RFID vs Barcode
Summary: Difference Between RFID and Barcode is that RFID is a standard, specifically a protocol, that defines how a network uses radio signals to communicate with a tag placed in or attached to an object, an animal, or a person. While Barcode or Bar Code is a way of representing data, it is the small image of lines in the form of bars and spaces used to identify or get information about a particular item, product etc.
RFID
RFID (radio frequency identification) is a standard, specifically a protocol, that defines how a network uses radio signals to communicate with a tag placed in or attached to an object, an animal, or a person. The tag consists of an antenna and a memory chip that contains the information to be transmitted via radio waves. Through an antenna, an RFID reader reads the radio signals and transfers the information to a computer or computing device. Readers can be handheld or embedded in an object such as a doorway or tollbooth.
Barcode
Barcode or Bar Code is a way of representing data, it is the small image of lines in the form of bars and spaces used to identify or get information about a particular item, product etc. Behind these bars and spaces there are numbers and other symbols that represents information about that item or product. A barcode typically includes five parts.
- Quite Zone.
- Start Characters.
- Data Characters.
- Stop Character.
- Another Quite Zone.
A bar code reader, also called a bar code scanner, is an optical reader that uses laser beams to read bar codes. A bar code is an identification code that consists either of a set of vertical lines and spaces of different widths or a two-dimensional pattern of dots, squares, and other images. The bar code represents data that identifies the manufacturer and the item. A newer type of bar code, called a 2-D bar code, can store much more data than the traditional linear bar code. Manufacturers print a bar code either on a product’s package or on a label that is affixed to a product.
