Ngaba likhona ikhadi elikhuselayo okanye okufanayo ukuthintela oku kungenzeki?

Eli khadi likhadi le-RFID Signal blocking card.

Inokukhusela izixhobo zangaphandle ekufundeni ulwazi lwekhadi kunye nokuthintela isignali yokufunda ikhadi. Ikhadi lekhaka elisetyenziswayo ngoku liquka imathiriyeli yePVC kunye netshiphu yekhaka. Ukusuka ngaphandle, akukho kwahluka kumakhadi ethu esazisi asetyenziswa ngokuqhelekileyo kunye namakhadi e-IC. Akunakwenzeka ngokupheleleyo ukubona ukuba yikhadi elineteknoloji emnyama.

Sonke siyazi ukuba kukho -amakhadi aphindaphindwayo kunye{1}}amakhadi aphindaphindwayo aphezulu kusetyenziso lwethu lwemihla ngemihla, ngoko ke leliphi ikhadi elikhadi lekhaka, kwaye leliphi ibhendi yefrikhwensi?

Okwangoku, amakhadi akhuselweyo ngamakhadi akhusela amabhanti aphezulu-okuthetha ukuba, amakhadi akhusela i-13.56MHZ, angamakhadi{2}}efrikhwensi aphezulu. Amakhadi ebhanki kunye namakhadi e-IC esiwasebenzisa yonke imihla -amakhadi aphindaphindiweyo.

Ke kutheni ungakhuseli, ikhadi eliphantsi lokuphindaphinda? Kungenxa yokuba ekusetyenzisweni okwenyani, ikhadi elisezantsi{0}}lokuphindaphinda lilula ukulisebenzisa, kwaye bambalwa, kwaye libandakanya ulwazi olugciniweyo, olusetyenziswa kakhulu kwikhadi eliphezulu{1}}lokuphindaphinda. Ke ngoko, ikhadi lokukhusela lizalelwe ukukhusela i-frequency ephezulu.

Beka nje i-smart card kunye nekhadi elikhuselweyo kunye, kwaye uphawu olungenazingcingo lwekhadi lakho lokuhlawula luya kukhuseleka ngokufanelekileyo. Kungakhathaliseki ukuba basebenzise siphi isixhobo abaphuli-mthetho, abayi kukwazi ukuba iinkcukacha zekhadi lakho, baqinisekise ukuthwala ngokukhuselekileyo nokuthintela ukuvuza kolwazi.

Iifayile ezishisayo: ikhadi lokuvalela uphawu lwe-rfid, iTshayina, abavelisi, ababoneleli, umzi-mveliso, olungiselelweyo, ngexabiso eliphantsi, isampuli yasimahla
