DESC:FIELD OF INVENTION
[001] The invention relates to the field of shopping carts and more particularly to an ergonomic shopping cart integrated with weighing and billing facilities.

BACKGROUND
[002] Shopping carts are small vehicles for placing products and are designed to carry the products within a store, until the billing section. Though the shopping carts have simplified the task of carrying the products, the customers have to wait in the billing section, until their turn comes up in the billing queue. This results in longer waiting periods, which may dissuade customers from visiting physical stores for shopping.
[003] Most shopping carts are meant only for carrying products, but with changing lifestyles and health risks in crowded stores, some shopping carts have integrated features to avoid long billing and packing queues. However, some products which need to be weighed, require separate assistance from store personnel, where there may be additional queues and an increase in waiting period for the customer. These systems also are inconvenient and time-consuming for customers.
[004] Other systems use shopping carts which can identify the products based on identifying means, however these are error-prone, inefficient, require additional networking means and are time-consuming.
[005] Further there is required a connectivity between the warehouse of the products, the vendors, and shopping centers to understand customer demands, in order to meet the changing customer requirements.
[006] Prior arts in the field have come up with some modifications for these issues, and one such prior art disclose a kind of intelligent shopping trolley which comprises a shopping basket with cover plate, and a barcode scanning facility which additionally provides title and unit price based on the commodity generated.
[007] Other existing systems disclose an autonomous settlement shopping cart, comprising a shopping cart with multiple storage boxes independent of each other, where the opening and closing of the door of each storage box is controlled by a management system.
[008] Though the prior arts brought modifications in identifying products through RFID tags or barcodes, none of the prior arts discuss any other features to decrease the waiting period and improve the shopping experience of the customer.
[009] Thus, in light of the above discussion, it is implied that there is a need for a system with a cart based on ergonomic standards, with which the user can enjoy a hassle-free shopping, and which is free of the problems mentioned above.

OBJECT OF INVENTION
[0010] The principal object of this invention is to provide a shopping cart capable of weighing products, thereby eliminating the need for providing numerous weighing stations in a store.
[0011] Another object of the invention is to provide a shopping cart capable of displaying the billing amount for purchases of different products by a customer.
[0012] Another object of the invention is a shopping cart capable of providing payment options in the cart.
[0013] Another object of the invention is to capture and/or scan the products intended for purchase.
[0014] Another object of the invention is to initiate illumination for scanning the products, based on the proximity of the user.
[0015] Another object of the invention is to display the weight of the products in the displaying means, when the products are present on the weighing tray.
[0016] Another object of the invention is to provide a shopping cart based on ergonomic standards to use at ease with provisions for storing or hanging the bags for purchased products.
[0017] Another object of the invention is to provide a tray to place the products for weighing and scanning.
[0018] Another object of the invention is to reduce the waiting time, weighing machines, human intervention as well as store personnel required for weighing the products.
[0019] Another object of the invention is to provide a method of capturing and/or scanning, weighing, billing and initiating payment integrated, which is within the cart system.
[0020] Another object of the invention is to provide a system where the carts are integrated with software to identify the quantity of products sold or remaining in each category of products.
