NTAG215 vs NTAG213 vs NTAG216: Nigute wahitamo neza NFC Chip
Umuguzi yohereje ibisobanuro kubihumbi mirongo itanu. Ibikorwa byubuhanzi byashyizweho umukono, umurongo wurupfu wemejwe, idirishya ryo kugemura rirakosorwa, kandi umurongo wa chip kumurongo wubuguzi uravuga "NTAG216, kugirango kwaguka ejo hazaza." Ntamuntu uri mumurongo ukora ikintu cyose atitaye. Nyuma y'ibyumweru bitandatu ibirango bigeze, birakora neza, kandi ubukangurambaga bwandika mirongo ine - inyuguti ngufi ihuza muri chip hamwe na 888 byite yibikoresho byabakoresha. Ibicuruzwa byatwara amafaranga make kuri NTAG215, make nanone kuri NTAG213, kandi nta verisiyo ya kabiri ya chip.
Ibinyuranye nibyo imeri ihenze cyane. Porogaramu yamakarita yubucuruzi ya digitale isanzwe mubice bihendutse mumuryango, amato, hanyuma itsinda ryamamaza risaba kongeramo ibipimo bya UTM kuri buri URL. Amafaranga yishyurwa ntagihuye. Nta porogaramu ya porogaramu yo kwibuka hejuru, kandi umuti wonyine ni ugusubiza amakarita yumubiri kubantu basanzwe bafite imwe mu gikapu cyabo.
Nta na kimwe muri ibyo ari ubutumwa tubona kenshi, nubwo. Igikunze kugaragara cyane ni kigufi: porogaramu yavuze kwandika neza, kandi umusomyi ntacyo akora. Icyo nikibazo cya kodegisi kandi twarabyanditse bitandukanye. Byombi byavuzwe haruguru nibibazo byo guhitamo chip, kandi birakabije, kuko kodegisi irashobora gusubirwamo kandi chip ntishobora.
Bose uko ari batatu bava mu cyuho kimwe. Ibigereranirizo biboneka kuri NTAG213, NTAG215 na NTAG216 bihagarara kumeza yibuka, kandi imbonerahamwe yibuka ntabwo ibwira umuguzi umubare wa bytes bangahe umushahara wabo ukoresha, icyo urupapuro rwabigenewe rusiga bucece, icyo gutondekanya ibicuruzwa byinshi bya tagi ya NTAG215 byashyizwe ahagaragara, cyangwa uburyo bwo kwerekana ibicuruzwa biri muri chip muri lamin.
Icyo Umubare Wibice Bitatu Mugabane Mubyukuri
Mbere yuko itandukaniro rikwiriye kuganirwaho, bifasha kumenya uburyo butandukanye butandukanya ibi bice, kuko umugabane utangaje wo kugura impaka ukorwa kumitungo ihuriweho na bitatu.
NTAG213, NTAG215 na NTAG216 ni umuryango umwe wa silicon wo mu ruganda rumwe, wasohoye hamwe hamwe hamwe witwa NTAG21x. Bose uko ari batatu bubahiriza ihuriro rya NFC Ubwoko bwa 2 Tag hamwe na ISO / IEC 14443 Ubwoko A, bakora kuri 13.56 MHz, bohereza kuri 106 kbit / s, batwara numero yuruhererekane ya 7 -, kandi bitwaje imiterere ya ECC ishingiye kumyimerere. Intera yabo ikora yerekana intera imwe, kugeza kuri mm 100, yujuje ibyangombwa mumpapuro zamakuru bitewe nimbaraga zumurima na antenna geometrie (NXP NTAG213 / 215/216 urupapuro rwibicuruzwa). Imyitwarire ya terefone nayo irasa: buri terefone isoma imwe isoma uko ari itatu, kandi Ubwoko bwa 2 bwerekana ko ibyo ari ukuri bisobanurwa numubiri usanzwe aho kuba uwacuruza chip (Ihuriro NFC).
