Fashewar Shenhai-Hujja
Abubuwan cancanta don shigarwa, hidima, da kuma kula da na'urorin lantarki masu hana fashewa sun kasu kashi biyu: takaddun shaida na kamfani da takaddun shaida na mutum.
Ana sanya kowace takardar shaidar lambar takardar shaida ta musamman. Wannan lambar tana ba da damar tabbatar da halaccin takardar shedar ta hanyar dubawa tare da hukuma mai bayarwa.
