VISION:

          To ensure that people are getting safe products and to enhance the quality of purchase by means of our product.

DESCRIPTION:

          Our main idea is to make sure that the customers are purchasing good quality products. Good quality products in the sense products which haven’t expired. Initially the products details along with expiry date are sent to cloud through RFID technology. The details of the product which are expired is frequently sent to the shopkeeper via push notifications. So that the shopkeeper will be able to replace the products in time. This is profitable for the shopkeeper as he/she will be able to replace the old products. In case the shopkeeper fails to replace the old product, the barcode reader which is modified to read the expiry date will show that the product is an expired one. This method helps customer to choose the products without any doubt of the quality and also helps the shopkeeper to maintain the stocks efficiently.

NODERED FLOW

In this we used a input data (procode) product code from barcode reader, which is sent to cloud(* the cloud node is not used in this flow diagram, as we planned to implement it later) The cloud already contains the expiry database of each products which then compares the product with unique id whether it exceeds the limit. The node(expcheck) is used for comparing the expiry date of a particular product which is stored in cloud with the input name, if the condition is true the node (prosafe) which is directly connected to a display which displays the text “the product is in good condition”. If it fails the node (proexp) which is connected to IBM push notification centre sends an alert text message to the customer mobiles or to the stock manager that “the product is expired”. The above node red flow is for demonstration only, future applications will be added later on.
