## Description

L-ink Card is a hardware implementation that combines an electronic ink display controller with an IC card emulator. The system utilizes the ISO 15693 protocol to enable wireless data exchange and energy harvesting from mobile devices, allowing the device to operate without a battery.

The project features a multi-identifier storage system and a physical selector switch to simulate various access cards and security tokens. It also supports the transfer of bitmap data from a companion mobile application to update the bistable e-ink screen with custom images, text, or digital business card profiles.

The hardware covers capabilities for non-volatile identity storage, passive power harvesting, and the rendering of graphics on electronic ink displays.
