The invention relates to a method for franking postal deliveries, according to which an operating unit (BE) is operated separately from a franking unit (FE). Said method is characterised in that the operating unit transmits a transaction request (B1) to an authorisation unit (BR), the latter (BR) determines an authorisation for a user of the operating unit (BE) by means of an authorisation profile and the transmitted transaction request is authenticated by the authorisation unit (BR) according to the determined authorisation. The authorisation unit (BR) converts the authenticated transaction request (B1) into a transaction job, which is transmitted (B3) to a franking unit (FE). The transaction job is processed (B4) in the franking unit (FE) and finally the result of the execution of the transaction job is dispatched (B5) by the franking unit. The invention also relates to a device that is particularly suitable for carrying out said method.