Ingaruka zifatika zikwiye kuvugwa nta nkomyi, kuko "biterwa no gusaba kwawe" nigisubizo kibi hano. Umuntu wese ukugurisha NTAG216 kubwumuvuduko, urwego, kwiringirwa, kuramba cyangwa guhuza terefone asobanura itandukaniro ritabaho. Kwibuka nibihinduka. Ibindi byose nigice kimwe.
Imbonerahamwe yo kwibuka, hamwe ninkingi Umuntu wese areka
Kugereranya ubunini bwa NTAG215 ubunini bwa barumuna bayo hafi ya buri gihe byerekana imibare itatu hanyuma igahagarara. Iyo mibare uko ari itatu irakwiriye, kandi nayo ntabwo yuzuye muburyo bufite akamaro iyo uteganya kwishyura umushahara aho gushakisha.

Imirongo ine na itandatu nimwe ikwiye guhagarara, kandi byombi biva kumurongo umwe nkumutwe wimibare.
Ubushobozi bwa kontineri ni enye - byte imiterere chip itwara kuva muri wafer, naho byte ya gatatu itangaza umusomyi uko umwanya wa NDEF uhari. Hagati - igice cyubushobozi byte itangaza 496 bytes kuri 504 byite yububiko bwabakoresha, naho igice kinini kiratangaza 872 kuri 888. Ikinyuranyo ni gito mumagambo yuzuye kandi ningaruka mubikorwa, kuko igikoresho gikoresha ubunini bwikibanza cya data kiva mubikoresho byububiko kizaba kibara imbibi zitari nziza, bityo ugasanga ahantu hafungiwe imbaraga hamwe nimpapuro zabugenewe. Encoding software yigeze kugeragezwa gusa igice cya 144-byte ntishobora kugaragara hejuru, kuko kuruhande rumwe imibare yombi irabyemera.
Niba ibyo umunani - byte kunyuranya bigutwara ikintu cyose biterwa nikintu kimwe, kandi birakwiye kumenya uruhande rwacyo urimo. Niba tags yawe irimo kodegisi ya terefone cyangwa kodegisi ya desktop ya stock yandika ubutumwa busanzwe bwa NDEF, software ikora offset kandi ntuzigera uyibona. Iraruma iyo umuntu yanditse kodegisi ye bwite, cyangwa agahuza iyariho kuva NTAG213 kugeza kuri NTAG215, ikanakura adresse yurupapuro rwiboneza mu mibare uhereye kubikoresho byabigenewe aho kuva mubice - gushakisha umubare. Nibyo rwose bibaho mugihe umushinga uzamutse murwego rwo kwibuka hagati -, nicyo gihe kimwe buriwese atiteguye kubikemura.
Mugihe turimo gukora imibare isobanutse, ikosorwa rimwe rirakwiye. Gusikana - kubara igisenge cyibihumbi mirongo itanu, ibihumbi magana abiri na magana atanu ibikorwa kubice bitatu bizenguruka cyane kurubuga rwacururizwagamo ibicuruzwa hanyuma bigakopororwa mubaguzi - bahura nigereranya buri mwaka. Ntabwo igaragara mu rupapuro rwabayikoze, kandi yicaye nabi iruhande rwumubare wihanganye washyizwe ahagaragara 100.000 wandika, ibyo bikaba bimwe kuri bitatu. Fata uwaguhaye isoko wese asubiramo scan - kubara nkumuntu usubiramo isoko aho gusoma isoko.
Guteganya Amafaranga Yishyurwa muri Bytes Mbere yuko Wiyemeza Igice
Dore imibare ifata ibyemezo byinshi bya NTAG215, kandi hafi yabantu bose ntibabitangaza, kuko kubitangaza bikuraho ibidasobanutse bituma - ibisobanuro byoroshye kugurisha.
