Assemblies, systems, and methods for applying postage indicia to one or more sequential mailpiece on a high speed mail sorter are disclosed. In some aspects, a system for franking one or more sequential mailpiece using a postal security device (PSD) hub assembly on a high speed mail sorter includes a plurality of PSDs configured to generate a coded digital signature for the one or more sequential mailpiece during a latency period, a plurality of photo sensors configured to define the latency period, a PSD host configured to receive the generated coded digital signature, wherein the generated coded digital signature is encoded in a data matrix, and an indicia printer configured to receive printer control data and to print the printer control data on the one or more sequential mailpiece in an order in which the plurality of PSDs are tasked during the latency period.

Provided is an unmanned mail/courier management system and method which can unmannedly receive a delivery of mail or a courier item, and can unmannedly store and receive a delivered mail or courier item. The system invention provides a configuration that enables a work, which is performed for unmanned reception and storage through interworking between an unmanned reception machine and a management server through a network in the art, to be input through and processed by a user terminal, and thus, does not require construction of a network for interworking with the management server in the unmanned reception machine for implementation thereof, thereby enabling easy installation of the unmanned reception machine, and minimizing a standby time by omitting a procedure of directly inputting in the unmanned reception machine.
