Description

Water-washing invalid RFID radio frequency tag and using method thereof

Technical field

The present invention relates to the field of radio frequency identification, and in particular to a water-washed RFID radio frequency tag and a method of using the same.

Background technique

RFID is a wireless communication technology that can identify specific targets and read and write related data through radio signals without identifying mechanical or optical contact between the system and a specific target. The radio signal is modulated by the electromagnetic field of the radio frequency. It is transmitted from the label attached to the item to automatically identify and track the item. Some labels can receive energy from the electromagnetic field emitted by the identifier when identifying, and do not need the battery; also the label itself has power and can Actively emits radio waves. The tag contains electronically stored information that can be identified within a few meters. Unlike a bar code, the RF tag does not need to be within the line of sight of the recognizer or it can be embedded within the object being tracked.

Radio frequency identification electronic tag technology is widely used, typical applications: animal wafer, access control, air package identification, document tracking management, parcel tracking identification, animal husbandry, logistics management, mobile commerce, long-distance running anti-counterfeiting, sports timing, ticket management, automotive Chip anti-theft device, parking lot control, production line automation, material management and other fields.

At the same time, with the increasing popularity of radio frequency tags, radio frequency tags have also been widely used in people's clothing products: traditional RFID tags (tags) or in the form of tags, consumers cut off after purchase (outbound cut), consumers When the product is not satisfied with the return of the product, it is impossible to identify whether it is the original goods, or it is dissolved in the form of a label or a garment lining. This form, although identifying the manufacturer, is The “monitoring” consumer experience, while the clothing brand manufacturers have washed the unreturnable interest needs.

Summary of the invention

The present invention is directed to the disadvantages of the prior art that the RFID tag cannot determine whether the product has been washed by water, and provides a water-washed RFID radio frequency tag and a method of using the same.

In order to solve the above technical problems, the present invention has been solved by the following technical solutions.

A water-washed RFID radio frequency tag, including an RFID chip and an antenna, a water-soluble layer, and a waterproof layer. The RFID chip and the antenna are disposed between the two water-soluble layers, and the outer sides of the two water-soluble layers are covered with the waterproof layer.

Preferably, the water-soluble layer comprises a hydrosol and a water-soluble paper, the hydrosol covers the outer side of the RFID chip and the antenna, and the water-soluble paper is disposed between the waterproof layer and the hydrosol.

Preferably, the water repellent layer is a PP film or a PET film.

A method for using a flushed RFID radio frequency tag includes the following steps:

Paste the RFID radio frequency tag on the item for sale;

Remove the waterproof layer of the outer layer of the RFID radio frequency tag when selling the product;

If the water is detected, the radio frequency validity of the RFID radio frequency tag is judged, and the result is valid. It can be judged that the product has not been subjected to the water treatment, and the result is invalid, and the product can be judged to be in contact with the water treatment.

Preferably, a radio frequency reader is used in the detection process for detecting the radio frequency validity of the RFID radio frequency tag on the commodity.

Preferably, the item for sale is a garment, and the result is effective. It can be judged that the product has not been subjected to water treatment, and the product can be exchanged. The result is invalid, and the product can be judged to be in contact with water treatment, and the replacement processing cannot be performed.

The invention adopts the above technical solutions and has remarkable technical effects: the invention combines the water-soluble layer with the radio frequency antenna and the chip, so that the RFID radio frequency label attached to the clothing product is washed and the structure is more easily destroyed, and the radio frequency is broken. After the signal disappears, the purpose of marking the washed clothing product is achieved. After the consumer purchases the clothing product, the merchant performs a return inspection for the consumer who needs to return the goods, which simplifies the process of returning the goods and saves time. During the merchant inspection process, the RFID radio frequency tag on the clothing product is inspected by the RF reader, and it can be judged whether the garment is washed or not, and the result is effectively fed back.

detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

As shown in FIG. 1, a water-washed RFID radio frequency tag includes an RFID chip and an antenna 1, a water-soluble layer and a waterproof layer 3, The RFID chip and the antenna 1 are disposed between the two water-soluble layers, and the outer sides of the two water-soluble layers are covered with the waterproof layer 3. The water-soluble layer includes a hydrosol 4 and a water-soluble paper 2, the hydrosol 4 covers the outer side of the RFID chip and the antenna 1, and the water-soluble paper 2 is disposed between the waterproof layer 3 and the hydrosol 4. The waterproof layer 3 is a PP film or a PET film.

Paste the RFID radio frequency tag on the item for sale;

When the product is sold, the waterproof layer 3 of the outer layer of the RFID radio frequency tag is removed;

A radio frequency reader is used in the detection process to detect the radio frequency validity of the RFID radio frequency tag on the commodity.

The goods for sale are clothing, and the result is valid. It can be judged that the goods have not been treated with water, and the goods can be exchanged. The result is invalid. It can be judged that the goods are in contact with water and cannot be exchanged.

In the present invention, the RFID chip and the antenna 1 are stripped of the carrier of the layer, and are covered by the water-soluble layer on the outside of the RFID chip and the antenna 1. In use, the outer layer has a protective waterproof layer 3, and when the consumer is washed or placed in a humid environment, the water-soluble layer is dissolved, and the internal RFID chip and antenna 1 structure are more easily destroyed.
