T\u00eb gjith\u00eb jemi m\u00ebsuar me nj\u00eb gj\u00eb si NFC n\u00eb smartphone. Dhe duket se gjith\u00e7ka \u00ebsht\u00eb e qart\u00eb p\u00ebr k\u00ebt\u00eb.<\/p>\n

Shum\u00eb nuk blejn\u00eb smartphone pa NFC, duke menduar se \u00ebsht\u00eb vet\u00ebm p\u00ebr blerje. Por ka shum\u00eb pyetje.<\/p>\n

Por e dinit se \u00e7far\u00eb mund t\u00eb b\u00ebj\u00eb kjo teknologji? \u00c7far\u00eb t\u00eb b\u00ebni n\u00ebse n\u00eb smartphone-n tuaj nuk ka NFC? Si ta p\u00ebrdorni \u00e7ipin n\u00eb iPhone jo vet\u00ebm p\u00ebr Apple Pay? Pse nuk funksionon, ve\u00e7an\u00ebrisht me kartat Mir?<\/p>\n

Dhe p\u00ebrmes tij mund t\u00eb ngarkoni pajisje...<\/p>\n

Sot do t'ju tregojm\u00eb si funksionon dhe do t\u00eb shqyrtojm\u00eb t\u00eb gjitha detajet. Dhe m\u00eb e r\u00ebnd\u00ebsishmja \u2014 pse \u00ebsht\u00eb kjo teknologji m\u00eb e n\u00ebnvler\u00ebsuar n\u00eb smartphone-n tuaj!<\/p>\n

Si funksionon NFC?<\/h4>\n

\nSigurisht q\u00eb e dini se NFC i referohet si Near Field Communication ose n\u00eb shqip \u2014 komunikimi n\u00eb distanc\u00eb t\u00eb af\u00ebrt.
\n<\/a><\/noindex>
\nPor kjo nuk \u00ebsht\u00eb nj\u00eb transferim i zakonsh\u00ebm i t\u00eb dh\u00ebnave p\u00ebrmes val\u00ebve radio. Ndryshe nga Wi-Fi dhe Bluetooth, NFC \u00ebsht\u00eb m\u00eb i zgjuar. N\u00eb thelb, ka induktim elektromagnetik. Kjo \u00ebsht\u00eb nj\u00eb gj\u00eb shum\u00eb interesante nga programi i shkoll\u00ebs, kujtoni.<\/p>\n

\"NFC:
\nIdeja \u00ebsht\u00eb q\u00eb merrni nj\u00eb drejtues, n\u00eb t\u00eb cilin nuk ka energji elektrike. Dhe e vendosni pran\u00eb nj\u00eb drejtuesi tjet\u00ebr, n\u00eb t\u00eb cilin ka energji elektrike. Dhe e dini \u00e7far\u00eb? N\u00eb drejtuesin e par\u00eb, ku nuk kishte energji elektrike, fillon t\u00eb rrjedh\u00eb energji!<\/p>\n

E mrekullueshme, apo jo?<\/p>\n

Kur ne m\u00ebsuam p\u00ebr t\u00eb p\u00ebr her\u00eb t\u00eb par\u00eb, menduam se kjo ishte e pamundur! Seriisht? Po, ju po shihni! Shkoni t\u00eb luani Counter Strike, djem.<\/p>\n

Pra, kur afroni smartphone-in tuaj pran\u00eb ndonj\u00eb etikete NFC pa energji, ajo fush\u00eb elektromagnetike e vog\u00ebl nga smartphone-i \u00ebsht\u00eb e mjaftueshme q\u00eb brenda etiket\u00ebs t\u00eb fillojn\u00eb elektronet dhe t\u00eb funksionojn\u00eb \u00e7ipat e brendsh\u00ebm.<\/p>\n

\"NFC:
\nAh, po. N\u00eb \u00e7do etiket\u00eb ka nj\u00eb \u00e7ip t\u00eb vog\u00ebl. P\u00ebr shembull, n\u00eb kartat bankare, \u00e7ipi aktivizon madje nj\u00eb version t\u00eb thjesht\u00eb t\u00eb Java-s. Si \u00ebsht\u00eb kjo?<\/p>\n

