Description
Technical field
The present invention relates to REID（Radio Frequency Identification, abridge RFID）, especially
It is a kind of RFID label tag and its manufacture method to be related to.
Background technology
REID（Radio Frequency Identification, abridge RFID）It is one using radio frequency to believe
Number realize contactless information transmission by Space Coupling (alternating magnetic field or electromagnetic field) and pass through transmitted information and reach identification
The technology of purpose.With conventional identification techniques（Quick Response Code, bar code etc.）Compare, RFID technique, which has, indicates unique, information capacity
Greatly, efficient and convenient, multi-tag is read to read, the characteristics of data encryption can be carried out.Article is widely used to by years development
The field such as tracking, aviation luggage sorting, factory's assembling line, automobile burglar, electronic bill, the care of animal, commodity counterfeit prevention.
RFID can be divided into low frequency (30 ~ 300kHz), intermediate frequency (300kHz ~ 3MHz), high frequency because carrier wave frequency range is different
(3 ~ 30MHz) and hyperfrequency (300MHz ~ 3GHz).Wherein, the EFFECTIVE RANGE of hyperfrequency (UHF) frequency range is maximum, Ke Yida
To 8 ~ 20m, retail stores management and traffic and transport field can be widely applied to.The agreement of ultrahigh-frequency radio-frequency identification system has much at present
Kind, it can be largely classified into two big agreement makers：First, ISO (International Organization for standardization);Second, EPC Global.ISO is organized
Radio Frequency Identity Protocols ISO18000-6 has been formulated currently for uhf band, and EPC Global tissues have then been formulated and have been directed to product
