Kodi RFID blocking ndi chiyani?
Ukadaulo wa Radio Frequency Identification (RFID) umagwiritsa ntchito mphamvu zochokera pamalo opangira ma elekitiroma kuti ipangitse mphamvu kachipangizo kakang'ono kamene kamatumiza uthenga woyankha. Mwachitsanzo, chip cha RFID mu kirediti kadi chili ndi chidziwitso chofunikira kuti muvomereze kuchitapo kanthu, ndipo chip ya RFID mu khadi lofikira ili ndi code yotsegula chitseko kapena makina oletsedwa.
Zida zina, makamaka zitsulo zoyendetsa, zimalepheretsa mafunde a electromagnetic kudutsa. Chosungira makhadi (kapena nthawi zina chikwama chonse) cha chikwama chotchinga cha RFID chimapangidwa ndi zinthu zomwe sizimalola mafunde a wailesi kudutsa.
Mwanjira imeneyo, chip sichimayamba, ndipo ngakhale zitatero, chizindikiro chake sichidutsa mu chikwama. Chofunikira ndichakuti simungathe kuwerenga makhadi a RFID kudzera mu chikwama chanu.
Chifukwa chiyani khadi lanu liletsedwe?
Ma tag a RFID ndi zida zomwe zimatumiza uthenga wawo mosangalala kwa aliyense amene angamvetsere. Zitha kumveka ngati njira yopezera chitetezo chochepa, koma ma tag a RFID omwe amatha kusanthula patali nthawi zambiri sakhala ndi zidziwitso zachinsinsi. Mwachitsanzo, amagwiritsidwa ntchito kufufuza zinthu kapena phukusi. Zilibe kanthu amene awerenga uthengawo chifukwa sichinsinsi.
Nkhawa za makhadi a RFID zikukulirakulira pamene zida zowerengera za NFC zikuchulukirachulukira m'manja mwa anthu wamba. NFC (Near Field Communication) ndi ukadaulo wofanana kwambiri ndi RFID, kusiyana kwakukulu ndikusiyana. Tchipisi za NFC zimatha kuwerenga mainchesi okha. NFC kwenikweni ndi mtundu wapadera wa RFID.
Umu ndi momwe makhadi a "swipe to pay" amagwirira ntchito ndi malo olipira okhala ndi owerenga a NFC. Ngati foni yanu yam'manja imatha kulipira popanda kulumikizana, itha kugwiritsidwanso ntchito kuwerenga makhadi a NFC. Ndiye mumaletsa bwanji munthu kugwiritsa ntchito foni yake kukopera khadi lanu la NFC?
Izi ndi zomwe RFID blocking wallet imayenera kupewa. Lingaliro ndiloti wina angogwira owerenga NFC pafupi ndi chikwama chanu ndikutengera khadi lanu. Kenako atha kukhala ndi chipangizocho kuti chifanizire zambiri za RFID kuti alipire.
Kodi Ma Wallet Otetezedwa a RFID Ndiwofunika?
Palibe kukayika kuti lingaliro lakumbuyo kwa RFID kutsekereza makhadi ndilolimba. Mu 2012, chionetsero cha momwe foni ya Android ingabere zambiri za kirediti kadi popanda zingwe zidasiya aliyense kukayikira za chiwopsezocho. Vuto ndilakuti, ziwawa zotere sizimawoneka ngati zikuchitika kuthengo.
Ndizomveka kuti skimming ya NFC itha kugwiritsidwa ntchito motsutsana ndi zolinga zamtengo wapatali zonyamula zidziwitso zamtengo wapatali, koma sikoyenera kuyenda mozungulira malo ogulitsira omwe akubera zambiri za kirediti kadi kuchokera kwa anthu osawadziwa mwachisawawa. Sikuti pali chiwopsezo chenicheni chochita izi pagulu, komanso ndizosavuta kuba zambiri zama kirediti kadi pogwiritsa ntchito pulogalamu yaumbanda kapena njira zachinyengo.
Monga mwini makhadi, mumatetezedwanso ku chinyengo cha kirediti kadi kuchokera kwa omwe amapereka makhadi, palibe amene, malinga ndi kudziwa kwathu, amafuna chikwama chotchinga cha RFID kuti ayenerere. Chifukwa chake, chabwino, mutha kupewa kusokoneza pang'ono pamene ndalama zabedwa zasinthidwa.
Ngati ndinu chandamale chamtengo wapatali, monga ngati wogwira ntchito yemwe ali ndi khadi lofikira kuti apeze zinthu zamtengo wapatali kapena zovuta, ndi bwino kugwiritsa ntchito chikwama chotchinga cha RFID kapena chikwama.
Chifukwa chake, chikwama chotchinga cha RFID ndichofunika chifukwa kuwukira kocheperako kungagwiritsidwe ntchito motsutsana nanu. Koma sitikuganiza kuti ichi chiyenera kukhala chosankha posankha chikwama chanu chotsatira pokhapokha mutakhala pachiwopsezo chachikulu. Kenako, ma wallet abwino kwambiri a RFID ndi ma wallet abwino. Nanga n’cifukwa ciani?
