The platform offers exclusive shopper analytics that map awareness, consideration, and conversion to help retailers optimize operations. Compared with competitors, AiFi provides end-to-end, configurable solutions across multiple formats (retrofitting, portable stores, and frictionless checkout) and emphasizes pure AI-driven visibility and analytics without relying on traditional hardware mixes.
