Mobile Case with Cash & Card Storage
75 patents in this list
Updated:
Mobile phone cases with integrated storage face distinct engineering challenges around card security and accessibility. Current designs must maintain a thickness under 12mm while protecting cards from electromagnetic interference, preventing accidental ejection, and allowing quick access—all without compromising the phone's wireless charging capabilities or signal strength.
The fundamental challenge lies in balancing secure card retention with ease of access while maintaining the slim profile expected of modern phone cases.
This page brings together solutions from recent research—including spring-loaded retention mechanisms, removable storage modules, biometric security systems, and ejector mechanisms for card accessibility. These and other approaches focus on practical implementations that maintain protection while enabling convenient everyday use.
