1. Radio-Frequency Identification (RFID) :
It is an acronym for “radio-frequency identification” and refers to science whereby digital data encoded in RFID tags or smart labels are captured with aid of a reader by radio waves. In RFID data from a tag or label are captured via a gadget that stores data in a database. RFID, however, has quite a few benefits over systems that use barcode asset monitoring software. The most incredible is that RFID tag statistics can be examined outside line-of-sight.
An RFID tag incorporates a sensor connected to an antenna that allows transmission of data to reader. Each sensor carries a unique identifier and an RFID reader that can concurrently scan a lot of tags.
2. Barcode :
Barcode is a type of code which is machine-readable i.e. a machine-code/machine language in structure of numbers and a pattern of parallel lines of various widths, printed on a commodity and used specifically for stock control. Barcoding makes use of a scanner with a beam of light to “read” black and white traces of a barcode.
The scanner consists of a sensor that creates a signal from the mirrored or reflected light, and a decoder then interprets sign into textual content and sends it to a PC or database. Barcode scanners require line of sight and ought to “see” every barcode one at a time in order to seize data.
Difference between RFID and Barcode :
|1.||It is based totally on radio-frequency.||It is primarily based on optical technology.|
|2.||It does no longer require Line of sight.||It requires Line of sight because scanner must have an unobstructed view and must be oriented properly.|
|3.||It has greater data storage as in contrast to barcodes.||It has much less data storage up to solely 24 characters.|
|4.||Memory storage is possible in RFID with assist of tags.||Memory storage is not possible in barcodes.|
|5.||It is more resistant or durable than a barcode.||It is much less resistant than RFID.|
|6.||Several RFID tags can be examined simultaneously i.e. multiple read is allowed in RFID.||Only a single barcode can be scanned at a time i.e one card can be read at a time.|
|7.||Read/write abilities using RFID tags.||Barcode has totally reading capabilities and can’t write anything.|
|8.||It processes faster than Barcode.||It is slower than RFID.|
