There are provided systems and methods for a network cache of device input for redundancy during device inoperability. A device may detect that the device is in danger of failure, for example, if a battery is low on the device, the device is damaged, or the device may lose network connectivity. On detection of such a condition, the device may request that a server that performs electronic transaction processing establish or trigger a mode that allows for caching of transaction data as input for the transaction data is entered to a device, which may be done by sending signaling to the server indicating the condition that affects the device's operability. The server may then cache input for the transaction data. If the device fails prior to approving and completing electronic transaction processing, the server may use the cached data to generate a digital ledger for another entity.
