What is Sui Kiosk?

Could you please clarify what SUI Kiosk is exactly? Is it a new type of cryptocurrency exchange, or perhaps a hardware device used for transactions? I'm curious about its features, functionality, and how it differs from other platforms in the cryptocurrency space. Additionally, is Sui Kiosk accessible to users worldwide, or are there any specific regions where it's more prevalent? I'm eager to learn more about this platform and its potential impact on the industry.
