-How does RFID work and differentiate with bar coding. Also what is the impact of RFID in B2B e-Commerce. Solution RFID stands for radio frequency identification tag associated with each products. The main difference between the working of RFID and Barcoding are as follows: RFID Working: In RFID method a tag is affixed to the products which is used to identify and track product via radio waves. These tags can store or carry upto 2,000 bytes of data. RFID technology has three parts namely the scanning antenna, a transceiver and a transponder. The transceiver comes with a decoder to interpret the data and the transponder comes with the pre-set with information.The scanning antenna is used to send a radio-frequency signal to the RFID tag. As the RFID tag is passed through the frequency field of the scanning antenna; it will be able to detect the activation signal and further will be able to transfer the information data it holds to be picked up by the scanning antenna. Bar Coding: A visual representation of data that is scanned and interpreted for information is called as barcodes. A certain code is present in each barcode which works as a tracking technology for products. It is usually represented as a sequence of lines or in other shapes. Barcodes initially were one dimensional and were based on the width and spaces between parallel lines but later they were developed as two-dimensional with many geometrical shapes used for bar-coding. The barcode technology can be scanned with the help of bar-code readers. Impact of RFID in B2B and E-Commerce are as follows: RFID has a great impact on the B2B and E-commerce business since the radio frequency codes can now be checked easily. RFID has playeda significant role in fostering a higher level of integration between the supply chain members..
