Abstract: The stacking wheel has one or a plurality of first and second stacking-wheel disks which are disposed on an axle in a mutually concentric relationship and spaced apart in the axial direction. Distributed over their circumference, the stacking-wheel disks respectively have a plurality of sheet slots for receiving a sheet and are disposed in a mutually staggered relationship in a portion of the sheet slots. An azimuthal profile offset of the stacking-wheel disks has the effect that the sheet slots of the first stacking-wheel disk run ahead of or run behind the sheet slots of the second stacking-wheel disk. The sheet slots of the first and second stacking-wheel disks have at their radially inside end an azimuthal profile offset that is reduced or eliminated again up to the slot end of the sheet slots. This avoids damage to the stacked sheets.

Abstract: The invention relates to a method on a portable data carrier (10). In said method, a web server (62) of the data carrier (10) preferably receives command information from a terminal (100) connected to the data carrier (10), the command information relating to at least one CAT command (“Card Application Toolkit” command). The at least one CAT command is then executed by a CAT interpreter (64) of the data carrier (10). The command information is embedded in an HTTP command request message of an HTTP client (110) of the terminal (100), and the web server (62) extracts the embedded command information from the HTTP command request message before relaying it to the CAT interpreter (64) of the data carrier (10) for execution of the at least one CAT command. In this manner there is enabled a flexible and resource-saving interaction between the web server (62) and the CAT interpreter (64).
