RFID tag qhov sib txawv

Xov tooj cua zaus identification (RFID) tags lossis transponders yog cov khoom siv me me uas siv cov xov tooj cua tsis muaj zog kom tau txais, khaws thiab xa cov ntaub ntawv mus rau cov neeg nyeem nyob ze. RFID tag muaj cov khoom tseem ceeb hauv qab no: microchip lossis integrated circuit (IC), tus kav hlau txais xov, thiab cov khoom siv tiv thaiv substrate uas tuav tag nrho cov khoom ua ke.

Muaj peb hom RFID cim npe: passive, nquag, semi-passive lossis roj teeb pab passive (BAP). Passive RFID cim npe tsis muaj lub zog sab hauv, tab sis yog siv los ntawm hluav taws xob hluav taws xob xa tawm los ntawm RFID nyeem ntawv. Active RFID tags nqa lawv tus kheej transmitter thiab lub zog ntawm lub cim npe. Semi-passive lossis roj teeb pab passive (BAP) cov cim npe suav nrog lub zog hluav taws xob sib txuas rau hauv kev teeb tsa passive tag. Tsis tas li ntawd, RFID tags ua haujlwm nyob rau hauv peb qhov ntau zaus: Ultra High Frequency (UHF), High Frequency (HF) thiab Tsawg zaus (LF).

RFID cov cim npe tuaj yeem txuas rau ntau qhov chaw thiab dav dav hauv ntau qhov ntau thiab tsawg thiab tsim. RFID cov cim npe kuj tuaj yeem muaj ntau hom ntawv, suav nrog tab sis tsis txwv rau cov ntaub ntub dej, cov ntaub ntub dej qhuav, cov ntawv cim npe, cov hlua tes, cov cim tawv tawv, daim npav, cov ntawv nplaum, thiab cov hlua tes. Cov cim npe RFID muaj nyob rau ntau qhov chaw sib txawv thiab kev siv,
