inventory management, automatic vehicle identification, and logistics control.

In addition, as shown in FIG. 1B and FIG. 2, when the band 110 is fixed on the object to be tested 201, the antenna 122 disposed in the interlayer of the band body 112 also surrounds the object to be tested 201 at the same time. It should be noted that the strap 110 can only be tied tightly and cannot be loosened after being bundled with the object 201. Therefore, if the belt type security label 100 is to be removed from the object to be tested 201, it is necessary to simultaneously cut off the belt body 112 and the antenna 122. In other words, when the strap body 112 is subjected to the interception of the external force, the antenna 122 will also not operate normally.

In other words, when the stealer removes the strap type anti-counterfeit tag 100 from the object to be tested 201, the damaged antenna 122 will reflect that the object to be tested 201 has been stolen or has been replaced by a defective product. Further, the system to which the belt type anti-counterfeit label 100 is applied achieves the functions of anti-counterfeiting and anti-theft.

It should be noted that in this embodiment, the RFID tag 120 can be formed by a passive RFID tag or an active RFID tag. Wherein, when the RFID tag 120 is a passive RFID tag, the band type anti-counterfeit tag 100 has the advantages of miniaturization and low cost. In contrast, when the radio frequency identification tag 120 is an active radio frequency identification tag, the efficiency and reliability of the information transmitted by the band type anti-counterfeit tag 100 can be improved.

FIG. 3A is a schematic structural view of a strap type anti-counterfeit label according to another embodiment of the present invention.

The body portion 310a is disposed in the interlayer of the strap body 112 and extends between the two ends of the strap body 112. The extension portion 310b is disposed in the interlayer of the strap body 112 and the buckle 111, and is electrically connected to the loop shorting device 320.

It is worth noting that the operation of the antenna 310 depends on the loop shorting device 320 in overall operation. Here, as shown in FIG. 3B, when the second end 132 of the strap body 112 passes through the hole 141 of the buckle 111, the loop shorting device 320 will be broken. At this time, the main body portion 310a and the extending portion 310b will form an energizing circuit to cause the antenna 310 to operate normally. The purpose of this mechanism is to make the strap type anti-counterfeit label 300 not function properly before the object to be tested is unbundled.

On the other hand, similar to the embodiment of FIG. 1A, in order to remove the strap type anti-counterfeit tag 300 from the object to be tested, it is necessary to simultaneously cut the band body 112 and the body portion 310a of the antenna 310. In other words, when the strap body 112 is subjected to the interception of the external force, the antenna 310 will not operate normally, thereby achieving the functions of anti-counterfeiting and anti-theft. The other detailed working principles of the present embodiment are included in the above embodiments, and thus are not described herein.
