Here, the substrate layer 140a may serve as a bottom layer of the antenna 122 and the rfid chip 124 of the electronic tag device 120, that is, the substrate layer 140a may be used to support the electronic tag device 120. The material of the base layer 140a is, for example, polypropylene (PP), Polyethylene (PE), polyester fiber (PET), Polyimide (PI), Propylene Carbonate (PC), polyvinyl chloride (PVC), Polystyrene (PS), or the like.

In addition, the rfid module 100a of the present embodiment further includes a first passivation layer 150 and a second passivation layer 160. The first protection layer 150 is disposed on the first surface 112 of the glass fiber board 110, wherein the electronic label device 120 is located between the first protection layer 150 and the glass fiber board 110. The second protective layer 160 is disposed on the second surface 114 of the glass fiber plate 110, wherein the foam material layer 130 is located between the second protective layer 160 and the glass fiber plate 110. The thickness T3 of the first passivation layer 150 ranges from 0.1 mm to 2 mm, and the thickness T4 of the second passivation layer 160 ranges from 0.1 mm to 2 mm. Here, the first protective layer 150 and the second protective layer 160 are provided to cover the base material layer 140a, the electronic tag device 120, the glass fiber plate 110, and the foam material layer 130, and to protect the base material layer 140a, the electronic tag device 120, the glass fiber plate 110, and the foam material layer 130. In addition, the first passivation layer 150 and the second passivation layer 160 can also be worn.

Preferably, the first protection layer 150 and the second protection layer 160 have waterproof and dustproof functions, wherein the first protection layer 150 and the second protection layer 160 are made of a material such as silicone, rubber, polyvinyl chloride (PVC), polypropylene (PP), Polyethylene (PE), polyester fiber (PET), propylene-butadiene-styrene (ABS), ethylene/vinyl acetate copolymer (EVA), Polystyrene (PS), or the like. In some embodiments, the surfaces of the first protective layer 150 and the second protective layer 160 can also be laser or printed with information or patterns to display related information or to enhance the appearance.

It should be noted that, in the embodiment not shown, the first protection layer 150, the substrate layer 140a, the electronic label device 120, the glass fiber board 110, the foam material layer 130 and the second protection layer 160 can also be bonded through an adhesive layer with adhesiveness between the layers, which still belongs to the protection scope of the present invention.

In the manufacturing process, the substrate layer 140a, the electronic label device 120, the glass fiber plate 110 and the foam material layer 130 can be completely covered by the first protective layer 150 and the second protective layer 160 through injection molding, extrusion, mold pressing or bonding, so as to achieve the waterproof and dustproof effects. At this time, the function of the glass fiber plate 110 not only can increase the reading distance and range of the rfid module 100a, but also can prevent the electronic tag device 120 from shifting during the injection molding process.

In application, the rfid module 100a may be made into a wristband to be worn on the wrist, i.e. the rfid module 100a may be made into a wearable module, and the materials of the first protective layer 150 and the second protective layer 160 are preferably silica gel materials. Because the silica gel material has the characteristics of no toxicity, no cracking, long service life, no skin irritation and the like, and has the advantages of water resistance, moisture resistance, shock resistance and high temperature resistance. In addition to being worn on the wrist as a wristband, the rfid module 100a may also be incorporated into any wearable device such as an identification card, an arm ring, a safety helmet, a work-site hat, a protective clothing, or a warning vest. In short, the rfid module 100a can be manufactured into wearing device products directly by injection molding, extrusion molding, mold pressing, etc. according to different usage situations, or can be attached to clothes by adhesive layers of different viscosities to form other types of wearing devices, all of which belong to the protection scope of the present invention.

Furthermore, if the rfid module 100a is applied to a hospital, the patient can be immediately controlled to trace and related medical record information, so as to prevent the patient from mistakenly running or leaving a predetermined location or immediately obtaining related disease treatment. If the rfid module 100a is applied to daily life, it can prevent the elderly or children from losing the intelligence, and can immediately know the track or facilitate the police to identify and further assist. In many work safety accidents, the gold rescue time is missed because the staff with accidents cannot be found at present. Therefore, if the rfid module 100a is applied to a factory, the injured person can be found immediately, and the person can be effectively controlled to move to a dangerous area. If the RFID module 100a is applied in a company, it can be used as an identification certificate to control the attendance status and track of employees, so as to avoid the information stealing by mistakenly running through an important machine room.

Please refer to the reading distance test result of the rfid module in table one below, wherein the test sample is the rfid module 100a of fig. 1 including the glass fiber plate 110 and the foam layer 130 of the present embodiment, and the comparison group in the test sample is the rfid module without the glass fiber plate but including the foam layer. The test conditions are the same, the same reader and the same test environment are adopted, and each test sample is attached to the same human wrist during each test.

Watch 1

As can be seen from the test results, the average reading distance of the control group is only about 108 cm because the control group does not contain the glass fiber plate; in contrast, the rfid module 100a of the present embodiment includes the glass fiber plate 110, so that the average reading distance is 232 cm, which can increase the reading range by more than 1 meter (100 cm). In other words, the rfid module 100a including the glass fiber plate 110 can still be read accurately even at a long distance.

In short, in the design of the rfid module 100a of the present embodiment, the reading distance and range of the rfid module 100a are increased by the arrangement of the glass fiber plate 110, and the medium interference (such as human body) is isolated by the arrangement of the foam layer 130. Therefore, the rfid module 100a of the present embodiment can stably read data from a long distance, and can quickly achieve the group reading function and the anti-interference function. In addition, the rfid module 100a of the present embodiment further has the first passivation layer 150 and the second passivation layer 160, so as to have waterproof and dustproof functions.
