POS knew what sold, never who bought it

SeumTech supplies POS and store-management software to hundreds of supermarket chains nationwide. The system knew exactly what sold, but nothing about who bought it. Customer mix was visible only for membership holders, and there was no evidence that the checkout screen carried any ad value.

An anonymous mix estimated on-device at the moment of payment

SpaceVision installed ScreenVision at supermarket checkouts. On-site devices estimate an anonymous age band and gender at the moment of payment for each transaction, building a continuous buyer-mix record without storing any face. Video is processed inside the on-site device and erased immediately; only anonymous aggregates leave the store.

Customers outside the membership came into the data

Every transaction now carries an anonymous buyer mix, and 99.9% of demographic data is captured at the moment of payment. With more than ten months of continuous buyer-mix data behind it, SeumTech can give retail clients transaction and buyer data as one combined view.
