Ingenico terminals are capable of processing offline payment transactions, but whether this feature is available depends on the configuration set by your payment processor or financial institution. In offline mode, the terminal temporarily stores the transaction data locally and processes it once the internet connection is restored. However, this functionality is not controlled directly from the terminal settings; it is determined by the banking application provided by your acquirer or financial institution. To enable offline payments, you will need to contact your acquirer or financial institution to confirm if they support this feature and to set it up accordingly.