Ndoshta keni d\u00ebgjuar p\u00ebr shkurtimin RFID. Ajo u zhvillua rreth 30 vjet m\u00eb par\u00eb. Ekuivalenti i saj \u00ebsht\u00eb identifikimi me frekuenc\u00eb radio. N\u00eb thelb, \u00ebsht\u00eb e p\u00ebrshtatshme vet\u00ebm p\u00ebr identifikim. N\u00eb shum\u00eb qendra zyrash, kalimet akoma p\u00ebrdorin RFID.<\/p>\n

\"NFC:
\nK\u00ebshtu, NFC \u00ebsht\u00eb nj\u00eb deg\u00eb e avancuar e standardit RFID dhe lexon disa nga k\u00ebto etiketa. Por ndryshimi kryesor \u00ebsht\u00eb se NFC gjithashtu mund t\u00eb transferoj\u00eb t\u00eb dh\u00ebna, p\u00ebrfshir\u00eb ato t\u00eb enkriptuara.<\/p>\n

NFC funksionon n\u00eb frekuenc\u00ebn 13,56 MHz, e cila i lejon t\u00eb zhvilloj\u00eb nj\u00eb shpejt\u00ebsi t\u00eb mir\u00eb nga 106 deri n\u00eb 424 Kbit\/s. Pra, nj\u00eb skedar mp3 do ngarkohet p\u00ebr disa minuta, por vet\u00ebm n\u00eb distanc\u00eb deri n\u00eb 10 cm.<\/p>\n

Fizikisht, NFC \u00ebsht\u00eb nj\u00eb spirale e vog\u00ebl. P\u00ebr shembull, n\u00eb Pixel 4 \u00ebsht\u00eb e lidhur me kapakun dhe duket k\u00ebshtu.<\/p>\n

Dhe tani \u00ebsht\u00eb koha t\u00eb flasim p\u00ebr at\u00eb se \u00e7far\u00eb mund t\u00eb b\u00ebj\u00eb NFC?<\/p>\n

Funksionimi i k\u00ebsaj teknologjie dhe i atyre p\u00ebrkat\u00ebse, si RFID, \u00ebsht\u00eb i p\u00ebrshkruar n\u00eb standardin ISO 14443<\/strong>.

Por e r\u00ebnd\u00ebsishme \u00ebsht\u00eb kjo: NFC mund t\u00eb funksionoj\u00eb n\u00eb tre m\u00ebnyra:<\/p>\n

    \n
  1. Aktiv.<\/strong> Kur pajisja lexon ose shkruan t\u00eb dh\u00ebna nga nj\u00eb etik\u00eb ose kart\u00eb. Po ashtu, po, t\u00eb dh\u00ebnat n\u00eb etiketat NFC mund t\u00eb shkruhen.<\/li>\n
  2. Transferimi midis pajisjeve t\u00eb barabarta.<\/strong> Kjo ndodh kur lidhni kufjet pa tel me smartphone-in tuaj ose p\u00ebrdorni Android Beam \u2014 e mbani mend k\u00ebt\u00eb. Atje lidhja ndodhte p\u00ebrmes NFC, nd\u00ebrsa transferimi i skedarit tashm\u00eb po b\u00ebhej p\u00ebrmes Bluetooth.<\/li>\n
  3. Pasiv.<\/strong>\u00a0Kur pajisja jon\u00eb sjell veten si di\u00e7ka pasive: si nj\u00eb kart\u00eb pagese ose nj\u00eb bilet\u00eb.<\/li>\n<\/ol>\n

    \nPse \u00ebsht\u00eb NFC e nevojshme, n\u00ebse kemi Bluetooth dhe Wi-Fi, sepse ato kan\u00eb m\u00eb shpejt\u00ebsi dhe rreze m\u00eb t\u00eb madhe?<\/p>\n

    \"NFC:
