Ingabe I-RFID Blocking Wallets Ibalulekile?

Kuyini ukuvinjwa kwe-RFID?

Ubuchwepheshe be-Radio Frequency Identification (RFID) busebenzisa amandla asuka endaweni kazibuthe kagesi ukunika amandla i-chip encane ethumela umlayezo wokuphendula. Isibonelo, i-chip ye-RFID ekhadini lesikweletu iqukethe ulwazi oludingekayo ukuze kugunyazwe umsebenzi, futhi i-chip ye-RFID ekhadini lokufinyelela inekhodi yokuvula umnyango noma isistimu ekhawulelwe.

Izinto ezithile, ikakhulukazi izinsimbi eziqhubayo, zivimbela amagagasi kagesi ukuthi angadluli kuzo. Umphathi wekhadi (noma ngezinye izikhathi isikhwama sonke) se-RFID blocking wallet senziwa ngento engavumeli amaza omsakazo adlule.

Ngaleyo ndlela, i-chip ayiqali, futhi noma iqala, isignali yayo ayidluli esikhwameni. Okubalulekile ukuthi awukwazi ukufunda amakhadi e-RFID ngesikhwama sakho semali.

Kungani kufanele ikhadi lakho livinjwe?

Omaka be-RFID bangamadivayisi angenzi lutho azodlulisela ulwazi lwawo ngenjabulo kunoma ubani ozolalela. Kungase kuzwakale njengeresiphi yokuvikeleka okubi, kodwa omaka be-RFID abangaskenwa ezindaweni ezikude ngokuvamile abalayishwa ngolwazi olubucayi. Isibonelo, zisetshenziselwa ukulandelela i-inventory noma amaphakheji. Akusho lutho ukuthi ubani ofunda umlayezo ngoba akuyona imfihlo.

Ukukhathazeka ngamakhadi e-RFID kuyakhula njengoba ayanda amadivayisi okufunda e-NFC angena ezandleni zomphakathi jikelele. I-NFC (Near Field Communication) iwubuchwepheshe obufana kakhulu ne-RFID, umehluko omkhulu uwububanzi. Ama-chip e-NFC angakwazi ukufunda ububanzi ngamayintshi kuphela. I-NFC empeleni iwuhlobo olukhethekile lwe-RFID.

Lena yindlela amakhadi "okuswayipha ukuze ukhokhe" asebenza ngayo namatheminali okukhokha afakwe abafundi be-NFC. Uma i-smartphone yakho ikwazi ukukhokha ngaphandle kokuthinta, ingasetshenziswa nokufunda amakhadi e-NFC. Ngakho ummisa kanjani othile ekusebenziseni ifoni yakhe ukuze akopishe ikhadi lakho le-NFC?

Yilokhu kanye isikhwama se-RFID sokuvimbela okufanele sikuvimbe. Umbono wukuthi othile angavele abambe umfundi wakhe we-NFC eduze kwesikhwama sakho semali futhi akopishe ikhadi lakho. Ngemva kwalokho bangenza idivayisi iphindaphinde imininingwane ye-RFID ukuze ikhokhe.

Ingabe I-RFID Protected Wallets Iwufanele?

Akungabazeki ukuthi umqondo ongemuva kwamakhadi okuvimbela i-RFID uqinile. Ngo-2012, ukuboniswa kokuthi ifoni ye-Android ingakwazi kanjani ukweba imininingwane yekhadi lesikweletu ngaphandle kwentambo yashiya kungekho muntu ongabaza usongo. Inkinga iwukuthi, lezi zinhlobo zokuhlasela azibonakali zenzeke endle.

Kunengqondo ukuthi i-NFC skimming ingasetshenziswa ngokumelene nemigomo ethile yenani eliphezulu ephethe ulwazi olubalulekile, kodwa akufanelekile ukuhamba endaweni ephithizelayo entshontsha ulwazi lwekhadi lesikweletu kubantu ongabazi. Akukhona nje kuphela ukuthi kunengozi yangempela yokwenza lokhu kuphanga esidlangalaleni, kodwa futhi kulula kakhulu ukweba ulwazi lwekhadi lesikweletu usebenzisa i-malware noma amasu obugebengu bokweba imininingwane ebucayi.

Njengomnikazi wekhadi, uvikelekile futhi ekukhwabaniseni amakhadi esikweletu kubanikezeli bamakhadi, akekho noyedwa kubo, ngokwazi kwethu, odinga isikhwama se-RFID sokuvimbela ukuze afaneleke. Ngakho-ke, okungcono kakhulu, ungagwema ukuphazamiseka okuncane lapho izimali ezebiwe zishintshwa.

Uma ungumuntu onenani eliphezulu ohlosiwe, njengesisebenzi esinekhadi lokufinyelela ukuze ufinyelele impahla ebalulekile noma ebucayi, kuwukuhlakanipha ukusebenzisa i-RFID blocking case noma isikhwama semali.

Ngakho-ke, isikhwama se-RFID sokuvimbela siyakufanelekela ngoba lokhu kuhlasela okungenzeka okuncane kungasetshenziswa ngokumelene nawe. Kodwa asicabangi ukuthi lokhu kufanele kube yisici esinqumayo lapho ukhetha isikhwama sakho semali esilandelayo ngaphandle uma usengozini enkulu. Bese futhi, ama-wallet amahle kakhulu we-RFID blocking nawo angama-wallet amahle. Pho kungani kungenjalo?