Ubutumwa bwa NDEF ntabwo ari URL yawe. Mbere yuko inyuguti imwe ya aderesi ibikwa, agace gakoresha chip gatwara TLV ipfunyika, hanyuma umutwe wanditse, ubwoko - umurima muremure, umutwaro - umurima, hamwe nubwoko bwumurima. URI inyandiko noneho ikanda prefixes zisanzwe nka https: // www. muri byte imwe, itanga icumi kugeza kuri makumyabiri muriyo byite inyuma. Ku gice cya 144-byte arithmetic irakomeye bihagije kuburyo kwikuramo akenshi ari itandukaniro riri hagati yumutwaro uhuye nikosa ryuzuye kuri kodegisi.
Ikimara icyumba gisigaye ni gake URL. Ni inyongera. Inyandiko ya kabiri yanditse itwaye umuntu - ikirango gisomeka, inyandiko ya porogaramu ya Android bityo kanda ifungura porogaramu aho kuba mushakisha, inomero yuruhererekane yongewe kuri buri gice, gukurikirana ibipimo byongeweho mugihe ubukangurambaga bwahawe ikigo: buri kimwe muri ibyo gikurura ingengo yimari imwe, kandi buri kimwe gikunda gusabwa nyuma yicyemezo cyibikoresho byahagaritswe.
| Kwishura | Ingengo yimari ifatika | Igice gito gifashe |
|---|---|---|
| Ihuza rigufi, nta bipimo | 30-60 bytes | NTAG213 |
| URL yuzuye hamwe nibibazo byumugozi nibipimo bya UTM | 100-160 bytes | NTAG215 |
| URL wongeyeho inyandiko wongeyeho inyandiko isaba | 150-22 bytes | NTAG215 |
| VCard yuzuye hamwe na aderesi na nimero ebyiri za terefone | 350-500 bytes | NTAG215 |
| Wi - Ibyangombwa bya Fi wongeyeho URL itanga wongeyeho ikiranga igikoresho | 200-400 bytes | NTAG215 |
| Multi - inyandiko yishyurwa hamwe ninyandiko nyinshi zaho | 500 bytes no hejuru | NTAG216 |
Ibikorwa byacu bwite, kandi ubu ni bwo buryo bwo gutegeka buturuka gusa kuri kodegisi aho kuba ku rupapuro rwamakuru, ni inyuguti mirongo cyenda. Niba URL igenewe harimo buri kintu cyose ushobora kubona kirenze inyuguti mirongo cyenda, hagarika kwerekana igice cya 144 - byte hanyuma uzamuke intambwe; itandukaniro kuri buri gice hagati yibi byombi ni bito bihagije kuburyo bidakwiriye na rimwe gutwara ibyago byongeye kugaragara binyuze muri porogaramu. Urwo rugabano rurinda nkana, kandi impamvu ni uko atari kubara byte. Nibiteganijwe byerekana uko URL izakura mubuzima bwa tagi, kandi ibyo biteganijwe biterwa nibintu iyi ngingo idashobora kubona, harimo niba serialisation ikurikiranye cyangwa idahwitse ndetse niba ikigo kizatunga iyo cyerekezo. Ubukanishi bwo kwandika ibyo bytes, harimo ibikorwa bitatu bitandukanye porogaramu ya terefone igwa muri buto imwe, bikubiye mu nyandiko za mugenzi wawe kurigutangiza gahunda ya NFC mumiryango itandukanye ya chip.
Iyo Kugaragaza Hasi Kuva NTAG215 kugeza NTAG213 Numuhamagaro mwiza
Mburabuzi igitekerezo muri iki cyiciro gikoresha icyerekezo kimwe. Kwibuka byinshi bisoma nkicyumba kinini, icyumba cyumutwe gisoma nkumutekano, kandi igiciro cyiyongera kuri buri gice ni gito, nuko abaguzi bagenda hejuru. Hano hari impaka zifatika kurundi ruhande, kandi zikwiye ibirenze ibisobanuro.
