Abstract
The present invention allows program specific configuration of several physical or logical readers, or other I/O devices, by using a configuration tool and a reader access layer. In an example embodiment, a configuration tool allows, a specifying access rights and priority rights for each single reader in conjunction with each single program. A reader access layer communicates with each program directly, calls up the reader access list for the requesting program, checks the access rights and the priority order for the available readers and returns a response to the requesting program containing information for accessing the active reader with the highest available priority. It secures previously defined access rights and access priorities between readers and programs defined in the reader access list remain unchanged independently when new readers are added.
