Abstract: A packaging machine (1) having at least one registration device is described, in particular a log-in device (13, 16) for checking the personnel-related access authorization. In order that a log-in procedure for gaining access to the packaging machine (1) is associated with the smallest possible expenditure of time and/or effort, at least one of the log-in devices (13, 16) includes a reading unit for wireless and/or contactless reception of transmitted information from wireless and/or contactless readable portable data storage media (12, 18), as well as an alternative input device for the wired input of information. A data storage medium is also disclosed.
