URI yatsopano idaperekedwa ndi omwe amapanga njira yolipirira yaulere yamagetsi ndipo angagwiritsidwe ntchito kuitana mapulogalamu kuti alipire, mofanana ndi momwe "mailto" URI imagwiritsidwira ntchito kuyimbira maimelo makasitomala. Mu "payto:" imathandizira kufotokozera mu ulalo mtundu wamalipiro, tsatanetsatane wa wolandila, kuchuluka kwa ndalama zomwe zatumizidwa ndi cholemba. Mwachitsanzo, "payto://iban/DE75512106001345126199?amount=EUR:200.0&message=hello". The "payto:" URI imakupatsani mwayi wolumikizana ndi zambiri za akaunti ("payto://iban/DE75512108001245126199"), ma ID aku banki ("payto://bic/SOGEDEFFXXX"), ma adilesi a bitcoin ("payto://bitcoin/12A1MyfXbW65678jCZEqofac5QEPQ β) ndi zizindikiritso zina.
