Ivyo bikoresho vyo kwumva vy’ugutwi birungikwa hanze cane cane mu bihugu n’uturere nka Leta Zunze Ubumwe za Amerika, Ubuholandi, na Tayilande, n’uruja n’uruza rw’ibintu vyinshi. Ico kigereranyo caco c’ugucuruza gishobora guhinduka ntigifasha gusa ubudandaji kugira ngo gishobore gushitsa ivyo abaguzi ku giti cabo bakeneye, ariko kandi buratanga ibikorwa vy’ubudandaji kugira ngo bishobore gufasha mu gukorana n’abandi mu bacuruza ibintu bitandukanye. Mu isoko mpuzamakungu, iki gikoresho co kwumva caratsinze ubuntu n’ugushemeza abakiriya benshi n’ibikorwa vyiza cane n’igikorwa c’agaciro kanini.
