RFID Signal blocking Card

M'moyo wathu watsiku ndi tsiku, pali makhadi ambiri omwe amagwiritsidwa ntchito, kuwonjezera pa makhadi athu aku banki, pali ena, monga makhadi amembala, makhadi ogwiritsira ntchito, ma ID owongolera, makhadi a IC, ndi zina zambiri, onse amakhala mosawoneka Zimakhudza malo athu, ndipo takhala tizolowera kuzigwiritsa ntchito chifukwa ndizosavuta komanso zosavuta kugwiritsa ntchito. Ndiye pali zoopsa zina zomwe zikugwiritsidwa ntchito. Zigawenga zina zimapezerapo mwayi pazibowo kapena zofooka za makhadi ena kuti azibe kapena kukopera. Kodi pali khadi yotchinga kapena zina zotere kuti izi zisachitike?

Khadi ili ndi RFID Signal blocking card.

Ikhoza kuteteza zipangizo zakunja kuti zisamawerenge zambiri zamakhadi ndikuletsa chizindikiro chowerengera khadi. Khadi lachishango lomwe likugwiritsidwa ntchito pano limapangidwa makamaka ndi zinthu za PVC ndi chip chishango. Kunja, sikusiyana ndi makadi athu omwe amagwiritsidwa ntchito kwambiri ndi makadi a IC. Ndizosatheka kuwona kuti ndi khadi yokhala ndi ukadaulo wakuda.

Tonse tikudziwa kuti pali makadi otsika-makadi ocheperako komanso makadi{1}}afupipafupi omwe timagwiritsa ntchito tsiku ndi tsiku, ndiye khadi lotchinga ndi lotani, ndipo limakhala la mtundu wanji wa ma frequency?

Pakali pano, makadi otetezedwa ndi makhadi amene amateteza-ma frequency band, kutanthauza, makadi omwe amateteza 13.56MHZ, omwe ndi-makadi othamanga kwambiri. Makhadi aku banki ndi IC omwe timagwiritsa ntchito tsiku lililonse ali -makadi obwera pafupipafupi.

Ndiye bwanji osateteza, khadi yotsika pafupipafupi? Zili choncho chifukwa pakugwiritsa ntchito, khadi yotsika-ndi yosavuta kugwiritsa ntchito, ndipo ndi yochepa, ndipo imakhala ndi zinthu zina zosungidwa, zomwe zimagwiritsidwa ntchito kwambiri-makadi othamanga kwambiri. Chifukwa chake, khadi yoteteza imabadwa kuti iteteze pafupipafupi.

Ingoikani pamodzi khadi lanzeru ndi khadi lotetezedwa, ndipo chizindikiro chopanda zingwe cha khadi yanu yolipira chidzatetezedwa bwino. Ziribe kanthu kuti zigawenga zimagwiritsa ntchito chipangizo chotani, sadzatha kuba zidziwitso zamakhadi anu, kuonetsetsa kuti mukunyamula motetezeka komanso kupewa kutulutsa chidziwitso.
