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).

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.

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.

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

• 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

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

Our future applications:

RFID Toll gate system
