All UniFi APs include Hotspot functionality:
Built-in support for billing integration using major credit cards.
Built-in support for voucher-based authentication.

Multi-Site Management
A single UniFi Controller running in the cloud can manage multiple sites: multiple, distributed deployments and multi-tenancy for managed service providers. Each site is logically separated and has its own configuration, maps, statistics, guest portal, and administrator read/write and read-only accounts.
