Barcode systems encode product information as parallel bars of varying widths that are scanned optically to facilitate faster logistics with less error. Benefits include improved customer service, data accuracy, reduced recalls, and monitoring of labor efficiency. Radio frequency identification (RFID) uses radio waves instead of barcodes to wirelessly transfer identity data of products or people, including location, price, and purchase date or personal information. An RFID system consists of tags with microchips and antennas to be read by scanners connected to a computer system.

2. Bar code system
The bar code system is an identification technology wherein there is
placement of computer-readable codes on items, cartoons and containers in
the form of grouping of parallel bars (usually blocks) of different widths
separated by light spaces (usually white),again, of different widths.
It facilitates speedier flow of logistical information such as product
identification, movement details, etc. with lesser probability of error.

4. Benefits of Bar code system
Improve customer service.
Enhance data accuracy.
Reduces product recall.
Speeds up data entry process.
Verifies orders at receiving and shipping.
Monitors labor efficiency.

5. R.F.I.D.
R.F.I.D. means radio frequency identification technology.
Automatic identification technology.
RFID uses radio waves to wirelessly transfer the identity of a
product or a person.
The purpose of RFID is to transfer data and provide information
regarding –
The location of a product, its price, its date of purchase.
Personal information.

6. RFID system consists of tags, readers and computer system.
Tags consist of computer microchip and an antenna. The antenna
helps scanners read the RFID tags.
