Nws kuj qhia tau hais tias Taiwan yog lub teb chaws uas tsim nyog rau RFID txoj kev txhim kho.

(2) Kev sib raug zoo ntawm RFID thiab luam ntawv

Tom qab tus txheej txheem teev, lub kauj ruam tom ntej yog li cas RFID yuav nrov. Vim hais tias tus nqi yeej ib txwm yog ib qho ntawm lub hauv paus tseem ceeb hindering cov chaw ntawm RFID, luam ntawv yog ceev dua thiab pheej yig dua li cov qauv tshuaj tiv thaiv. Yog li ntawd, nws yog qhov pheej yig thiab ua haujlwm kom luam tau cov kav hlau txais xov mus rau RFID los ntawm kev luam ntawv. Muaj qee cov chaw lag luam hauv RFID xav tias qhov kev luam ntawv yuav ua rau RFID tus kav hlau txais xov ntau tshaj 50,000-80,000 ib xuab moos. Ntsib qhov kev xav tau loj uas los nrog nws. Qhov loj tshaj plaws ntawm kev luam ntawv luam tawm yog tias - ntev npaum li cov mesh sib txawv ntawm cov template, cov ntaub ntawv ntau case number yuav siv los luam cov khoom yam khoom, uas txhais tau hais tias tus cwj pwm uas siv tau ua ntau ntau, thiab feem ntau Dab tsi yog yuav pab tau yog qhov no hu ua tus cwj pwm xaj. Nyob rau hauv cov ntaub ntawv luam tawm, yog tias luam tawm, cov xov tooj yuav luam tawm rau ntau hom ntawv sau, xws li polyester, PVC los sis ntawv txawm. Nyob hauv tus txheej txheem ntawm kev luam lub kav hlau txais xov, tsuav tus kav hlau txais xov yuav tsum tau luam tawm ntawm cov ntawv luam tawm raws li qhov tsim nyog, nws tsis yog qhov yuav tsum tau ua kom puas qhov teeb meem luam tawm nws tus kheej xws li cov txheej txheem ntawm cov txheej txheem, uas tsis tsuas yog txuag ntau heev, tab sis kuj txo cov kev sib tw. Pov tseg thiab kev ua qias tuaj, kev piav ntxiv, luam tawm tuaj yeem ua qhov khoom siv ntawm tus kav hlau txais xov ntau dua, siv lwm lub luam ntawv, ntxiv rau daim ntawv lo thiab microchip tuaj yeem siv, kom cov txheej txheem RFID tsim tau sai.

Cov cwj pwm ua si yog ib qho tseem ceeb heev hauv kev luam ntawm RFID antennas. Feem ntau xws li cov phom sij xws li nyiaj los sis carbon. Nyob rau hauv xyoo tas los, cov chaw lag luam ntawm RFID cov cim tau raug kuaj tau lub feasibility ntawm kev siv xov tooj cua polymer rau kev luam tawm. Tus cwj pwm coj cwj pwm yog ib hom PTF pastes uas tsim los ntawm cov nyiaj thiab cov carbon, thiab PTF feem ntau pom muaj nyob rau hauv cov ntawv luam tawm Circuit Board. Vim qhov txo tus PTF tsawg (Table 4), nws yog qhov zoo tshaj plaws number case rau RFID cov cim npe, thiab cov PTF tsim los ntawm tooj. Txawm li cas los, vim hais tias tooj yog ceev heev, nws tsis haum rau kev siv. Rau RFID.

Vim qhov zoo tshaj plaws ntawm kev luam ntawv, ua ke nrog txoj kev loj hlob sai ntawm RFID, luam RFID antennas yuav coj dua tshiab kev ua lag luam rau kev lag luam luam. Qhov pom tseeb tshaj plaws yog tias RFID yuav hloov tus thawj barcode. Txoj cai bar code yog thawj coj ua lag luam loj ntawm lub lag luam luam ntawv. Tom qab siv lub npe ntawm RFID, luam tawm muaj lwm txoj hauj lwm tshiab - luam tawm nws lub kav hlau txais xov nrog tus cwjpwm. Tus nqi yeej ib txwm muaj kev khuam siab loj hauv kev txhawb zog ntawm RFID. Tam sim no, tus nqe ntawm RFID cov cim yog nruab nrab ntawm US $ 3 thiab US $ 6 ib duas. Ntawm chav kawm, tsis muaj teeb meem rau cov khoom tseem ceeb, tab sis nws yuav tsis ua hauj lwm rau cov khoom muag tsawg. Kev siv tus cwj pwm xaj hluav taws xob luam tawm RFID tag nrho cov kav hlau txais xov los yog lub voj voog, tsis yog tsuas muaj txiaj ntsig, tab sis kuj yog ib txoj hauv kev zoo los txo cov nqi, tab sis kuj txo cov pa phem ntawm ntau yam tooj liab thiab corrosive kua.

(3) Kev pom kev nkag mus rau hauv RFID kev siv tshuab los ntawm Drupa 2004 luam tawm exhibition

Nyob rau hauv xyoo 2004 Drupa exhibition, cov ntawv xovxwm nrog ntau cov txheej txheem yuav ci rau xyoo no. Los ntawm no, peb tuaj yeem pom tau tias cov khoom siv dag zog ntawm kev luam ntawv tseem zoo tuaj. Ntawm no, RFID tau dhau los ua ib qho tseem ceeb ntawm qhov kev nthuav dav no, xws li Flint Ink Inc. (Daim Duab 1) tau teeb tsa kev tsim ua haujlwm rau lub lag luam no thiab tau koom tes nrog MIT qhov chaw pib tsheb los tsim lub ntiaj teb RFID data collection network . , tsim kom muaj kev sib raug zoo. Flint Ink tau sib piv cov kab uas tau sau nrog cov khoom siv hluav taws xob ua rau cov kab ua tooj liab-etched hauv ntau hom xov tooj cua.
