Kodi mafoni am'manja afanane ndi makhadi a RFID?

A: "Sindingathe kusinthana ndi kadi yanga"

B: "Kodi zapita ku maginito?"

Ndikhulupirira kuti aliyense amamva zokambirana zamtunduwu nthawi zambiri nthawi zambiri amagwiritsa ntchito makadi awo pamoyo wawo watsiku ndi tsiku, koma ndichifukwa choti kadi yanu ya mabasi ndi "yochokera ku maginito" yomwe simungasinthire?

 

Inde sichoncho. Masiku ano, makhadi osagwirizana ndi mabasi (kuphatikizapo koma osakhala ndi makhadi asukulu yazakudya, makadi opita ku kampani, makadi am'mudzi, ndi zina) zonse kugwiritsa ntchito ukadaulo wa RFID. Kodi ukadaulo wa rfid ndi chiyani? Mfundo yofunika kwambiri yaukadaulo ya RFID: Chitoliro cha RFID mukamatulutsa maginito ena, amalandira chizindikiro cha RF omwe amatanthauzira kuti atumizidwe pazomwe zimasungidwa mu chip, Wotanthauzira akamawerenga ndikupanga chidziwitsocho, chimatumizidwa ku dongosolo lazomwe limakhala ndi chidziwitso chogwiritsira ntchito deta.

 

Mwachidule, pamene khadi m'manja mwanu muli gawo la owerenga makadi, owerenga khadiyo kuti alandire magetsi, kenako ndikulola kuti mupeze madikodi a kadi (nthawi zambiri amakonzanso khadi ya basi). Chifukwa chiyani anthu ambiri amaganiza kuti makhadi a basi sangawerenge chifukwa alibe maginito? Anthu ambiri amadziwa kuti makadi a banki sangathe kuyikidwa pamodzi ndi mafoni ndi zinthu zamatsenga (chifukwa cha makhadi osiyana a Banki poyerekeza ndi maginito a magnet, ndipo makhadi a banki amasunga chidziwitso cha khadi). Mwina anthu amakhulupirira kuti makadi a RFID sangayikidwe limodzi ndi mafoni am'makalata, chifukwa chake makadi a RFID sangathe kuwerengedwa nthawi zambiri chifukwa amaikidwa pafupi ndi zinthu zachitsulo monga zipolowe za zipolowe. Ngati khadi siliwonongeka, imatha kuwerengedwa potenga khadiyo payokha.

 

Kuchita kwa makadi a NFC Battery sikugwirizana mwachindunji ndi maginito a foni palokha kapena malo ozungulira. Kuyesera kunawonetsa kuti ma tagi angapo adayikidwa mu 1.5t mphamvu ya magnetic kwa mphindi 5, mphindi 10, mphindi 1, ndi ola limodzi motsatana. Zinapezeka kuti coil inali ndi mphamvu yotentha, koma tag ya RFID ikhoza kuwerengedwa 100%. Chifukwa chake, kuyika makhadi a RFID (ma tags) ndi mafoni am'manja pamodzi sikungakhudzidwe ndi makina otsutsa.

 

Ma coils amkati ndi tchipisi a makhadi a RFID ali ngati nfc ntchito yomwe idapangidwa ndi mitundu ingapo. M'malo mwake, ntchito ya NFC ndikusintha paukadaulo wa RFID. Chip cha NFC chimaphatikizidwa mkati mwa foni, yomwe imatha kupeza ndikusinthana chidziwitso pakati pa foni ndi madera ena.
