RFID or radio frequency identification is a technology that presents and shares some similarities with the bar code id system. With RFID, either electromagnetic or electrostatic coupling within the RF part of the electromagnetic spectrum is used in order for signals to be transmitted. RFID system is made up of an antenna and a transceiver, reading radio frequencies and then transferring information to a kind of processing device, and a transponder, an integrated circuit that contains RF circuitry as well as the information that’s going to be transmitted.
An RFID system has a wide array of usage. A tag could carry info such the pet owner’s name as well as address or even complex instructions such as assembling a motorcycle. Even some car manufacturers make use of the RFID system for them to move cars through their assembly lines. The tags tell the computers what the next steps in the automated assembly are at every production stage.
However, there are still some differences that lie in between the RFID system and that of the bar code. RFID removes the need for reading within your line of sight; however, this mechanism is needed by the bar code system. And in comparison to the bard code system, RFID can do scanning at a greater distance. The absence of any physical contact in RFID would mean that the readers will no longer be required to undergo a wear and tear process and it also applies to those tags which are being used for both reading as well as writing data.
Apparently, operations won’t come to its halt when RFID system is used. Bear in mind that your existing operations don’t need to slow down in order to bear extra overhead with regards to having physical contact between a tag and a reader. Physical contact may be deemed impossible at certain times; however, it is not always the case. . In a situation wherein tagged items are being moved quickly on conveyor belts, the chances are high that the readers are going to fail when it comes to maintaining physical contact with items that are in motion and this can result in a tag being missed. If the RFID system be contact-based, it couldn’t have been satisfactorily applied in quite the number of applications, business-wise.
