Demo Video
After years of building and refining, here’s the BZCard finally working the way I always imagined it.
How It Works
-
On power-up, the BZCard displays a logo screen.
-
The main menu provides access to:
-
Contact Info
-
Social Media
-
Games (Snake, Brick Breaker, Tetris, Death Star)
-
Options/Settings
-
-
Capacitive touch buttons are used for navigation (up, down, left/enter, right/back, power).
-
After ~30 seconds of inactivity, the display powers down.
-
After ~120 seconds, the device enters deep sleep to save battery.
-
When connected to USB, a charging animation appears with a battery icon and progress effect.
-
Wake-up is possible by touching a button or pressing the power button.
-
The enclosure makes it possible to hold and showcase the card outside of a wallet, like a tiny handheld device.
