Rfid Based Shopping Trolley Project Report
RFID Based Shopping Trolley
SYNOPSIS:
The objective of this project is to improve the speed of purchase by using RFID. This project is designed to use the RFID based security system application in the shopping trolley. This project is used in shopping complex for purchase the products. In this project RFID card is used as security access for product. If the product is put in to the trolley means it will shows the amount and also the total amount. But in this project RFID card is used for accessing the products. So this project improves the security performance and also the speed.

chapter – i 1. INTRODUCTION:

RFID is the special type wireless card which has inbuilt the embedded chip along with loop antenna. The inbuilt embedded chip represents the 12 digit card number. RFID reader is the circuit which generates 125KHZ magnetic signal. This magnetic signal is transmitted by the loop antenna connected along with this circuit which is used to read the RFID card number. In this project RFID card is used as security access card. So each product has the individual RFID card which represents the product name. RFID reader is interfaced with microcontroller. Here the microcontroller is the flash type reprogrammable microcontroller in which we already programmed with card number. The microcontroller is interfaced with keypad.

This project is designed with ➢ RFID tag ➢ RFID reader ➢ Microcontroller ➢ Driver circuit ➢ Alarm ➢ Relay. 3. CIRCUIT DIAGRAM

1 HISTORY:

In 1946 Léon Theremin invented an espionage tool for the Soviet Union which retransmitted incident radio waves with audio information. Sound waves vibrated a diaphragm which slightly altered the shape of the resonator, which modulated the reflected radio frequency. Even though this device was a passive covert listening

    Quad & Savi in Agribusiness

    Quad is a company which leases and services the plastic containers which are used from industries to grocers to transport the products. They are facing some difficulties with them supply chain and following processes for each container. SAVI proposes some new technologies to facilitate this tracking and the inventory management. So in my opinion, if I were SAVI, I would like to position the tracking technology to companies like Quad as a value-adding. The SAVI’s technologies will come for the other companies more like an advantage to improve their efficiency. Such technologies offer the possibilities to manage better the visibility of physical goods, to increase the supply chain efficiency and to facilitate the inventory’s management. The RFID technology adds value not only to the product but also to the QUAD Company. By using such service, they will increase the productivity and improve their products but also reduce the spendof-time. It is really a value—adding service. SAVI offers different kind of RFID tags: active or passive. The active tags are an evolution of the passive tags. They have the ability to transmit their location and other information like the time spending at the same place. Moreover they can be monitored by readers not far from them. So with all these capacities, it could be a great choice for QUAD to invest on this evolution. It will provide them more flexibility, give them the capacity to better organize them inventory and to improve the inventory…

    RFID Chips

    Radio-frequency identification (RFID) chips are small radio-frequency electromagnetic fields that can be used in a product, animal, and humans to track location, transfer data, and to identify the object. These chips are as small as a grain of rice and can store over 2,000 bytes of data. Some chips are powered by and read at short ranges via magnetic fields (electromagnetic induction). Certain chips use a local power source like a battery and some others that don’t use a local battery get the energy from interrogating electromagnetic fields and then act as a passive transponder to emit microwaves. RFID chips have been around for a very long time, but a lot of people don’t know what they are used for and what they are used in.…

    Rfid Tags

    Over time, the ways products have been tracked through the supply chain have changed just as technology is constantly progressing. Yet, there are still constraints to improve the methods of tracking and shipping due to the lack of technology in these fields. Bar codes have helped but still need human interference. Many companies are starting to turn to radio frequency identification tags. RFID tags can help companies with tracking and shipment of any product and reduce time to improve customer satisfaction. (Wolff, 2001) Companies such as IBM who are producing the tags have started to think of ideas to revolutionize this plan. The RFID tags can help track products as they enter and leave warehouses, and can speed up the shipping process. They can be put into different products and even use them in such ways as at the grocery store instead of having cashiers and cash registers. (Wolff, 2001) The superstore, JC Penney, is interested in taking advancements with the RFID tags. These tags are programmable and cannot get damaged like barcodes can. In the 21st century, we are constantly moving forward with such innovations. The RFID tags are currently in use by some companies already, and being modified by others for their particular needs. These tags could open doors for many new inventions and help us progress into a faster-moving and progressing world.…

    INTRODUCTION: In June 2003 Wal-Mart first announced its plan to implement RFID technology in its supply chain by January 2005; this caught many of the suppliers unawares. Though the plans envisaged compliance from the top 100 suppliers, around 129 suppliers jumped into the fray, afraid of being left behind in the race. RFID technology was invented in 1969 and patented in 1973; after thirty long years WalMart has demanded its implementation. Expectations are high, unfortunately RFID technology is still in its infant stage.…