Ikirangantego gishobora kuba ikintu cyamakuru cyangwa gishobora kuba icyerekezo. Iyo ari igitekerezo, ikintu cyonyine kibaho mububiko bwabakoresha ni adresse, ibirimo byukuri bicara kuri seriveri uyobora, kandi urashobora guhindura ibirimo kumunsi wo kuwa kabiri nyuma ya saa sita udakoze ku gice kimwe mumurima. Iyo ari kontineri, ibirimo biri muri laminate, kandi kubihindura bivuze ko wongeye kwandika hejuru ya tagi yumubiri cyangwa reissue. Hafi yamateka yacu yatumijwe inyandiko yoherejwe - icyifuzo cyo gutanga ntabwo ari inenge na gato: ni uguhindura aho ugana, kandi ihurira mumwaka wambere wa serivisi, mubisanzwe biterwa no kwimuka kurupapuro cyangwa kwimura ikigo. Buri kimwe muri ibyo byifuzo kirahendutse guhaza icyerekezo cyubaka kandi gihenze kububiko bwa kontineri, utitaye kumubare wigice kiri imbere.
Ibyo bishimangira kugereranya. Niba imyubakire yawe yerekana aho kuba ububiko, igice cya 144 - byte ntabwo ari ubwumvikane, nibisobanuro nyabyo, kandi igice cyo hagati ni kugura ubwishingizi kukibazo umushinga wawe umaze gukuraho. Igice cya 144-byte cyoherejwe mubunini bwumuryango kubwiyi mpamvu.
Impapuro - abaguzi bageraho ni igipimo cyibiciro, kandi nibyiza rwose: kuzamuka urwego rugura inshuro zigera kuri eshatu nigice ububiko bwabakoresha kuri premium yapimwe mubice bya cente mubunini. Ufatwa nkuruzitiro, ubwo ni ubwishingizi buhendutse. Ufatwa nkikintu cyumurongo, nigice cyonyine cyicyemezo gishobora guhindurwa muburyo bufite akamaro, kuko ushobora guhora ugaragaza hasi kurutonde rukurikira kandi ntushobora na rimwe gutondekanya kurubu.
Aho impaka zisubiye ni umutwaro ugomba kubaho nta guhuza. Iboneza ryamakuru ryasomwe numusomyi wa interineti, ibyangombwa bikoreshwa na sisitemu yashyizwemo idafite inyuma, inyandiko yo kubungabunga igomba kuba yemewe kurubuga rudafite ikimenyetso: muri ibyoherejwe tagi mubyukuri ni data base, kandi ububiko bwa NTAG215 buhinduka hasi aho kuba igisenge. Ikibazo cyo gushira mubishushanyo byawe ntabwo ari byite ukeneye uyumunsi. Nukumenya niba umuyoboro uboneka mugihe cyo gukanda, kandi ibyo birakwiye gutura kumpapuro mbere yubuguzi aho kuvumbura murubanza rwa mbere.
Ijambobanga, Funga Granularity nimbibi zitigera zigera kurupapuro rwihariye
Inzitizi enye kuri uyu muryango zanditse ariko ni gake zagaragaye mugihe cyo gutoranya, kandi buri imwe yahagaritse igishushanyo nyuma yo kugura umukono.
Iya mbere ireba kurinda. Ibice uko ari bitatu bitanga ijambo ryibanga rya 32 - hamwe na 16 - byemewe, kandi ijambo "ijambo ryibanga" rikora imirimo myinshi itize mubitabo bitanga isoko. Agaciro kanyujijwe muburyo busobanutse kandi bugenzurwa na chip, gating yandika kwinjira hanyuma uhitemo gusoma gusoma kuva kurupapuro watanze. Ibyo bihagarika umunyamuryango wandika tagi ireba rubanda hamwe na terefone, nikintu gifatika kandi cyingirakamaro. Ntabwo ari igenzura ryerekana, ntabwo irwanya igitero cyiyemeje, kandi ntigomba na rimwe kugaragara mu nyandiko isobanura iruhande rw'ijambo "umutekano". Porogaramu itanga ubunyangamugayo kubakiriya ba nyuma ikeneye igice gishingiye kuri AES, ntabwo kurinda ijambo ryibanga rya NTAG215 hamwe nibisobanuro bifatika bifatanye.
