Modular bank note recycling device
A modular valuable media recycling device is presented. The valuable media recycling device includes a media infeed module, a validator module, an escrow module, a plurality of media feeder/stacking modules, and a plurality of cassette modules. When a module handles a valuable media item along a media transport path, the module's identifier and security information are passed as a message to a next module that is to handle the media item in a processing path for the media item. Each module independently validates the authenticity of the message received from a previous module. The number of media feeder/stacking modules and cassette modules are scalable based on the transaction terminal that the modular valuable media recycling device is integrated into.
