Ndi chidziwitso chamtundu wanji chomwe chingalembedwe mu NFC Tags

NFC (Near Field Communication) ndikusintha kwaukadaulo wa RFID; NFC imathandizira kulumikizana kotetezedwa opanda zingwe pakati pa zida ziwiri, ndikusinthana kogwirizana kwa data.
Ukadaulo wa NFC, womwe umayikidwa pa foni yam'manja kapena piritsi, umalola:
kusinthana kwa chidziwitso pakati pa zida ziwiri, zotetezeka kwathunthu komanso zachangu, pongoyandikira (kudzera pa Peer-to-peer);
kulipira mwachangu komanso kutetezedwa ndi mafoni am'manja (kudzera HCE);
kuwerenga kapena kulemba NFC Tags.
Kodi NFC Tags ndi chiyani
Ma tag a NFC ndi ma transponder a RFID omwe amagwira ntchito pa 13.56 MHz. Ndi tchipisi tating'onoting'ono (zozungulira zophatikizika) zolumikizidwa ndi mlongoti. Chip ili ndi ID yapadera komanso gawo la kukumbukira komwe kungathe kulembedwanso. Mlongoti amalola chip kuyanjana ndi wowerenga / sikani wa NFC, ngati foni yamakono ya NFC.
Mutha kulemba zambiri pamakumbukidwe omwe alipo a NFC Chip. Izi zitha kuwerengedwa mosavuta (ndi kuchitidwa) ndi chipangizo cha NFC, monga foni yam'manja kapena piritsi. Muyenera kungodinanso Tag ndi chipangizo chanu.
Onani mndandanda wa Ma Smartphone ndi Ma Tablet omwe ali ndi NFC
Kukula ndi mawonekedwe
Mtundu wodziwika kwambiri wa tag ya NFC ndi zomata, zomwe ndi chizindikiro chomwe chimakhala ndi dera ndi mlongoti. Chifukwa cha kukula kwawo kakang'ono, komabe, ma tag a NFC amatha kuphatikizidwa mosavuta ndi zothandizira zingapo, monga khadi, wristband, mphete yachinsinsi, gadget, ndi zina zotero. Chinthu chokhala ndi NFC Tag chikhoza kudziwika mwapadera chifukwa cha code yapadera. wa chip.
Magetsi
Chochititsa chidwi kwambiri cha ma tag a NFC ndikuti safuna mphamvu yachindunji, chifukwa imayendetsedwa mwachindunji ndi maginito a NFC sensor ya foni yam'manja kapena chipangizo chomwe chimawawerenga. Tag imatha kukhala yomatira ku chinthu kwa zaka zambiri ndikupitiliza kugwira ntchito popanda zovuta.
Memory
Kukumbukira komwe kulipo kwa ma tag a NFC kumasiyana malinga ndi mtundu wa chip, koma nthawi zambiri kumakhala kosakwana 1 kilobyte. Izi zitha kuwoneka ngati zolepheretsa, koma kwenikweni ma byte ochepa okha ndi okwanira kuti apeze ntchito zodabwitsa, chifukwa cha muyezo wa NDEF, mawonekedwe a data a NFC olembedwa ndi NFC Forum. Chimodzi mwazochita zofala kwambiri pakutsatsa, mwachitsanzo, ndikukonza ma URL omwe amatchula tsamba lawebusayiti. Tag, yokonzedwa kwambiri, imatha kugwiritsidwa ntchito pa chinthu chilichonse, kabuku, zowulutsira. Ndi ntchitoyi, iwo ali ofanana ndi QR Code, koma ali ndi mphamvu zambiri za deta, zomwe zimapangitsa kuti zikhale zothandiza pa nkhani ya malipoti ndi kusanthula kampeni. Kuphatikiza apo, amatha kusinthidwa ndi zithunzi zawo ndipo safuna, osachepera Android, pulogalamu iliyonse kuti iwerengedwe. Kuphatikiza apo, kukumbukira kwa NFC Tag kumagawidwa m'magulu angapo, omwe angagwiritsidwe ntchito popanga mapulogalamu ovuta kwambiri (zowerengera, khadi lachipatala, ndi zina).
ID yapadera
Ma tag onse a NFC ali ndi code yapadera, yotchedwa UID (ID Yapadera), yomwe ili patsamba loyamba la 2 la kukumbukira, lomwe latsekedwa (sangasinthidwe kapena kuchotsedwa). Kudzera mu UID, mutha kulunzanitsa Tag ya NFC ku chinthu kapena munthu, ndikupanga mapulogalamu omwe amawazindikiritsa ndikulumikizana nawo.
Ndi chidziwitso chamtundu wanji chomwe chingalembedwe pa NFC Tags?
Pa NFC Tag mutha kulemba mitundu yambiri yazidziwitso. Zina mwa izi ndi zachinsinsi:
yambitsani / zimitsani Wi-Fi
yambitsani / kuletsa Bluetooth
yambitsani / kuletsa GPS
tsegulani/tsekani pulogalamu
ndi zina zotero…
