Difference between RFID and Barcode
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 :
| Sr.No. | RFID | Barcode |
|---|---|---|
| 1. | In RFID Radio Frequency (RF) technology is used. | In Barcode Optical (laser) technology is used. |
| 2. | It no longer requires 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. |
| 9 | Required power source | Power Source not Required |
| 10 | Data can be updated in real time | Data is read only cannot be changed. |
| 11 | Can scan from the item for its meter depending. | Required closure proximity for scanning. |
| 12 | Read time is less than 100 ms per tag. | Read time is half a sec or more. |
| 13 | RFID can be used in Harsher environment. | While in Barcode soiled labels are difficult to read. |
