Muri iki gihe isoko ryapiganwa, guhagarara neza ni ngombwa-kandi amakarita yicyuma atanga ubuhanga butagereranywa. Ikarita ikozwe mubyuma bidafite ingese cyangwa ibyuma byateye imbere, aya makarita ahuza ibintu byiza kandi biramba cyane, birenze kure ubundi buryo bwa plastiki busanzwe. Uburemere bwabo bwinshi kandi bwiza, kurangiza neza butanga igitekerezo cya mbere kitazibagirana, bigatuma biba byiza kubikarita yinguzanyo yo murwego rwohejuru, gahunda zabanyamuryango zidasanzwe, impano zamasosiyete, hamwe namakarita yubudahemuka.

Kurenga isura yabo itangaje, amakarita yicyuma arakora rwose, ashyigikira tekinoroji yo kwishura igezweho nka EMV chips, NFC itagira aho ihurira, ndetse na magstripes. Ubuhanga buhanitse bwo gukora butuma ibintu byoroha, harimo gushushanya laser, gushushanya bidasanzwe, hamwe no kwambara bidasanzwe nka matte, gloss, cyangwa guswera neza. Waba ushaka minimalist, isura igezweho cyangwa itatse, igishushanyo mbonera, amakarita yicyuma atanga ibicuruzwa bitagira iherezo.

Umutekano nizindi nyungu zingenzi. Ikarita y'ibyuma iragoye kwigana kandi irwanya kwambara, iremeza gukoresha igihe kirekire idacogora cyangwa ngo yangiritse. Bagaragaza umwihariko n'icyubahiro, bishimangira icyemezo cyawe cyo kwiza.

Kubucuruzi bushaka kuzamura ishusho yabo, amakarita yicyuma nigikoresho gikomeye. Basiga ibitekerezo birambye, biteza imbere ubudahemuka bwabakiriya, no kuvugana indashyikirwa. Hitamo amakarita yicyuma-aho kwinezeza bihura nudushya.
