RADIO FREQUENCY IDENTIFICATION (RFID) is the revolutionized bar code that we are currently using today. Although we are not aware how RFID works but it’s exactly the same as a bar code the differences are bar code can only scan one item at a time unlike for a RFID tags it can read/scan as many tags in one scanning. RFID tags has the capabilities of tracing where and when the item has been sold because it can read, store and update data. RFID tags are commonly use in tracking vehicles and airline passengers. Although RFID tags are more expensive compared to a bar code but eventually in the future, there would be a widely use of this RFIDs due to its ability to store and update data. Let’s see how these RFID tags will affect more of our lives in the years to come.
