# Product terminology

**Account number** — Operator-defined stable reference displayed alongside a subscriber and usable in search/import/payment context.

**Active session** — A RADIUS accounting session currently considered open. It is separate from account active/paused/blocked state.

**Binding** — Router-scoped MAC/device association with a reserved IP, managed through the Hotspot access path.

**Captive portal** — Hotspot web experience for package purchase, login, voucher/receipt use, trial, support, and terms.

**Collection** — Qualifying customer money received through a managed wallet flow; not every payment method funds a wallet.

**Disbursement / payout** — Movement of funds from one account/context to an external recipient through a supported provider.

**FUP** — Fair Usage Policy; a rule/alert/override related to consumption thresholds or service policy.

**Gateway** — Configured external/manual method for payments, SMS, email, or WhatsApp.

**MikroTik** — RouterOS-based network device commonly provisioned as a NAS in Centipid Billing.

**NAS** — Network Access Server; the router/device handling subscriber authentication/accounting/access services.

**PPPoE** — Point-to-Point Protocol over Ethernet; credential-based fixed-line subscriber access.

**RADIUS** — Authentication, authorization, and accounting protocol connecting subscriber credentials/policy to network sessions.

**Settlement** — External provider/bank completion of money movement, which can differ in timing from an application ledger update.

**Subscriber** — ISP customer/access account managed as Hotspot, PPPoE, or Binding.

**ISP account (workspace)** — Isolated workspace with its own subscribers, settings, network, billing, and branding.

**Voucher** — Bearer code granting the entitlement of a Hotspot package when valid and redeemed.
