Project R

OneTap R1 is an intelligent attendance and tracking system designed to make presence real. Developed for schools and colleges, R1 combines advanced sensing, cloud connectivity, and AI-powered verification to close one of education's oldest loopholes — ensuring that when a student scans their card, they are physically present.

SFA 2.0

The Spatial Fusion Array is OneTap's proprietary spatial mapping system that observes and understands every student's entry in real time. As a student walks into the classroom, the SFA maps their presence and movement through the environment, generating verified spatial data unique to each moment.

Onetap R2 is the second-generation presence-verification system from Onetap Labs. It builds on the proven foundation of the Onetap R1 — the wall-mounted device that combines card-tap authentication with SFA 2.0 based body verification — and introduces automatic exit detection via TapID embedded in the student ID card.

SFA 2.0 refers to the second-generation Spatial Fusion Array — the multi-modal sensor architecture that powers Onetap R2. SFA 2.0 fuses three independent signals to produce attendance records that are more accurate, more honest, and less invasive than any camera-based system in the world

Presence. Verified. Without compromise.

Onetap Sentinel

The Spatial Fusion Array is OneTap's proprietary spatial mapping system that observes and understands every student's entry in real time. As a student walks into the classroom, the SFA maps their presence and movement through the environment, generating verified spatial data unique to each moment.

Onetap Sentinel is a variant of Onetap R2 designed for higher-education institutions that require a fully autonomous attendance verification system — one that operates without teacher participation, identifies students independently, and closes every loophole that a multi-modal sensor system can close.

Sentinel is engineered, manufactured, and supported by the same team that built Onetap R2 — the privacy-first attendance system trusted by institutions that chose the other path. Onetap respects that some institutions need autonomous verification, and others need camera-free verification. We build the right tool for each. We never confuse the two.

Autonomous attendance. For colleges that need it.
