Ipayipi lokubhoboza ipayipi lensimbi elinamandla aphezulu elisetshenziswa ekubhobozeni.Kuye ngendlela yokubhoboza kanye nenjongo yokubhoboza, amapayipi afika ngokuqina nobude obuhlukene, ubude obuvame kakhulu bungamamitha angu-3-10.Amapayipi okubhoboza ahlanganiswe ndawonye ngamunye ngamunye njengoba umshini wokubhola uqhubeka ujula etsheni.Ehlangene, amapayipi akha intambo yokubhoboza, enganwebeka amakhilomitha ambalwa phansi emhlabathini.

Ipayipi lokubhoboza ngalinye linezingxenye ezintathu ezishiselwe ndawonye, ingxenye emaphakathi nezingcezu ezimbili zokugcina.Ucezu lokugcina luqukethe intambo yowesilisa (“pin”) noma eyesifazane (“ibhokisi”), evumela ukuxhunywa kwamapayipi amabili okubhoboza.Yonke intambo yokubhoboza ingaphansi kwemithwalo ephezulu kakhulu ngesikhathi sokubhola, futhi intambo ihlale iyingxenye ebaluleke kakhulu epayipini ngalinye.Uma nganoma yisiphi isizathu intambo yesilisa neyesifazane ingalingani ncamashi enye nenye, intambo cishe iyogqashuka futhi uzolahlekelwa yiyo yonke intambo yakho yokubhoboza.
