I developed a printed circuit board (PCB) that operates using a Linux image with some applications running on a Micro SD card. What I am aiming to achieve is a method to ensure that the end user will not be able to read or access any of the data stored on the Micro SD card once it has been detached from the PCB. The goal is to secure the information and prevent unauthorized access or visibility of the stored content when the Micro SD card is removed.
