A portable time transfer device is provided to transfer accurate date/time to reader devices and, thus, the reader devices do not have to be connected to a source of accurate time. A host computing system is configured to synchronize the portable time transfer device to a network, GPS, or other source of precise (accurate) time. Once the portable time transfer device is synchronized to the accurate date/time by the host computing system, the portable time transfer device is ready to be used by reader devices or any other devices (e.g., laptops, etc.) which need to maintain accurate time regardless of the connectivity to a network or GPS.
