Description

Double-frequency RFID (radio frequency identification) washing label combining NFC (near field communication) and UHF (ultra high frequency)

Technical Field

The utility model belongs to the field that radio frequency identification technology and textile technology combined together specifically is a dual-frenquency RFID washing mark label that NFC and UHF combined together.

Background

An RFID (Radio Frequency Identification) electronic tag is a non-contact automatic Identification technology and is widely applied to the fields of logistics management, retail management, automatic production, identity Identification, anti-counterfeiting and anti-theft, and the like; the label of the water-washing label can be washed without fading, is mainly applied to industries such as clothes, home textiles and the like, and the specific use method is to print clothes parameters and cautions on the label. In recent years, an RFID label combining an RFID electronic tag and a washing label is gradually created in the clothing industry, and the RFID label is mainly characterized in that the RFID label has a radio frequency identification function on the basis of the washing label.

The common RFID electronic tags can be divided into three types, namely low frequency, high frequency and ultrahigh frequency according to the working frequency range, wherein the low frequency RFID electronic tags are not mainly applied to RFID washing labels due to the excessively short identification distance. Based on this, generally there are two kinds of high frequency RFID water washed mark labels and hyperfrequency RFID water washed mark label on the market, and clothing enterprise or manufacturer generally use the respective function of two kinds of labels respectively. Particularly, the high-frequency RFID label has an NFC (near field communication) function, and can read information of products, so that the high-frequency RFID label is mostly applied to anti-counterfeiting of clothes, for example, the NFC label is scanned by a mobile phone, and the authenticity information of commodities appears; the ultrahigh frequency RFID label has a large identification distance, can be used for realizing logistics management tracing and product theft prevention of clothing products, for example, when the clothing is maliciously carried out of a store, a store induction device can identify UHF label signals on the clothing and send an alarm.

However, in the practical operation of the garment industry management and sales lines, the following problems are mostly faced: the contradiction exists between logistics storage granulation management and batch quick recognition, products are easy to be stolen, and fake and shoddy products are easy to appear; therefore, the industry needs both logistics management traceability and product anti-theft, and product anti-counterfeiting. Therefore, on the premise that one RFID washable label cannot give consideration to the functions of a high-frequency label and an ultrahigh-frequency label, clothing enterprises or manufacturers can only give up one of the functions or set two labels on products. Wherein, set up two labels on the product and can let material cost greatly increased undoubtedly to the subsides mark process of label is complicated, also can lead to manufacturing cost to increase, does not have data association between two other independent labels, can make application scope receive certain restriction.

In conclusion, when the RFID water washing label is applied to the clothing industry, how to realize the internal management and the sales process of the industry simultaneously by optimizing the structure of the RFID water washing label, the logistics management tracing, the product theft prevention and the product anti-counterfeiting requirements are worthy of attention and research at present.

Therefore, the dual-frequency RFID chip can coordinate the mutual work of different antennas on two frequency bands, and the two frequency bands share the power supply, the central control logic circuit and the memory of the chip, so that the power supply conflict or the conflict of reading and writing the memory when the two frequency bands work simultaneously is avoided.

Further, washing mark label body includes that the washing at both ends marks the surface material layer, and the washing at both ends marks and is equipped with two-layer glue film between the surface material layer, encapsulates substrate layer and dual-frenquency RFID inlay between the two-layer glue film. Specifically, the front surface and the back surface of the label are both washing label surface material layers which are used for directly contacting with skin, are nontoxic and harmless and are washing-resistant; the glue film mainly plays the effect of accepting and encapsulating, can with substrate layer and dual-frenquency RFID inlay encapsulation in the washing mark surface material layer at both ends to make each layer zonulae occludens, form washing mark label body.

Furthermore, the NFC antenna is in series impedance matching with a radio frequency port of the dual-frequency RFID chip; and the UHF antenna is in conjugate matching with a radio frequency port of the dual-frequency RFID chip.

Furthermore, the washing label surface material layer is made of ribbon or nylon or washing cloth. The wash mark surface material layer uses flexible material can make the toughness and the texture of wash mark moderate to make the wash mark label of using on the clothing more skin-friendly.

Further, the substrate layer is made of PET or coated paper.

Furthermore, the glue layer is hot melt glue or self-contained glue.

The utility model discloses the beneficial effect who realizes is:

through the dual-frenquency RFID inlay that encapsulates NFC and UHF combined together in washing mark label body for the washing mark label of making has the characteristic of washing mark and compromise two kinds of electronic tags's of high frequency and hyperfrequency function. Compared with the existing RFID label of the water-washing label which can only realize the NFC or UHF function, the label can integrate the logistics management tracing and product anti-theft functions and the product anti-counterfeiting function into a whole, thereby greatly saving the manufacturing cost and effectively improving the production and management efficiency.
