A transaction is detected on a terminal. A context for an association of items, bags, shelving, carts, and individuals present during the transaction is maintained from images captured during the transaction. Rules are processed to determine actions to process during the transaction and/or after the transaction based on reported transaction details, the context, and analytics derived from the images for the context. In an embodiment, at least one rule identifies an action that overrides an attendant intervention at the terminal, which would have been issued for a detected weight discrepancy by a scale of the terminal.
