Some event recently inspired me to duckduckgo political system in Vatican. And Vatican is elective monarchy. And most often elective monarchies gradually become inheritable monarchies. But Vatican for some reason kept their status for millennials. :) So I believe political reasons are somewhere in this direction for priests and their fortune. However there are also some theological reasons for this decision in church.
Some banks offered it. For their own customers. But not anymore. And I believe there was Yandex pay. (But comming from Russia you would probably wat to avoid that too)
