Usage recommendations

Place the terminal on a stable, level surface and ensure unobstructed NFC access for contactless transactions. Keep the device firmware and POS software up to date, monitor available storage to prevent performance degradation, and rely on eSIM provisioning for deployments where physical SIM management is impractical. For high-transaction environments, connect to a stable wired or strong cellular network and schedule periodic device checks to confirm peripheral connections and payment terminal certificates are valid.
