Yes—Ingenico’s unattended terminals can run in offline mode for certain use‑cases. For low‑value, contactless‑only transactions the devices can authorize payments locally (offline) while still keeping an online connection for periodic settlement and higher‑value authorizations. Higher‑value or chip‑&‑PIN transactions require online verification, so the terminals are typically configured with both offline capability for quick, small purchases and online fallback for larger or more secure payments.
