<prompt> Fingqa isihloko: Ikhadi le-SIM elasiza ekuguquleni umkhakha weselula ezinsukwini zokuqala zamafoni emoto amakhulu manje selisondela eminyakeni engu-25 likhona. Kodwa nakuba ama-SIM asetshenziswa kuwo aye athuthuka kakhulu phakathi naleso sikhathi, asabukeka ngendlela efanayo - nakuba emincane - futhi asafakwa ngaphakathi emishinini. Ochwepheshe bezesayensi yamakhompyutha baseCambridge bakholelwa ukuthi izinsuku zama-microchip amancane zibaliwe futhi kufanele singene kumafoni ethu ngendlela efanayo esifaka ngayo ama-akhawunti e-Internet. UDkt. Markus Kuhn waseYunivesithi yaseCambridge wathi i-SIM isithombe sesitoko yayingafakwa esikhundleni sayo kudala. Ukholelwa ukuthi ezinye izindlela zihlanganisa ukufaka i-ID yomsebenzisi nephasiwedi ngokuqondile ocingweni. Iqiniso liwukuthi i-SIM bekufanele ithathelwe indawo enye indlela elula: ukufaka i-ID yomsebenzisi nephasiwedi ngqo ocingweni kuyindlela - njengoba nje senza ukufinyelela i-WiFi, kusho uDkt Markus Kuhn wase-University of Cambridge. Noma amakhodi e-QR - amakhodi amamitha-ntathu ayisikwele - ayindlela elula kakhulu kuma-smartphone anamakhamera, lapho uhlelo lokusebenza lungafunda khona imininingwane efakwe ngekhodi ye-QR ngokuqondile ekhamera. UDkt. Kuhn waqhubeka: Amakhadi e-SIM ayisici esiwusizo lapho efika emakethe ngo-1991. Ngaleso sikhathi omakhalekhukhwini babeyimishini emikhulu, ngokuvamile efakwa ezimotweni futhi i-SIM yayizosiza amakhasimende ukuba adlulise ngokushesha futhi kalula inombolo yawo yocingo kanye noxhumana nabo esuka kolunye ucingo aye kolunye, ngaphandle kwesidingo sokuthayipha izihlonzi ezinde namakhodi okufinyelela ngaso sonke isikhathi. Ngenye indlela, amakhodi e-QR isibonelo esithombeni ayindlela elula yokugcina nokufinyelela idatha usebenzisa ikhamera ye-smartphone. Kodwa izinsuku zocingo olukhulu noma lwezimoto eziqashiwe sezidlulile, futhi namuhla ama-smartphone ayizinto ezilula, ezingokomuntu siqu esizinika amaphasiwedi amaningi amasayithi nezinsizakalo - ukufinyelela i-WiFi, i-e-mail, amanethiwekhi omphakathi, izitolo zezinhlelo zokusebenza, nokuthenga ku-inthanethi. Ukholelwa ukuthi ukushintsha ama-SIM ngamaphasiwedi noma isofthiwe eyengeziwe kungenza kube lula ukuba nezinkontileka eziningana zokukhokha-njengoba-usebenzisa ezivela kubahlinzeki abahlukahlukene ocingweni olulodwa. Bangase kamuva...  <response>: UDkt. Markus Kuhn wathi i-SIM kungenzeka ukuthi isishintshwe kudala. Ukholelwa ukuthi enye indlela kungaba ukuthayipha i-ID yomsebenzisi nephasiwedi ngqo ocingweni - njengoba senza ngamanethiwekhi e-Wi-Fi. Noma imininingwane ingase ifakwe amakhodi e-QR athathwe ngekhamera yocingo. Umfundisi waseYunivesithi yaseCambridge naye ukholelwa ukuthi sekuyisikhathi esifanele sokushintsha ngenxa yentuthuko yakamuva yezindlela zokubethela.