Icya kabiri, kandi ibi bitanga ibisubizo byinshi - ibisubizo byimbitse mumuryango, biza gufunga granularity. Gufunga kuri izo chip ntabwo ari kimwe. Ibintu bitatu byingirakamaro bifunga byitwikiriye igice cyasobanuwe cyagace kamakuru, kandi akarere gato buri kugenzura bigatandukana kubice: impapuro ebyiri kuri 144 - byte chip, impapuro cumi nagatandatu kuri ebyiri nini nini. Impapuro cumi na zitandatu ni mirongo itandatu - bytes enye. Imiterere ivanze rero kuri NTAG215, hamwe nakarere ka serial yakonjeshejwe muruganda hamwe nakarere kiyamamaza gasigaye kwandikwa, ni byiza ariko ni gake, kandi imbibi zombi zigomba kugwa kumurongo wa mirongo itandatu - bine-byte. Igishushanyo gikeneye umurima muto ufunze wegeranye n'umurima muto wanditse byoroshye kuri chip ntoya, ibyo bikaba bitandukanye cyane nibyo abaguzi biteze mugihe bazamutse kugirango bahinduke.
Inganda zikora inganda zitanga imbogamizi ya gatatu, kandi ni inzira aho kuba tekiniki. Porogaramu wandike urupapuro rwerekana kugirango ukoreshe neza izo dinamike zifunga ntabwo ari inyandiko rusange; bisaba amasezerano nuwabikoze no kugera kububiko bwabo bwateganijwe, imbogamizi yemejwe naba injeniyeri babo mu ihuriro ryabacuruzi (Umuryango NXP). Niba gufunga bishobora gukorwa neza mugice cyawe rero ni igice cyikibazo kijyanye numuyoboro wawe utanga, ntabwo kijyanye na silicon gusa. Birakwiye kubaza mbere yicyemezo kuruta nyuma.
Iya kane itanga ibarura ryakuweho aho gushushanya. Kurwanya Kurwanya - kurira kuri NTAG21x, byasobanuwe mu nyandiko nyirizina yabisabye AN13089, ikubiyemo agace ka OTP, gufunga bits hamwe na konti. Ntabwo ikubiyemo impapuro zabakoresha. Niba ikirangantego gisize umurima wa RF igice unyuze kumukoresha - kwibuka, ibyo bikaba bisanzwe kumurongo wimikorere igenda cyangwa mumaboko yumukoresha wububiko ukora vuba, chip ntacyo yemeza kubisigaye inyuma. Kurinda amakuru yumukoresha kurira - off ni progaramu - inshingano zurwego, kandi inzira iyo ari yo yose ya kodegisi yandika udasomye inyuma yanze guceceka iyo nshingano. Iyi ni imwe mu mpamvu zituma muri - umurongo wo kugenzura utabishaka hejuru y'ibihumbi bike.
Gutanga Icyiciro Mubyukuri birimo Chip NTAG215
Ngiyo abaguzi bafite ibyago biri hasi kandi bagomba kuza kumwanya wa kabiri. Ikirangantego gisoma neza kuri terefone ntakintu nakimwe kivuga kubijyanye na silikoni iri imbere, kandi gusimburwa muriki cyiciro byanditse aho kuba hypothettike: injeniyeri waguze ibirango bya NTAG21x binyuze mumiyoboro rusange yo kugurisha yabimenyesheje uruganda nyirizina ko buri cyitegererezo cyitwaye neza mubisobanuro, indorerwamo yibirindiro birimo, mugihe igenzura ryumwimerere ryasubije umukono utagaragara kandi ugaragaza ibice nka silicon. Uruganda rwatangaje igisubizo cyuko ibicuruzwa nkibi bidashyigikiwe kandi ntibigomba gushingirwaho kugirango bikoreshwe neza, kuko IC ubwayo ishobora kwibasirwa (Umuryango NXP).
Amasheki atatu agizwe nuburyo bukoreshwa bwinjira, kandi bukora muminota umwe kuri sample.
