Snapfy identifies the invisible visitors who keep returning to the store and actually drive the business of the local store. A QSR operator can see sales but cannot track if customers are coming back for lunch. A supermarket can see basket size but cannot see whether its most loyal weekly shoppers quietly switched to the competitor across the street. Using edge AI processing, the Snapfy sensor distinguishes customers from employees, new visitors from returning ones, and individuals from groups, detecting people anonymously as random IDs. Snapfy presents real-time metrics including people counting, queue and flow analytics, and Returning Visitors.
