The technical solution of the utility model is that: a license plate with a built-in RFID chip is characterized by comprising a membrane bottom plate, a composite layer and an RFID chip;

the diaphragm bottom plate is an integrally formed plastic bottom shell;

the RFID chip is arranged in the membrane bottom plate;

the composite layer comprises a glue layer, a reflecting layer, a UV optical layer, a printing layer and a diaphragm layer which are sequentially adhered, and the composite layer is arranged on the diaphragm bottom plate.

Preferably, the method comprises the following steps: the RFID chip is provided with a positioning hole in a penetrating mode, a containing cavity is arranged in the diaphragm bottom plate, and a positioning column matched with the positioning hole is arranged in the containing cavity.

Preferably, the method comprises the following steps: the glue layer is IMD glue layer.

Preferably, the method comprises the following steps: the reflecting layer is either an electroplated layer or a nano silver paste layer.

Preferably, the method comprises the following steps: the UV optical layer comprises an optical micro prism layer and a holographic anti-counterfeiting layer.

Preferably, the method comprises the following steps: the upper side of the license plate is also provided with a mounting hole in a penetrating way, and the mounting hole penetrates through the membrane bottom plate and the composite layer.

Compared with the prior art, the beneficial effects of the utility model are that:

the membrane bottom plate is integrally formed after twice injection molding, the plastic bottom plate with the containing cavity is formed by first injection molding, the positioning columns in the containing cavity are matched with the positioning holes on two sides of the RFID chip to form suspended positioning, and then the second injection molding is carried out, the RFID chip is completely wrapped in the integrally formed membrane bottom plate;

the two times of injection molding of the diaphragm bottom plate are both made of the same material, the license plate formed by injection molding does not have an obvious boundary line, and the adhesion force between the two sides of injection molding is stable;

the license plate pattern adopts a composite layer, and the optical film is used as the license plate, so that the reflective effect can be achieved, and meanwhile, the license plate pattern or image displayed on the optical film can have the anti-counterfeiting function which can be directly identified by naked eyes, the counterfeiting cost is increased, and the risk of counterfeit the license plate is reduced;

the utility model discloses a UV optical layer embeds has optics microprism and holographic anti-fake layer, and is more excellent than little glass pearl reflection of light technique, and the reflection of light rate is high, and reflection of light angle, distance direction height are controllable, and the IMD glue that cooperates the glue layer to use simultaneously makes the composite bed can be through the mode integrated into one piece of moulding plastics on the diaphragm bottom plate.
