NFC gaw 13.56 megahertz kaw dung nga ai. Hpa majaw nga yang, -frequency kaba ai RFID gaw band langai hpe sha zing da ai. Shai hkat ai lam: NFC gaw peer-de-peer atsam hpe jat bang ya ai. Active device lahkawng gaw data hpe nhtang nhtang galai shai mai ai. Standard RFID gaw hti ai wa-ga shaga ai-shawng -tag hpe san jep ai shaloi sha htai ya ai.

 

Sony hte Philips Semiconductors ni gaw 2002 ning March shata hta hpaji masa hpe ka da ai rai nna, NFC Forum hpe 2004 ning March shata hta Nokia hpe masum ngu na hpaw ninghtan ai hpung hku nna hpaw ninghtan wa sai. Philips gaw shi a semiconductor daw hpe NXP ngu nna 2006 ning hta hpaw hpang wa sai rai nna, shawng ningnan lang na hpaga yumga galaw na matu NFC phone Nokia a 6131 hpe dai shaning hta sha shapraw dat sai. Android gaw 2010 ning hta Nexus S hte hpaw hpang wa ai rai nna, Apple gaw 2014 ning September shata hta iPhone 6 du hkra n hkap la ai.

 

Range gaw shanhte hpe lam amyu myu a matu akyu rawng shangun ai. RAIN tags ni hpe meter law law tsan ai kaw nna hti mai ai. Laika hti ai ni gaw 860 kaw nna 960 megahertz du hkra RF n-gun hte shara langai hpe hka kaba shangun ai; passive tags ni gaw shanhte a mahtai hpe n-gun jaw na matu dai n-gun hpe dan la ma ai. Active tags ni gaw battery ni hpe gun nna, matut nna shalai ya ai. NFC gaw 4 centimeters grup yin hta maxes pru wa ai-dai hpe lachyum shapraw ra ai daram ni ai.

 

Transfer galaw ai lawan ai lam gaw Bluetooth hte n shingjawng lu ai. NFC gaw second mi hta 424 kilobits daram sha rai nga ai. Bluetooth 2.1 gaw 2.1 megabit du ai. Version 5 gaw grau lawan ai hku galaw nga ai. Raitim NFC gaw second shi hta na langai daram hta pairing sequence n nga ai sha matut mahkai nga ai. Google gaw dai shim lum lam a grup yin hta Android Beam hpe galaw da ai. Hpang e dai feature hpe sat kau ma ai.

 

Walmart a supplier mandate ni gaw 2020 ning kaw nna jat wa sai, bu hpun palawng ni gaw shawng nnan kaw nga ai. 2022 ning hta nta arung arai ni, ginsup arai ni, electronic arung arai ni, ginsup arung arai ni hkan nang wa ai. 2024 ning du hkra grau nna general merchandise category ni hpe hpaw hpang wa ai. 2000 ning lapran hta, Walmart gaw shawng na RFID push hpe shakut ai shaloi, shanhte gaw 30 cents daram manu jahpu jaw nna, hkrat sum ai lam ni grai law ai majaw, supplier ni pru mat wa ma ai.

 

Payment terminal hpe hkap la ai lam hpe hkan tam na matu grau yak ai. NFC gaw shingdu kaw bungli galaw ai. Nang tap dat yang, charge galaw ai. Visa, Mastercard hte Amex ni gaw shanhte a matut mahkai lam n nga ai npawt nhpang hpe ISO/IEC 14443 grup yin hta gawgap da ai, dai gaw 13.56 megahertz layer hta NFC hte shingdaw ai makau grup yin card madang re. NFC Forum a masat da ai lam ni gaw 14443 hpe madung tawn nna, data hpe gram lajang na matu NDEF zawn re ai application-madang na tara ni hpe jat bang da ai.

 

Laika hti ai ladat n bung ai. RFID hti ai antenna gaw second loi mi laman hta latsa daram na ai tag ni hpe inventory galaw lu ai-dai gaw sutdek (sh) sutdek kata na cycle jahpan ni a matu akyu rawng ai. NFC gaw langai lang hta transaction langai hpe galaw ya ai. Dai pat shingdang ai lam gaw checkout line ni hte htap htuk tim, garan gachyan ai shara langai hpe shayawm kau na re.
