This document proposes a smart shopping system using RFID technology that can automatically generate bills. Key features include: 1) RFID antennas will detect items in a shopping basket and automatically generate a bill using RFID tags on each product. 2) The system supports both registered users with smart cards for payment from preloaded balances as well as non-registered users who must pay at checkout. 3) Product details like codes, names, prices are stored in a database and the system has features for modifying, deleting, and generating automatic bills from detected inventory.

- 2. Abstract: A Smart Shopping System has the feature of automatic billing when a customer carries a basketful of items through RFID antennas. The RFID antennas sense these items using multiple RFID Tag reader and generates the bill automatically. The RFID tags used on the items will be Ultra High Frequency(UHF).
- 3. Users can be registered or nonregistered. The registered user will be givena NFC card(Smart Card)which can be recharged by paying required amount in the same shop. If the customer is busy then he can just shop and shows his card for payment. Nonregistered users need to pay the cash at the counter when the bill is generated within few seconds.
- 4. Functional Requirements: Every product details such as Product-Code, P-Name, Price, Mf-date, Exp-date, UHFTAGID need to be stored in a database. Modifying product details. Deleting product details. Automatic bill generation facility. • Identifying registered customer using Smart Card and checking the balance on the card. If it is sufficient the bill amount should be automatically deducted from the card. Otherwise the customer need to be prompted for payment. • For nonregistered customers bill must be generated and the payment should be accepted by the system.
- 5. RFID Overview: Radio Frequency Identification (RFID):-It is a technology that uses radio-frequency waves to transfer data between a reader and a movable item to identify, categorize, track... RFID is fast, reliable, and does not require physical sight or contact between reader/scanner and the tagged item. • TAG: ATag is a transponder which receives a radio signal and in response to it sends out a radio signal. Tag contains an antenna, and a small chip that stores a small amount of data Tag is powered by the high power electromagnetic field generated by the antennas – usually in doorways .The field allows the chip/antenna to reflect back an extremely weak signal containing the data • Tags can be attached to almost anything: – pallets or cases of product – vehicles – company assets or personnel – items such as apparel, luggage, laundry – people, livestock, or pets – high value electronics such as computers, TVs, camcorders, cloths, Dresses
- 6. • READER:-An RFID reader is a device that is used to interrogate an RFID tag. The reader has an antenna that emits radio waves; the tag responds by sending back its data. The reader has two basic components – A scanning antenna ,A transceiver with a decoder to interpret the data • Readers (interrogators) can be at a fixed point such as – Entrance/exit – Point of sale – Warehouse • Readers can also be mobile -- tethered, hand-held, or wireless
- 7. Payment: • Automatic bill generated • Pre or post balance depositing in smart card • Bill can be paid by smart card/Shopping cards (Visa, master card, Debit/credit cards, charge cards) • swipe and pay
