Tragbare Werbeinhalts- und Schnittstellenvorrichtung

摘要

A portable promotional content and interface apparatus (200) comprises a housing (201) that houses a memory (203) and a control circuit (202). This memory comprises, at least in part, a hidden digital storage area (204). The memory stores encrypted digital end-user promotional content and the hidden digital storage area stores the corresponding encryption key(s). The control circuit operably couples to this memory and also to a computational-platform interface (206) (such as, but not limited to, a USB plug). So configured, the control circuit interfaces with an end user's computational platform (301) via this computational-platform interface. Via that connection, the control circuit then serves to confirm a pre-established right for the end user to experience the stored end-user promotional content and to use the encryption key(s) to facilitate the end user experiencing that digital end-user promotional content through the end-user computational platform upon confirming that pre-established right.