Tangira nigisubizo cya verisiyo. Chip izerekana ingano yububiko bwayo, ariko iratangaza ko ari intera aho kuba agaciro: igice cya 144 - byte kigwa hagati ya 128 na 256, igice cya 504-byte hagati ya 256 na 512, igice cya 888-byte hagati ya 512 na 1024. Gusoma kimwe rero bigabanya umwirondoro utarangije, kandi igisubizo kigomba gukemurwa ku mbonerahamwe yo kureba. Gusoma verisiyo rimwe hanyuma ukarangiza "iki cyiciro nukuri NTAG215" nigikorwa gikunze kugaragara mubicuruzwa, kandi ntabwo ari umwanzuro igisubizo gishyigikira.
Noneho reba umukono wumwimerere. Igice cyose cyukuri muri uyu muryango gitwara umukono wa 32-byte ECDSA hejuru ya UID, cyanditswe mugukora chip kandi gisomwa binyuze mubuyobozi bwabigenewe, gishobora kugenzurwa nurufunguzo rusange rwakozwe nuwabikoze. Igice cyananiwe kugenzura ntikiva muri fab isaba. Sobanukirwa icyo pasiporo yerekana, nubwo, kubera ko aha ariho igenzura risanzwe rigurishwa: umukono wemewe ugaragaza ko silicon ari ukuri, ntabwo aribyo bicuruzwa byarangiye. Silicon yukuri irashobora kugarurwa no gusubirwamo, kandi UID n'umukono byombi birasomeka, cheque rero ni irembo ryukuri kuri chip ntabwo ari kashe ya tamper kurirango.
Kurangiza wandika kandi usoma inyuma yumukoresha wuzuye. Iyi niyo ntambwe yonyine yemeza ubushobozi, kandi niyo ifata abaguzi basimbuye akenshi bahangayikishijwe, igice gito cyatangiwe inyemezabuguzi nini. Niba 504 bytes zinjiye na 504 bytes zikagaruka, ikibazo kirakemutse.
Niba ushobora gukora iryo genzura rya gatatu kuri buri gice aho kuba kuri sample ni ikibazo kijyanye n'umurongo utanga isoko, ntabwo kijyanye nishami rya QC. Iwacu iricara hagati yo guhuza chip no guterana kwanyuma kumirongo itanu yumusaruro muruganda rwa m6 3,600, ifite ubushobozi bwo guhuza imashini hejuru ya chipi 100.000 kumunsi, aribyo bituma 100% basoma - inyuma bihendutse kuruta imyitozo yo gutoranya; igice cyananiwe kwangwa mbere yuko kigera ku gupakira, kandi ubwato bwoherejwe hamwe na mapping dosiye ihuza buri UID nibirimo byandikiwe. Kuburyo bwo gutsindwa byegeranye, aho kwandika raporo byerekana intsinzi kandi umusomyi ntacyo akora, ibyo twanditse kurikuki icyapa gikonjesha gisoma neza kandi bikananirana kumuryangogutwikira urutonde rwo gusuzuma.
Icyo cheque eshatu zidashobora kukubwira niho washyiraho urwego rwo kwemererwa, kandi iyo mibare yubatswe rwose - yihariye. Kurwanya icyuma - icyuma, ikarita ya PVC yacapishijwe hamwe nigitambara cyometse ku ntoki ntibitwara kimwe binyuze kumurongo umwe wa kodegisi, kandi igipimo cyo kwangwa kuri umwe ni ibendera ritukura ku rindi.
Soma Urutonde Nikibazo cya Antenna, Ntabwo Ikibazo Umubare Umubare
Icyifuzo gisubirwamo kigeze nyuma yikigeragezo cyumurima utengushye: tags yasomwe kuri milimetero cumi neshanu, dukeneye mirongo itatu, nyamuneka vuga ikintu kimwe kuri NTAG216. Kuzamura ntabwo bizatanga. Ibice uko ari bitatu bitwara intera imwe ikora, kandi ibyo bisobanuro byanditswe nkibisobanuro byerekeranye nimbaraga zumurima na antenna geometrie aho kuba nkumutungo wa chip.
