NFC

Background & Application

NFC: Iyo pfupi-yekure-frequency isina waya yekutaurirana tekinoroji inobvumira isiri-yekubata-nzvimbo-kune-nzvimbo yekufambisa data pakati pemidziyo yemagetsi, kuchinjana data mukati mechinhambwe che10cm. Iyo NFC yekutaurirana system inosanganisira maviri akazvimirira zvikamu: NFC muverengi uye NFC tag. Muverengi weNFC ndicho chikamu chinoshanda chesisitimu iyo "inoverenga" (kana maitiro) ruzivo rwusati rwatanga imwe mhinduro. Inopa simba uye inotumira NFC mirairo kune inongoita chikamu cheiyo system (kureva iyo NFC tag). Kazhinji, pamwe chete ne microcontroller, muverengi weNFC anopa simba uye kuchinjana ruzivo neine imwe kana kupfuura NFC mavara. Muverengi weNFC anotsigira akawanda maRF mapuroteni uye maficha uye anogona kushandiswa mumatatu akasiyana modhi: kuverenga/kunyora, peer-to-peer (P2P) uye kadhi emulation. Iyo yekushanda frequency bhendi yeNFC ndeye 13.56 MHz, iyo ndeye yakakwira frequency, uye mitemo yeprotocol ndeye ISO/IEC 14443A/B uye ISO/IEC15693.

NFC zvinyorwa zvine huwandu hwakasiyana hwekushandisa, sekubatanidza uye kugadzirisa, maposta ekushambadza, anti-yekunyepedzera, nezvimwe.

1.Pairing & Debugging

Nekunyora ruzivo rwakadai sezita nepassword yeWiFi kune iyo NFC label kuburikidza neNFC muverengi, nekuisa iyo label panzvimbo yakakodzera, chinongedzo chinogona kugadzirwa nekungoisa maviri eNFC-inogonesa zvishandiso padhuze. Pamusoro pezvo, NFC inogona kukonzeresa mamwe maprotocol akadai seBluetooth, ZigBee. Pairing inonyatsoitika muchikamu chechipiri uye NFC inoshanda chete kana uchinge waida, saka hapazove netsaona yekubatanidza mudziyo uye hapazove nechero mudziyo unopokana senge Bluetooth. Kutumira zvishandiso zvitsva kana kuwedzera network yako yekumba zvakare zvakareruka, uye hapana chikonzero chekutsvaga chinongedzo kana kuisa password.

Kuongororwa kweKusarudzwa Kwechigadzirwa

Chip: Inokurudzirwa kushandisa NXP NTAG21x series, NTAG213, NTAG215 neNTAG216. Iyi nhevedzano yemachipisi inoenderana neNFC Type 2 standard uye zvakare inosangana ne ISO14443A standard.

Antenna:NFC inoshanda pa13.56MHz, ichishandisa aluminium etching process coil antenna AL+PET+AL.

Glue: Kana chinhu chinobatiswa chakatsetseka uye nharaunda yekushandisa yakanaka, inodhura-inopisa inopisa inonyungudutsa glue kana mvura glue inogona kushandiswa. Kana nharaunda yekushandiswa yakakasharara uye chinhu chinobatika chakakasharara, mafuta glue anogona kushandiswa kuita kuti chisimbe.

Surface material: Pepa rakavharwa rinogona kushandiswa. Kana kudzivirira mvura kuchidiwa, PET kana PP zvinhu zvinogona kushandiswa. Zvinyorwa uye pateni kudhinda zvinogona kupihwa.

2. Advertising & Poster

Smart maposta ndeimwe yemashandisirwo eNFC tekinoroji. Iyo inowedzera ma tag eNFC kune ekutanga mapepa kushambadzira kana zvikwangwani, kuitira kuti kana vanhu vaona kushambadzira, vagone kushandisa yavo yavo smartphone kutarisa iyo yakamisikidzwa tag kuti vawane ruzivo rwakakodzera rwekushambadzira. Mumunda wemaposta, tekinoroji yeNFC inogona kuwedzera mamwe kudyidzana. Semuyenzaniso, posita ine NFC chip inogona kubatanidzwa kune zvirimo zvakaita semimhanzi, mavhidhiyo, uye kunyange mitambo yekudyidzana, nokudaro ichikwezva vanhu vazhinji kuti vagare pamberi peiyo posita uye kuwedzera maratidziro emhando uye kusimudzira maitiro. Nekuzivikanwa kwema smartphones ane NFC mabasa, NFC smart posters anoshandiswawo mune mamwe minda.

Ruzivo rwuri muNDEF fomati senge maposta akangwara, mameseji, maURL, nhamba dzekufona, ekutanga maapplication, mepu anoronga, nezvimwe zvinogona kunyorwa muNFC label yeNFC-inogonesa zvishandiso kuverenga nekuwana. Uye ruzivo rwakanyorwa runogona kuvharirwa nekuvharwa kudzivirira shanduko dzine hutsinye nemamwe maapplication.

