Description

Enhanced anti-counterfeiting RFID (radio frequency identification) label

Technical Field

The utility model relates to an information technology field especially relates to an strengthen anti-fake type RFID label with anti-fake field.

Background

At present, the anti-counterfeiting situation of the commodities is more severe, and the requirements and the use amount of the commodities on the market for anti-counterfeiting are gradually increased.

The adoption of RFID anti-counterfeiting is a preferred scheme which takes counterfeiting difficulty and cost performance into consideration. The RFID anti-counterfeiting uses a semiconductor chip, and the chip has an encrypted storage area besides a global unique code. The reason that the global unique code cannot be imitated or copied is that the manufacturing process requirements of the chip determine the number of fingers of a semiconductor manufacturer which can produce the chip in the world, and once the situation occurs, the semiconductor manufacturer is easy to find out the production source, and the manufacturer cannot go at risk for the small profit of the fly head and the moral and commercial compensation collar after the fact is found.

The encryption mechanism of the RFID chip is difficult to crack, the energy required by a cracker is different from the product value by several orders of magnitude, but considering that the number of commodities is huge, some lawless persons participate in the process. However, in recent years, chip anti-counterfeiting is realized by arranging a unique key on each chip, so that a cracker can spend huge energy on cracking each RFID label, and even if part of the RFID labels are cracked, the cracker can not forge in batches, so that the counterfeiting cost is too high, and on the other hand, the anti-counterfeiting chip can effectively protect the positive products.

And the anti-counterfeiting system also utilizes a network authentication mode, and the RFID label reading equipment actively uploads the ID and the encrypted information of the RFID chip, so that the authenticity of the RFID label is verified from a background, and a counterfeiter is difficult to add.

However, a counterfeiter starts to perform counterfeiting by means of packaging recycling, RFID tag recycling, and the like, because only the verification frequency can be identified in the anti-counterfeiting system, but the verification frequency is not a standard for determining whether the RFID tag is reused, and because the RFID tag is verified by the RFID tag without destroying the RFID tag, it is impossible to determine whether the RFID tag is a genuine product. Therefore, at present, the consumer can only judge the authenticity of the goods according to the data of the RFID label which is identified for several times.

At present, some RFID labels also use random codes on the surface to implement a double verification mechanism, but a counterfeiter can copy the random codes under the condition of not damaging the RFID labels, and an anti-counterfeiting system cannot identify the authenticity.

Because the RFID anti-counterfeiting label has the non-replicability except the chip, other materials and printing can be easily imitated, some counterfeiters can even take the chip off the package to re-manufacture the RFID antenna and the whole set of anti-counterfeiting label, and the aim of falsely and truly is achieved.

Yet another key problem is that counterfeiters typically recycle genuine packages at a high price, virtually forcing consumers to sell complete packages to counterfeiters. The consumer verifies the product authenticity by self to ensure that the counterfeit goods are not consumed, the product authenticity can be verified under the condition of not damaging the RFID chip of the existing anti-counterfeiting label, at present, some composite anti-counterfeiting verification modes adopting random codes are usually special printing labels, a counterfeiter only needs to imitate the special printing labels to be pasted on the packages of the received genuine goods, and the imitated goods can pass the genuine goods verification. Therefore, the existing RFID anti-counterfeiting label cannot realize good anti-counterfeiting effect.

Disclosure of Invention

The utility model aims to solve the defects of the prior art, and designs a reinforced anti-counterfeiting RFID label, which leads the consumer to actively damage the RFID label in the verification process through the structural design, in particular to the connection part of a chip and an antenna, thereby solving the problem that the RFID label is repeatedly utilized,

the utility model discloses a realize like this: the utility model provides an enhancement mode anti-fake RFID label, includes antenna substrate and locates the positive RFID antenna of antenna substrate, the RFID chip, the non-setting adhesive layer and the label printing surface course of locating the antenna pad department of RFID antenna from inside to outside order, its characterized in that: the antenna substrate back be equipped with through spouting the random sign indicating number that the seal equipment spouted and seal the formation and spout the seal layer, random sign indicating number spout the seal layer and contain at least a set of random sign indicating number. The random code spraying layer is sprayed and printed on the back surface of the antenna base material through UV code spraying equipment, the arrangement position of the random code spraying layer corresponds to the arrangement position of the RFID chip and is partially or completely overlapped, so that the RFID chip and the antenna bonding pad shield partial or all random codes on the random code spraying layer. The antenna base material of the RFID tag is a transparent antenna base material. The RFID label is adhered to the surface of the commodity through the adhesive sticker layer arranged on the back surface of the RFID label.

The utility model has the advantages that: because the RFID chip of the RFID label is generally only 0.5 multiplied by 0.5mm in size and almost has the size of one sand, when a consumer needs to read the random code to verify a commodity, the conductive adhesive between the RFID chip and the RFID antenna must be broken to see the random code, and because the common consumer does the breaking action more randomly and roughly, the RFID chip can fall off after the conductive adhesive is broken, so that the RFID antenna cannot be found, and most of the time can be damaged. Even if the counterfeiter recovers the outer package, because the RFID label does not have the RFID chip, the consumer who takes the counterfeit product cannot carry out commodity verification through the anti-counterfeiting platform. And simultaneously, because the utility model discloses a random sign indicating number spouts seal layer to cover and pastes in the commodity surface after having the not dry glue film, and random sign indicating number spouts seal layer adhesive force weaker, and the not dry glue film has viscidity again, so even make on the fake person thinks that the RFID label on will the genuine article through whole transfer means is harmless to be shifted to the imitative article, also hardly realize basically, has stopped the condition of retrieving the fake product with regard to fundamentally like this.
