There is provided a system for in-store consumer behaviour event metadata aggregation, data verification and the artificial intelligence analysis thereof for data interpretation and associated action triggering. The system may collect in-store consumer behaviour event metadata from a plurality of consumer electronic devices and then uses a trained artificial intelligence analytics engine to provide various artificial intelligence insights useful to such consumers which may further modify consumer behaviour. The trained artificial intelligence analytics engine may have a data interpretation controller configured for intelligently interpreting such aggregated in-store consumer behaviour event metadata and triggering actions accordingly which are then sent electronically to the consumer electronic devices. The data interpretation controller may have a data verification controller configured to optimise the data integrity of a consumer product metadata database representing a plurality of consumer products according to availability and other metadata.
