He aha nā pilikia o ka hana NFC RFID?

ʻO ka pilikia nui loa o ka hana NFC ʻaʻole pono ke kāleka e hoʻopā i ke kelepona paʻa ma lalo o ke kūlana o ka hālāwai ʻana i ka polokalamu a me ka lako. ʻOiai ka liʻiliʻi o ka mamao, hiki i ke kelepona paʻa ke heluhelu i ka ʻike ma ke kāleka ma ka makemake a hana i nā hana uku. ʻO ka hopena, ma nā wahi ākea e like me nā kaʻa kaʻa, nā subways, nā hale kūʻai kūʻai, a me nā mea ʻē aʻe, hiki ke ʻaihue ʻia ke kāleka i ke kāʻei a i ʻole ka ʻeke kālā e ka poʻe lawehala, a ʻaʻole e hōʻike wale nā ​​​​mea hoʻohana i ka ʻike pilikino, akā ua nalowale ke kālā he nui. .

ʻO ka hana o ka mea paʻa kāleka NFC RFID

Kāohi i ka ʻaihue ʻino i nā kāleka panakō, nā kāleka ID, nā kāleka kaʻa, a me nā mea ʻē aʻe. Kākoʻo ʻana i nā kāleka hana NFC e pale i ka palekana waiwai a me ka palekana ʻike pilikino; ua hoʻolālā ʻia e kūpono i nā kāleka panakō hou loa a nani a lokomaikaʻi. Hoʻolālā ʻia ka mea paʻa kāleka NFC e like me ke kumumanaʻo Faraday cage a hoʻohana i nā mea metala kūikawā e like me nā mea maka. Ua like ia me kahi "mea hana insulating". ʻOiai ka lōʻihi o ke kāleka i loko o ka mea paʻa kāleka, ʻaʻole hiki i kahi mea NFC ke heluhelu i ka ʻike kāleka, waiho wale ʻia. Hoʻouka hou, hoʻoili, uku a me nā hana ʻē aʻe.
