I-RFID (i-Radio Frequency Identification), umgaqo wayo unxibelelwano lwedatha olungaqhagamshelani phakathi komfundi kunye nethegi ukufezekisa injongo yokuchonga ekujoliswe kuyo.Ukuba nje iyindlela yerediyo yerediyo, kwaye inokuchongwa ngolu hlobo, ibalwa njengodidi lwe-RFID.Ngokwe-frequency, inokuthi yahlulwe ngokubanzi ibe yi-frequency ephantsi, i-high frequency, i-ultra-high frequency, i-2.4G njalo njalo.I-RFID isetyenziswa ngokubanzi, kunye nezicelo eziqhelekileyo ezibandakanya ulawulo lwezilwanyana, ulawulo lwezithuthi, ukuzenzekelayo komgca wemveliso, ulawulo lwempahla, ulawulo lwabasebenzi, kunye nokhathalelo lwezonyango oluhlakaniphile.

Itekhnoloji ye-NFC (ekufuphi noNxibelelwano lweNdawo) yaqala emva kwexesha elide kune-RFID.Yayibuchwephesha obufutshane bonxibelelwano olungenazingcingo olukhuthazwa ikakhulu nguPhilips, uNokia kunye noSony malunga no-2003.I-frequency yokusebenza yi-13.56MHz, kwaye izinga lonxibelelwano yi-106kbit / sec ukuya kwi-848kbit / sec.Ngefowuni ephathwayo njengomphathi, isicelo sekhadi le-IC elingenakuqhagamshelwa lidityaniswe nefowuni ephathwayo, kwaye iindlela ezintathu zesicelo sekhadi, umfundi kunye nenqaku ukuya kwindawo zisetyenziselwa ukuhlawula intlawulo yeselula, usetyenziso lweshishini, ukutshintshiselana ngenqaku, ithikithi lombane. , ukuqondwa kwesazisi, ukuchasa ukwenza umgunyathi, ukuthengisa, njl.

I-RFID ithetha ngokulula ukubamba isekethi ye-RFID equlethe inxalenye yefrikhwensi yerediyo ye-RFID kunye ne-antenna loop kwinto ethile.Emva kokuba into ethwele ithegi ye-RFID ingene kwindawo ethile yamagnetic esetwe ngokufanelekileyo, iya kuthumela umqondiso wefrikhwensi ethile, kwayeUmfundi weRFIDunokufumana ulwazi olubhaliweyo kwinqaku ngaphambili.Oku kufana nebheji ejinga entanyeni yabasebenzi, kwaye ungumphathi wakhe.Xa engena kumgca wakho wokubona, unokwazi igama lakhe, umsebenzi kunye nolunye ulwazi, kwaye unokuphinda ubhale umxholo webheji yakhe.Ukuba i-RFID kukuba umntu unxibe ibheji ukuze abanye bamqonde, ngoko i-NFC kukuba abantu ababini banxibe iibheji, kwaye banokutshintsha ngokungekho mthethweni umxholo webheji emva kokubonana, kwaye utshintshe ulwazi olufunyenwe kwelinye iqela.I-NFC kunye ne-RFID zijongeka zifana kumgangatho womzimba, kodwa eneneni ziinkalo ezimbini ezihluke ngokupheleleyo, kuba i-RFID ibuchwephesha bokuchonga, ngelixa i-NFC ibuchwephesha bonxibelelwano.Umahluko othile ubonakaliswa kule miba ilandelayo

1. I-frequency yokusebenza: i-NFC frequency igxininiswe kwi-13.56MHz, ngelixa i-RFID iquka i-active (2.4G, 5.8G), i-semi-active (125K, 13.56M, 915M, 2.4G, 5.8G), kunye ne-RFID esebenzayo.Eyona ixhaphakileyo yiRFID yokwenziwa, enokuthi ihlulwe ibe yi-frequency ephantsi (125KHz / 134.2KHz), i-frequency ephezulu (13.56MHz) kunye ne-ultra-high frequency (860-960) i-frequency bands ngokwe-frequency.

2. Imowudi yokusebenza: I-NFC idibanisa umfundi wekhadi ongaqhagamshelwanga, ikhadi elingenakuqhagamshelwa kunye nemisebenzi yontanga kwi-chip enye, ngelixa i-rfid kufuneka iquka umfundi kunye nethegi.I-RFID inokuqonda kuphela ukufundwa kunye nokugwetywa kolwazi, ngelixa iteknoloji ye-NFC igxininisa ukusebenzisana kolwazi.I-NFC ixhasa zombini indlela yokufunda-ukubhala kunye nemodi yekhadi;kwi-RFID, umfundi wekhadi kunye nekhadi elingenakuqhagamshelwa zizinto ezimbini ezizimeleyo kwaye azikwazi ukutshintshelwa.I-NFC ixhasa imo ye-P2P, i-RFID ayixhasi imo ye-P2P.

3. Umgama wokusebenza: Umgama wokusebenza we-NFC ngokwethiyori ngu-0 ~ 20cm, kodwa ekufezekisweni kwemveliso, ngenxa yokusetyenziswa kweteknoloji ekhethekileyo yokunciphisa amandla, umgama wokusebenza ngu-0 ~ 10cm kuphela, ukwenzela ukuba kuqinisekiswe ngcono ukhuseleko. yeshishini;Ekubeni i-RFID inezandi ezahlukeneyo, umgama wayo wokusebenza uyahluka ukusuka kwiisentimitha ezimbalwa ukuya kumashumi eemitha.

4. Iprothokholi esemgangathweni: Iprothokholi yonxibelelwano esisiseko ye-NFC iyahambelana nomgangatho wonxibelelwano osisiseko we-RFID yefrikhwensi ephezulu, oko kukuthi, iyahambelana nomgangatho we-ISO14443/ISO15693.Itekhnoloji ye-NFC ikwachaza iprothokholi yomgangatho ophezulu ngokwentelekiso, njenge-LLP, NDEF kunye ne-RTD, njl., ngelixa i-RFID protocol inokuxhasa i-ISO 11784&11785, ISO14443/ISO15693, kunye ne-EPC C1 GEN2/ISO 18000-6C kunye neminye imigangatho ngokwe iifrikhwensi ezahlukeneyo.Nangona iteknoloji ye-NFC kunye ne-RFID zahlukile, iteknoloji ye-NFC, ngakumbi iteknoloji yonxibelelwano esisiseko, ihambelana ngokupheleleyo nobuchwepheshe be-RFID obuqhelekileyo.Ke ngoko, kwintsimi yesicelo se-RFID ephezulu, itekhnoloji ye-NFC nayo ingasetyenziswa.

5. Ulwalathiso lwesicelo: I-RFID isetyenziswe ngakumbi kwimigca yokuvelisa, i-warehousing logistics, ulawulo lwempahla kunye nezinye izicelo, ngelixa i-NFC isebenza kulawulo lokufikelela, amakhadi ebhasi, intlawulo yeselula njl.
