One of the features of passive RFID tags is lightweight and convenient. Gewone RFID-etikette is slegs 'n paar millimeter dik, maar in die algemeen, die breedte en hoogte van die etiket is 'n paar sentimeter. This is because of the antenna limitations of the tag. RFID chips are only one-tenth the size of a sesame, even if the bound cob is generally one or two millimeters square. Egter, passive RFID tags require relatively large antennas to meet the reading distance requirements of practical applications, such as a few centimeters of high-frequency tags and a few meters of UHF tags. This is actually very well understood. Net soos die outydse radio, when we are using it, ons moet die antenna gewoonlik verleng. Hoe langer die antenna, the stronger the signal and the more stable it is. RFID is the abbreviation of Radio Frequency Identification; the passive RFID tag receives power through the antenna, thereby activating the chip to achieve the operation and storage function, en die etiket self het nie 'n battery nie. Daarom, to make the tag small and to ensure the reading distance, jy moet 'n ophef op die antenne maak.
Streng gesproke, the smallest RFID tags on the market is mass-produced and put on the market by RAINRFID on August 31, 2017.
The size of the tags are 1.25×1.25×0.55mm. The tag can be applied to instruments such as medical instruments. It is skillfully inserted into the metal surface and the instrument itself is used as the carrier of the antenna. Afstandsvereistes. Hierdie etiket is baie geskik vir gebruik in presisie-instrumente, horlosies, jewelry and other items, speel teen-vervalsing, nommering, diefwering en so aan. Egter, as gevolg van die hoë prys, dit word nie wyd op die mark gebruik nie.
Oor die algemeen, die mark het toepassings verouder. Die kleinste merker wat in groot hoeveelhede gebruik word, is die RFID Microchip Tag. (Glasbuisdiagram) Hierdie merker kan groot word (), hierdie etiket behoort tot die dierebestuurmerker, amptelik gebruik. Vir katte en honde troeteldiere, visbestuur. Die etiket word met behulp van 'n spuit in die dier ingespuit. Die lewensduur en hoë stabiliteit van meer as 10 jare kan lewenslank vir klein diere gebruik word. www.rfidhy.com/rfid-products/rfid-glass-tube-tag/
Because its price is only a few tens of cents, en die stabiliteit daarvan is goed, it is widely used in the pet industry and wildlife conservation projects in the breeding industry.
