How we think
Why the register, not the gate, is the point.
A gate is a moment. A register is what is left of it a year later, when someone asks who was here and who took a child home. Everything in the kit follows from that: the name comes from the chip, the identity from the hand, the roll call from the register itself.
What the register is for
A form, a lanyard, a glance. What the register is actually asked later, and why nothing should be typed.
Why palm vein
A card tells you what was handed in, never who handed it. A face is read whether you agreed or not. A hand is offered, and carries no photograph and no demographics.
When the alarm sounds
One question that must be answered with certainty: who is inside right now? The answer has to walk out of the building in someone's hand.
Who we are
The entire code is written by our own team, in low-level Rust with a thin layer of Kotlin. No code from any other source, no SDK, no website. Our own intellectual property, and the people who wrote it, by name.
