RFID, izina ryuzuye ni Kumenyekanisha Radio Frequency Identification. Nubuhanga budasanzwe bwo kumenyekanisha bwikora burahita bwerekana ibintu bigamije kandi bukabona amakuru ajyanye nibimenyetso bya radio. Igikorwa cyo kumenyekanisha ntigisaba intoki kandi gishobora gukorera ahantu hatandukanye. Tekinoroji ya RFID irashobora kumenya ibintu byihuta byihuta kandi ikamenya tagi nyinshi icyarimwe, bigatuma ibikorwa byihuta kandi byoroshye.

Ikirangantego cya RFID (Radio Frequency Identification) ni tekinoroji idahuye ikorana buhanga ihita imenya ibintu igamije kandi ikabona amakuru ajyanye nibimenyetso bya radiyo. Igikorwa cyo kumenyekanisha ntigisaba ubufasha bwintoki. Utumenyetso dusanzwe tugizwe na tagi, antene, nabasomyi. Umusomyi yohereza ibimenyetso bya radio yumurongo wa radiyo runaka binyuze muri antenne. Iyo tagi yinjiye mumashanyarazi, imbaraga zashizweho zibyara ingufu kugirango zohereze imbaraga no kohereza amakuru yabitswe muri chip kubasomyi. Umusomyi asoma amakuru, arayandika, kandi yohereza amakuru kuri mudasobwa. Sisitemu itunganya.

Ikirango cya RFID gikora ku buryo bukurikira:

1. Nyuma ya label ya RFID yinjiye mumashanyarazi, yakira ibimenyetso bya radio yumurongo woherejwe numusomyi wa RFID.

2. Koresha imbaraga zabonetse mumashanyarazi yatanzwe kugirango wohereze amakuru yibicuruzwa bibitswe muri chip (Passive RFID Tag), cyangwa wohereze witonze ikimenyetso cyumurongo runaka (Tagi ya RFID Tag).

3. Umusomyi amaze gusoma no gusobanura amakuru, yoherejwe muri sisitemu nkuru yamakuru kugirango atunganyirize amakuru.

Sisitemu yibanze ya RFID igizwe nibice bitatu:

1. RFID Tag: Igizwe no guhuza ibice hamwe na chip. Buri tagi ya RFID ifite code yihariye ya elegitoronike kandi ifatanye nikintu kugirango tumenye intego. Bikunze kumenyekana nkibikoresho bya elegitoronike cyangwa ibimenyetso byubwenge.

2. Antenna ya RFID: itanga ibimenyetso bya radiyo yumurongo hagati ya tagi nabasomyi.

Muri rusange, ihame ryakazi rya RFID nugukwirakwiza ibimenyetso bya radiyo yumurongo kuri tagi ukoresheje antene, hanyuma tagi ikoresha ingufu zabonetse numuyoboro watewe no kohereza amakuru yibicuruzwa bibitswe muri chip. Hanyuma, umusomyi asoma amakuru, arayanga kandi yohereza muri sisitemu nkuru yamakuru akora gutunganya amakuru.

Ibiranga RFID mubusanzwe bifite ahantu ho kubika cyangwa ibice bitandukanye bishobora kubika ubwoko butandukanye bwo kumenyekanisha hamwe namakuru. Ubwoko butandukanye bwo kwibuka bukunze kuboneka muri tagi ya RFID ni:

1. TID (Tag Identifier): TID ni ikiranga kidasanzwe cyagenwe nuwakoze tagi. Nibisomwa gusa byibukwa birimo numero yihariye yuruhererekane nandi makuru yihariye kurirango, nka kode yabayikoze cyangwa ibisobanuro birambuye. TID ntishobora guhindurwa cyangwa kwandikwa.

2. EPC (Kode y'ibicuruzwa bya elegitoroniki): Ububiko bwa EPC bukoreshwa mukubika ibiranga bidasanzwe ku isi (EPC) bya buri gicuruzwa cyangwa ikintu. Itanga kode isomeka kuri elegitoronike yerekana idasanzwe kandi ikurikirana ibintu bitandukanye murwego rwo gutanga cyangwa sisitemu yo gucunga ibintu.

3. Kwibuka UKORESHEJWE: Ububiko bwumukoresha nubusobanuro bwumukoresha wasobanuwe mububiko bwa RFID bushobora gukoreshwa mukubika amakuru yihariye cyangwa amakuru ukurikije porogaramu cyangwa ibisabwa byihariye. Mubisanzwe gusoma-kwandika kwibuka, kwemerera abakoresha bemerewe guhindura amakuru. Ingano yukoresha yibuka iratandukanye bitewe nibiranga tagi.
