Problems solved by technology
When mounted on the surface of all metal packaged products (such as: cigarettes wrapped in aluminum foil, commonly known as tinfoil), the metal package behind the RFID will produce eddy current or reflection effects on the electromagnetic field emitted by the reader, making it difficult for RFID Normal work, even basic read and write operations, especially for passive RFID electronic tags widely used in anti-counterfeiting traceability
[0003] At present, the conventional solution is to use a special RFID electronic tag with a ferrite anti-jamming barrier on the back, but it is difficult to use it on many commodities because of its cost, thickness and concerns about food safety.
[0004] Therefore, although RFID electronic tag anti-counterfeiting technology has been widely used in the anti-counterfeiting of alcohol, clothing (glass or plastic packaging), etc., due to the existence of the aforementioned technical gap, this technology still cannot be applied to cigarettes on a large scale. anti-counterfeiting top

Embodiment Construction
[0023] The specific implementation method of the present invention will be further described below in conjunction with the accompanying drawings and examples, but it should not be understood that the scope of the present invention is limited to the following examples. Without departing from the above method of the present invention, various replacements and changes can be made according to common technical knowledge and customary means in this field, and all should be included in the protection scope of the present invention.
[0024] Such as figure 1 As shown, the existing cigarette boxes are generally packaged with carton materials, and the outer shell can be divided into soft packaging and hard packaging. "Aluminum foil paper"), in the space wrapped by aluminum foil paper, cylindrical tobacco is neatly arranged.
[0025] Embodiments of the present invention can be as Figure 2-9 like that.
[0026] That is, a cigarette package attached with an RFID electronic tag still i...

The invention discloses a cigarette packaging body adhered with a radio frequency identification (RFID) electronic tag. Local processing is conducted on a metal packaging layer at the back of an RFID pasting and installing position, and the eddy current effect and the regular reflection effect of the metal layer at the back of the RFID electronic tag is destroyed, so that electromagnetic background interference of the metal layer at the back of the RFID electronic tag can not cover the signals of an RFID reader-writer and the RFID electronic tag. The RFID electronic tag and the reader-writer can work reliably at a certain distance and be applied to anti-counterfeiting of cigarettes wrapped in metal.
Description
technical field [0001] The invention relates to the technical fields of the Internet of Things and commodity anti-counterfeiting. Background technique [0002] RFID electronic tags are more and more widely used in the fields of commodity circulation and anti-counterfeiting traceability, but because of the working principle of RFID itself, radio frequency electromagnetic fields are used between RFID and its readers as the carrier of energy and information transmission. When mounted on the surface of all metal packaged products (such as: cigarettes wrapped in aluminum foil, commonly known as tinfoil), the metal package behind the RFID will produce eddy current or reflection effects on the electromagnetic field emitted by the reader, making it difficult for RFID Normal work, even basic read and write operations, especially for passive RFID electronic tags that are widely used in anti-counterfeiting and traceability. [0003] At present, the conventional solution is to use a sp...