Guhuza bigengwa na tagi antenne ifunze ahantu hamwe no guhindukira kubara, ukurikije icyo tagi yashizwemo, hamwe numurima wabasomyi. Mubyitegererezo byacu bwite dusanzwe twubaka NTAG215 imwe ipfa mukirango cya mm 25 cyumuzingi no mukarita ya CR80 yinjizamo umukiriya umwe, kandi format zombi ntizisoma kimwe: antenne yikarita ikubiyemo inshuro nyinshi ubuso bwa label antenna, kandi intera ikurikira iyo mibare cyane kuruta uko ikurikira ikintu cyose kiri kumpapuro zamakuru. Hagati yimibare itatu, hagati aho, itandukaniro ni zeru. Ibyuma inyuma yikimenyetso bitandukanya antenne kandi bigasenyuka intera utitaye kuri chip ihujwe nayo, nicyo gipimo cya ferrite mubikorwa byo kurwanya - byubaka kugirango bikemuke.
Ingaruka zo kwandika ibisobanuro biroroshye bihagije. Urutonde rwo gusoma ruri muburyo bwo kuganira, hamwe na label ya diameter, substrate no kuzamuka hejuru, kandi bigomba kwemezwa kumitungo yabasomyi izashyirwaho mubyukuri. Ntabwo ari mubiganiro bya chip na gato, kandi uwatanze isoko asubiza ikibazo cyinshi atanga umubare munini wigice ntashobora kumva cyangwa kudasoma. Niba imiterere irakinguye, iimiterere na label imiterere twubaka ibirango bya NTAG215 murini ahantu heza ho gutangirira icyo kiganiro.
Guhuza Igice Kuri Kohereza
Ibintu byose byavuzwe haruguru bisenyuka mubibazo hamwe ninyongeramusaruro eshatu: ni bangahe bytes umutwaro ukenera, niba umuyoboro uhari kuri kanda, kandi niba porogaramu itanga ikirego cyumutekano.

Kugaragaza NTAG215 yo kwemeza ibicuruzwa bitanga fagitire yibikoresho bikomeza isuzuma ryamasoko bikananirwa gusuzuma umutekano. Niba ipaki yawe ibwira umuguzi ko igikanda cyerekana ko ikintu ari ukuri, chip igomba kwemeza kode kandi ikanatanga ubutumwa inyuma yawe ishobora kugenzura nkibishya; NTAG 424 ADN ibikora hamwe nabakiriya - bafashe urufunguzo rwa AES hamwe na URL- kanda URL ifite imbaraga, kandi ni icyiciro cya silicon gitandukanye ningengo yimari itandukanye. Kuvumbura icyo gisabwa nyuma yo gukoresha ibikoresho ni verisiyo ihenze cyane yibi biganiro byose, kandi ubuyobozi bwingenzi buzana nabwo bukubiye mu ngingo ya mugenzi uhujwe hejuru.
Ku ikarita hamwe nimpamyabushobozi yanyuma yimbonerahamwe, icyemezo cya substrate mubisanzwe kigwa mbere yicyemezo cya chip, kandiamakarita yera ya PVC yeraniho porogaramu nyinshi zamakarita yubucuruzi zitangirira.
Niki Mubyukuri Gushiraho Ntarengwa Ntarengwa ya NTAG215 Tagi
Ikibazo kimwe gihitamo niba kimwe muribi byavuzwe haruguru gikora, kandi niyo ngingo imwe yo kugereranya itigera isubiza: ubwinshi bwa NTAG215 butumiza umubare muto biterwa niki?
