An electronic device is provided. The electronic device is connected to an external power supply through an interface. The electronic device comprises a processing unit and an input unit. The input unit responds to a power off operation to generate a power off signal and sends the power off signal to the processing unit. The processing unit periodically checks whether the electronic device is disconnected from the external power supply after receiving the power off signal, and powers off the electronic device if the electronic device is disconnected from the external power supply.

Embodiments of the invention are directed to systems and methods for utilizing a cache to store historical transaction data. A predictive model may be trained to identify particular identifiers associated with historical data that is likely to be utilized on a particular date and/or within a particular time period. The historical data corresponding to these identifiers may be stored in a cache of the processing computer. Subsequently, an authorization request message may be received that includes an identifier. The processing computer may utilize the identifier to retrieve historical transaction data from the cache. The retrieved data may be utilized to perform any suitable operation. By predicting the data that will be needed to perform these operations, and preemptively store such data in a cache, the latency associated with subsequent processing may be reduced and the performance of the system as a whole improved.
