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.
A method for accessing readers by means of a system comprising:
A computer program product stored on a computer-readable media containing software for performing a method for accessing readers by means of a system comprising:
An article of manufacture comprising a computer usable medium having computer readable program code means embodied therein for causing accessing of readers, the computer readable program code means in said article of manufacture comprising computer readable program code means for causing a computer to effect the steps of a method for accessing readers by means of a system comprising:
A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for accessing of readers, said method steps comprising the steps of a method for accessing readers by means of a system comprising:
