Ikhadi le-RFID elikhuselayo lisebenzisa ibhodi yesekethe yomqondiso kunye nobuchwepheshe bokukhusela ukukhusela iimpawu ze-RFID. Sibeka ikhadi elikhuselayo eliphezulu kwi-wallet okanye ngaphakathi kwe-3cm yendawo apho sifuna ukukhusela isignali yekhadi elithile ukuze sifezekise umphumo wokukhusela umqondiso, kungakhathaliseki ukuba yintoni na isixhobo esisetyenziswa ngabaphuli-mthetho, abanakuba ikhadi lakho. ulwazi lokuqinisekisa ukuphatheka okukhuselekileyo kunye nokuthintela ukuvuza kolwazi. Ikhadi le-high-frequency shielding card liyakwazi ukunikezelwa kunye nezibane ze-LED kunye nezimbini ezingenazo izibane ze-LED, ezifana ne-LEDs: xa izigebengu zizisa izixhobo ezikhethekileyo zokweba ezikufutshane nawe, i-LED yekhadi elichasene nobusela liya kukhanya ukuze lisebenze njengesikhumbuzo.