Ntabwo ari chip. Chips muri uyu muryango ni silicon yibicuruzwa byaguzwe kuri reel, kandi nimero eshatu zigizwe neza nubutaka bumwe. Ntarengwa yashyizweho nintambwe yo guhindura: antenne etch cyangwa icapiro, guhuza gupfa, kumurika, no hejuru yibikoresho byose kumiterere yarangiye. Ikirangantego kizengurutse gikora ku rupfu kiriho ntigikeneye ibikoresho bishya kandi gitwara hasi. Umugenzo - shusho ya epoxy tag, ikarita yacapwe ifite imiterere ya bespoke, cyangwa anti - kubaka ibyuma hamwe na ferrite layer buriwese yongeramo irembo ryibikoresho, hasi ikagenda nayo. Ibicuruzwa bibiri kuri chip imwe ya NTAG215 birashobora rero kwicara gutondekanya ubunini butandukanye kumubare muto gusa kuko umwe yongeye gukoresha ibikoresho undi ntabikora.
Ingaruka zifatika kubaguzi nuko kubaza "MOQ yawe niki" bitanga igisubizo kidafite akamaro kugeza imiterere yitiriwe, kandi ko inzira yihuse yo kugabanya byibuze ni ukwemera imiterere yimigabane aho kuganira. Igihe cyo kuyobora cyitwara kimwe kandi kubwimpamvu imwe. Aho rwose inyubako yawe yicaye biterwa nimiterere, uburyo bwo gucapa kandi niba kodegisi hamwe na serialisation biri murwego, ibyo ni amagambo aho kuba ingingo.
Niba ibisobanuro bimaze gutegurwa, tuzabisubiramo turwanya imbogamizi ziri hejuru hanyuma dushyireho ibendera ibitazarokoka umusaruro, kandi ingero z'ubuntu zirahari kugirango icyemezo gishobore kugeragezwa kubasomyi bawe na terefone yawe aho kuba iwacu. Imiterere tubanziriza - gahunda no kugenzura munzu - urutonde munsiurutonde rwa NFC, kandi niba imiterere yo kwishura nubunini bimaze gukosorwa urashoboraohereza hejuru kugirango bakore chip na kodegisi.
Ibibazo
Ni kangahe NTAG215 ishobora gufata?
504 bytes yububiko bwabakoresha, muribwo ubushobozi bwububiko butangaza 496 bytes nkubushobozi bwa NDEF, naho igipfunyika cya NDEF kimara igice cyacyo mbere yuko ibikubiyemo bibikwa.
Nshobora kuzamura kuva muri NTAG213 kugeza kuri NTAG215 nyuma yo koherezwa?
Oya. Chip yashizwe mubikorwa, kuburyo amahitamo arimo kugabanya imizigo, kwimura data seriveri - kuruhande, cyangwa kohereza tagi kumurongo ukurikira.
Ese NTAG213, NTAG215 na NTAG216 bifite intera zitandukanye zo gusoma?
Oya. Bose uko ari batatu bitwara intera imwe ikora, kandi intera nyayo igenwa nubunini bwa antenne, substrate hamwe nubuso bwubuso.
Nigute nshobora kwemeza ko icyiciro kirimo chip ya NTAG215?
Kemura igisubizo cyibisubizo kumeza yo kureba, genzura umukono wumwimerere wa ECC urwanya urufunguzo rusange, hanyuma wandike hanyuma usome inyuma ububiko bwuzuye bwabakoresha kugirango wemeze ubushobozi.
Ese kurinda ijambo ryibanga rya NTAG215 birahagije kugirango hemezwe ibicuruzwa?
Oya. 32 - ijambo ryibanga ni igenzura ryinjira mumarembo yo kwandika no gusoma kubushake, kandi porogaramu zitanga ikirego gikeneye ADN ya NTAG 424 cyangwa ikindi gice gishingiye kuri AES.
Niki gishyiraho umubare ntarengwa wateganijwe kuri tagi ya NTAG215?
Intambwe yo guhindura no gukoresha ibikoresho, ntabwo ari chip. Imiterere yimigabane itwara hasi; imiterere yihariye, bespoke icapye imiterere na anti - ibyuma byubaka buri kimwe kongeramo irembo ryibikoresho bizamura.