Kuongororwa kweKusarudzwa Kwechigadzirwa 

Chip: Zvinokurudzirwa kushandisa NXP NTAG21x series machipisi. Iwo chaiwo maficha anopihwa neNTAG21x akagadzirirwa kunatsiridza kusanganisa uye kurerukira mushandisi:

1) Kurumidza Kuverenga kushanda kunobvumira kutariswa kweakazara NDEF mameseji uchishandisa chete FAST_READ kuraira, nekudaro kuderedza nguva dzekuverenga munzvimbo dzekugadzira-vhoriyamu;

2) Kuvandudzwa kweRF kuita, ichipa kuchinjika kukuru muchimiro, saizi uye kusarudzwa kwezvinhu;

3) 75 μm IC ukobvu sarudzo inotsigira kugadzirwa kwema tag matete-tete kuti abatanidzwe zviri nyore mumagazini kana mapepa, nezvimwewo;

4)Ne144, 504 kana 888 bytes yenzvimbo inowanikwa yevashandisi, vashandisi vanogona kusarudza zvinoenderana nezvavanoda.

Antenna:NFC inoshanda pa13.56MHz, ichishandisa aluminium etching process coil antenna AL+PET+AL.

Glue:Nekuti inoshandiswa pamaposta uye chinhu chinonamirwa chakatsetseka, chinodhura chinopisa chinonyungudutsa glue kana mvura glue inogona kushandiswa.

Surface material: art bepa rinogona kushandiswa. Kana kudzivirira mvura kuchidiwa, PET kana PP zvinhu zvinogona kushandiswa. Zvinyorwa uye pateni kudhinda zvinogona kupihwa.

3. Anti-yekunyepedzera

NFC anti-counterfeiting tag ndeyemagetsi anti-counterfeiting tag, iyo inonyanya kushandiswa kuratidza huchokwadi hwezvigadzirwa, kuchengetedza zvigadzirwa zvekambani, kudzivirira zvigadzirwa zvemanyepo kuti zvisafambe mumusika, uye chengetedza kodzero dzevatengi nezvido. yevatengi.

Iyo yemagetsi anti-counterfeiting label yakanamirwa kune chigadzirwa kurongedza, uye vatengi vanogona kuona yemagetsi anti-yekunyepedzera label kuburikidza neAPP paNFC nhare mbozha, tarisa ruzivo rwechokwadi, uye kuverenga ruzivo rwechigadzirwa. Semuenzaniso: ruzivo rwemugadziri, zuva rekugadzira, kwaakabva, zvakatemwa, nezvimwe, decrypt iyo tag data uye uone huchokwadi hwechigadzirwa. Imwe yemabhenefiti eiyo NFC tekinoroji kuve nyore kwayo kusanganisa: madiki marebhu eNFC akareba mamirimita gumi uye anogona kuiswa zvisingaite mukutakura kwechigadzirwa, zvipfeko kana mabhodhoro ewaini.

Kuongororwa kweKusarudzwa Kwechigadzirwa

1.Chip: Zvinokurudzirwa kushandisa FM11NT021TT, inova tag chip yakagadzirwa neFudan Microelectronics inowirirana neISO/IEC14443-A protocol uye NFC Forum Type2 Tag standard uye ine yakavhurika yekuona basa. Inogona kushandiswa zvakanyanya muminda senge yakangwara kurongedza, chinhu anti-yekunyepedzera, uye kudzivirira kuba kwezvinhu.

Nezve kuchengetedzeka kweNFC tag chip pachayo:

1) Chip yega yega ine yakazvimirira 7-byte UID, uye iyo UID haigone kunyorwa patsva.

2) Iyo CC nzvimbo ine OTP basa uye inodzivirira kubvarura kudzivirira kuvhurika kwakashata.

3) Nzvimbo yekuchengetedza ine kuverenga-chete yekuvhara basa.

4) Iyo ine sarudzo inogonesa password-yakachengetedzwa kuchengetedza basa, uye iyo yakanyanya nhamba yekuyedza password inogadziriswa.

Mukupindura kune vanonyepedzera kudzokorodza ma tag uye kuzadza mabhodhoro echokwadi newaini yekunyepedzera, tinogona kugadzira NFC isina kusimba mavara ane tag chimiro dhizaini, chero pakavhurwa chigadzirwa, iyo teki ichatsemuka uye haigone kushandiswazve! Kana iyo tag ikabviswa, iyo tag ichatyorwa uye haigone kushandiswa kunyangwe ikabviswa.

2.Antenna: NFC inoshanda pa13.56MHz uye inoshandisa coil antenna. Kuti iite isina kusimba, chigadziko chepepa chinoshandiswa semutakuri weantenna uye chip AL+ Pepa+ AL.

3.Glue: Shandisa rinorema-release glue pabepa repasi, uye light-release glue kune yepamberi zvinhu. Nenzira iyi, kana tag yabviswa, zvinhu zvemberi uye bepa rekutsigira zvinoparadzanisa nekukuvadza antenna, zvichiita kuti NFC isashande.
