Trisya is RFID Solutions based company. Our expert team has successfully completed more than 10 projects for a variety of industries and business domains in this technology. At least 30 million people carry an RFID tag on them every day in their car keys or in their access control card to get into their office building or to pay a toll. Radio-frequency identification uses electromagnetic fields to automatically identify and track tags attached to objects.
These tags contain electronically stored information. RFID tags are affixed to items in order to track them using an RFID reader and antenna. RFID tags transmit data about an item through radio waves to the antenna/reader combination. When the tag receives the transmission from the reader/antenna, the energy runs through the internal antenna to the tag's chip. These radio waves transmit data from the tag to a reader, which then transmits the information to an RFID computer program. RFID tags are frequently used for merchandise, but they can also be used to track books in library, students or employees in school, objects in organization and even Check-in Check-out of books in library. A tag can be read from up to several feet away and does not need to be within direct line-of-sight of the reader to be tracked.
When RFID chips are embedded in your ID cards, your bags, your possessions, you are effectively broadcasting who you are to anyone within range. To compete with barcodes, RFID chips need to be priced at under a penny each. The cost is gradually coming down, though. The data on the tags can be read by equipment from a few inches to several feet away -- and sometimes a bit farther. If someone wants access to the RFID data or the bar code data, it's essentially the same thing.
