Your floor plan on the table: where sensors would go, what they would report there (entrance counts, capture rate, aisle and zone traffic, dwell, queue times), and what they would not. If you already run counters, bring last month's numbers and we will talk about why they disagree with the tills.

Ariadne measures this with Hybrid Fusion, its patented camera-free method. Time-of-Flight depth sensing counts every visitor at the entrances, capturing geometry rather than images, while patented phone signal sensing follows movement through the interior, detecting the signals a phone emits even in airplane mode, and tracks that movement to about one-metre precision. The sensor streams both feeds to Ariadne, where Hybrid Fusion combines them into one trajectory per visit and computes counts, dwell, and paths. The streams carry no identifier: no MAC address, no device ID, no biometric data, and no camera is involved. Identifiers are stored only when a visitor explicitly opts in, which keeps the method GDPR-friendly and outside biometric territory.

Nothing personal is captured at the sensor: no face, no demographic inference, no identifier. There is nothing to anonymise after the fact, and nothing for biometric privacy laws to attach to, which is a structural answer rather than a compliance project.

The measurement itself, the accuracy figures, and the comparison against camera-based counters live on the people counting page.
