Abstract: This invention proposes a systematic approach to itinerant selling wherein a vendor-centric view is adopted for inventory control, authenticated access to loading and vending of retail items within local regulatory frameworks. By providing precise information of every item, location and time at which the item was sold, and quantity sold, this invention is able to maintain detailed transactional logs, which can be used later for establishing compliance and resolving disputes. By providing means to identify unique carts, assign unique codes for every action performed in the system and addressing operational difficulties such as need to relocate from congested places of business, this invention provides an end-to-end solution for authorized itinerant sales. Additionally, per-item analysis is available by using unique identifiers on the items and enabling location-determination of the cart and its inventory for maintaining appropriate checks and balances in the system.
