Zomwe Ma Tag a NFC Amatanthauza: Buku Loyamba la 2026

 

Yankho Lachidule: Zomwe NFC Tag Imachita

 

NFC imayimiraNear Field Communication. Ndiukadaulo waufupi-wosiyanasiyana wopanda zingwe womwe umalola zida ziwiri kusinthana pang'ono data ikasungidwa mkati mwa ma centimita angapo.

 

Chizindikiro cha NFC ndi kachipangizo kakang'ono, kopanda mawu, nthawi zambiri chomata, khadi, kapena chizindikiro, chomwe chimakhala ndi zigawo ziwiri zazikulu: kachipangizo kakang'ono ndi mlongoti. Chipchi chimasunga data (URL, string string, contact information, or encoded command), ndipo mlongoti umathandiza kuti datayo itumizidwe popanda ziwaya ku chipangizo choyatsidwa ndi NFC{1}} monga foni yamakono.

 

Ngati munayamba mwadzifunsapo kuti "tag ya NFC yapezeka" imatanthauza chiyani pa foni yanu, zimangotanthauza kuti wowerenga NFC wa foni yanu adatenga chizindikiro kuchokera pa tag yapafupi ndipo ali wokonzeka kukonza chilichonse chomwe chilipo: ulalo wapaintaneti, khadi yolumikizirana, kapena pempho lolipira.

 

Mawu oti "tag" amachokera ku lingaliro lofanana ndi lachikwama kapena mtengo wamtengo: ndi chizindikiro cholumikizidwa ndi chinthu chomwe chimakhala ndi chidziwitso. M'mawu a NFC, chizindikirocho chimalumikizana ndi digito m'malo mongowoneka.

 

NFC Forum, mgwirizano wamakampani wokhazikitsidwa ndi NXP Semiconductors, Sony, ndi Nokia, imatanthauzira miyezo yomwe imatsogolera momwe ma tag a NFC amalankhulirana. Miyezo iyi, kuphatikiza ISO/IEC 14443 ndi ISO/IEC 18092, iwonetsetsa kuti tag ya NFC yopangidwa mufakitale imodzi ikhoza kuwerengedwa modalirika ndi foni yamakono yopangidwa mbali ina ya dziko lapansi.

 

Kodi ma tag a NFC amagwira ntchito bwanji? (Chosavuta)

 

Ma tag a NFC alibe mabatire. Iwo samangokhala chete. Ndiye amatumiza bwanji deta?

 

Yankho ndiloelectromagnetic induction, mfundo yomweyi yomwe imathandizira ma charger amafoni opanda zingwe. Nayi ndondomekoyi m'mawu osavuta:

• Mumabweretsa wowerenga NFC pafupi ndi tag.Wowerenga nthawi zambiri amakhala foni yam'manja, malo olipira, kapena scanner yolowera.
• Wowerenga amapanga gawo laling'ono lamagetsiimagwira ntchito pa 13.56 MHz, ma frequency ovomerezeka padziko lonse lapansi.
• Mlongoti wa tagi umagwira mphamvu kuchokera m'mundawu.Mphamvu iyi ndi yokwanira kulimbitsa chip mkati mwa tag.
• Chip imatsegula ndikutumiza deta yake yosungidwakwa owerenga posintha gawo la electromagnetic.
• Owerenga amakonza detandikuyambitsa kuchitapo kanthu: kutsegula tsamba, kumaliza kulipira, kapena kutsegula chitseko.

 

 

Kusinthana konseku kumachitika mkati mwa pafupifupi 10 centimita (pafupifupi mainchesi 4) ndipo kumatenga nthawi yochepa sekondi imodzi. Kutalika kwafupi ndi dala. Imawonetsetsa kuti kuyanjana kwa NFC kumachitika mwadala. Muyenera kubweretsa zida ziwiri pafupi, zomwe zimachepetsa chiopsezo cha kusinthana kwa data mwangozi kapena kosaloledwa.

 

Chifukwa ma tag a NFC amapeza mphamvu kuchokera kwa owerenga, alibe magawo osuntha ndipo alibe batire lotha. Tagi yopangidwa bwino-ya NFC imatha kugwira ntchito kwa zaka zambiri, pomwe opanga ma chip otsogola monga NXP amafotokozera kusungidwa kwa data kwa zaka 10 ndikulemba kupirira kwa ma cycle 100,000 mokhazikika.

 

Ma Tag a NFC vs. RFID vs. QR Codes: Pali Kusiyana Kotani?

 

Ichi ndi chimodzi mwa mfundo zofala kwambiri zosokoneza kwa oyamba kumene. Ma code a NFC, RFID, ndi QR onse amagwira ntchito yofanana, kulumikiza zinthu zakuthupi ndi chidziwitso cha digito, koma amagwira ntchito mosiyana kwambiri.

 

NFC kwenikweni ndi kagawo kakang'ono ka RFID.RFID (Radio Frequency Identification) ndi banja laukadaulo lambiri. Imakhala ndi ma frequency osiyanasiyana, kuyambira 125 kHz otsika-ma tag omwe amagwiritsidwa ntchito potsata nyama mpaka 900 MHz ultra-pamwamba-ma tag omwe amagwiritsidwa ntchito posungira katundu. NFC imagwira ntchito makamaka pa 13.56 MHz (mafupipafupi) ndipo imatanthauzidwa ndi njira zowonjezera zoyankhulirana zomwe zimakhazikitsidwa ndi NFC Forum.
