Eagle Eye AIR
Basic loyalty points and gift card ledgers are easy to build with AI assistance. However, Eagle Eye AIR is an enterprise engine handling sub-second promotion evaluation across thousands of physical POS terminals (e.g., NCR, Toshiba) alongside digital checkouts. Rebuilding the distributed infrastructure, high-throughput rules engine, and legacy hardware connectors is not feasible for a small team.
