Barcode

1.Barcode readers require a direct line of sight to the printed barcode. 2.The range to read a barcode is much less, typically no more t h a n fifteen feet. 3.Not more expensive . 4.Barcodes have no read/write capability information can not added in barcode.

RFID

1.Do not require a direct line of sight . 2.RFID tags can be read a t much greater distances up to 300 feet. 3.RFID tags are typically more expensive 4.RFID tags, can be read/write information can be added

A basic RFID system consists of three components: An a nt e nna or coil A transceiver (with decoder) A transponder (RF tag) electronically programmed with unique information

ARDUINO UNO BOARD

RFID RC-522 • MF RC522 is a highly integrated read and write card chip applied to the 13.56MHz less communication. Launched by the NXP Company, it is a low-voltage, low-cost, and small-sized non card chip, a best choice for intelligent instrument and portable handheld devices.

• The MF RC522 uses advanced modulation and demodulation concept which fully presented in all types of 13.56MHz ive less communication methods and protocols

RFID TAGS • RFID tags contain at least three parts: 1. An integrated circuit that stores and processes information and that modulates and demodulates radio-frequency (RF) signals; 2. A means of collecting DC power from the incident reader signal; 3. and an antenna for receiving and transmitting the signal. • The tag information is stored in a non-volatile memory. The RFID tag includes either fixed or programmable logic for processing the transmission and sensor data, respectively.

There are two type of RFID tag: 1. Active RFID Tag –  Their own power source.  Reader can be much farther away and still get thesignal.  Limited life s p an s . 2. ive RFID Tag –  Do not require power source.  Smaller in size.  Unlimited life span.

ARDUINO BOARD • Arduino is an open source electronics prototyping platform based on flexible, easy-to-use hardware and software (called sketch). It is intended for artists, designers, hobbyists and anyone interested in creating interactive objects or environments. • Arduino UNO is a board based on ATmega328 microcontroller. It consists of 14 digital input/output pins, six analogue inputs, a USB connection for programming the on-board microcontroller, power jack, an ICSP header and a reset button. • It is operated with a 16MHz crystal oscillator and contains everything needed to the microcontroller.

CIRCUIT SCHEMATIC

RFID technology does not require line-of-sight reading.  RFID tags can hold more dat a t h a n bar codes.  RFID tag d a t a can be changed or added to as a tag es through specific operations  RFID tags are more effective in h a r s h environments  A large number of RFID tags can be read almost instantaneously 

RFIDs are easy to conceal or incorporate in other items. For example, in 2009 researchers a t Bristol University successfully glued RFID microtransponders to live ant s in order to study their behavior. Hitachi holds the record for the smallest RFID chip, a t 0.05mm × 0.05mm. This is 1/64th the size of the previous record holder.Manufacture is enabled by using the silicon-on-insulator (SOI) process. These dust-sized chips can store 38-digit numbers using 128bit (ROM).

Limitations • Global standardization • Temperature Exposure • As the card details are stored in the microcontroller, only a limited number of card details can be stored. • This can be increased by implementing a memory unit like EEPROM. • Corporate Espionage: – Identify Valuable Items to Steal – Monitor Changes in Inventory • Personal Privacy: – Leaking of personal information (prescriptions, brand of underwear, etc.). – Location privacy: Tracking the physical. • Skimming: Read your tag, make my own. • Swapping: Replace real tags with decoys. • The security can be increased by integrating other security measures like facial detection, finger print scanner etc.
