Computerized methods useful for causing provision of user-specific services via one or more data network apparatus and user mobile device. In one embodiment, the method includes receiving user-specific location data (e.g., relating to a destination of travel or shipping desired by the user) from the user's mobile device via an electronic network proxy agent that acts as a proxy for multiple different users simultaneously, and automatically forwarding that received data to another computerized device to enable provision of the service relating to that user and location. In one variant, the user mobile device and the network proxy agent establish a secure session to facilitate transfer of the data to a network address or device specified in a secure user-specific account accessible to the proxy agent. In another variant, the mobile device interfaces with a kiosk at a point of departure to transfer the data.

A stacker device in an items processing system is a last station of a mail line. The stacker device has a receiving plate to receive flat items, a longitudinal alignment wall, graduated in at least two steps, at a rear side of the stacker device, and a stop wall that is arranged at the downstream end of the receiving plate.

Methods useful for processing shipping elements such as boxes, envelopes, and transport devices during transfer. In one embodiment, the shipping element contains an item being shipped by a user, and the method includes providing the user access to a computerized user interface by which at least information relating to the shipping element can be remotely obtained by the user. During at least one point during shipping, the shipping element is evaluated with respect to at least one physical parameter, and the user is informed via the user interface as to a status or condition of the at least one physical parameter. In another embodiment, a radio-frequency device is inserted into the shipping element along with a user item to be shipped, and the device is used as a basis for the remote provision of information relating to the shipping element during at least a portion of the shipping.

Methods, computer systems, and memory media for preparing instructions for printing a plurality of postage items. A graphical user interface (GUI) receives first user input. Responsive to the user input, an addressee data file is uploaded, features are extracted from a plurality of columns of the addressee data file, and the plurality of columns are associated with respective address field types based on the extracted features. The GUI displays an indication of the association between columns and address field types. User input may modify or correct the association. Responsive to second user input, instructions are prepared for printing entries from the columns of the addressee data file on respective postage items of the plurality of postage items as respective address fields, and the instructions are stored in a non-transitory computer-readable memory medium.
