RFID is expanded as Radio Frequency Identification. It uses the wireless transmission and interpretation of electromagnetic fields for the purpose of identifying objects. RFID tags can be attached to virtually any object, be it a manufactured good or a vehicle or even a human being. The radio frequency emitted by any object that is paired with an RFID tag can be read using different types of scanners. Some types of scanners include, handheld, doorway and fixed scanners. Based on need, the scanners can be customised to suit the required purposes.
Our RFID services have prominent uses in
- Production follow-up and inventory.
- Manufacturing and asset tracking.
- Warehouse indexing.
- Poultry management with fowl weighing, vaccination and egg tracking.
- Zoo and veterinary clinic management with animal monitoring and tracking.
- Tracking the movements of patients and retrieving their medical histories in hospitals.
- Book management and handling in libraries.
- Car service stations to track the movement of the car through the station.
- Car parking management.
Being a relatively new technology, RFID works with the transmission of HF and UHF frequencies. In the case of the older barcode technology, each object has to be scanned individually and manually. The scanner has to have a direct line of sight to scan the barcode attached to the object. With a range restricted to a couple of inches, the barcode can be used only to read information. The attached stickers are unreliable and can be damaged/erased easily. They can also be tampered with. That is, they offer no protection.
RFID rises over all these shortcomings. RFID scanners can be automated without the use of man-power and can be used at ranges up to ten metres. Objects can be scanned in bulk at the rate of thousands of tags per second. Even if the objects are within containers or if the tags are blocked from view, RFID can still operate. The tags cannot be erased physically and can also be written to. The tags can be protected with a password to prevent unauthorized access.
Thus in a country like India, RFID is a technology that will revolutionise all fields and industries. There are two types of RFID available
- Active RFID
- Requires external power and has range up to 100m.
- Passive RFID
- Requires no power and has a range up to 10m.
With these extraordinary applications, RFID is an emerging technology that is changing the way identification and classification is handled. Universys is an early innovator in this growing technology, providing customised and targeted services to all areas of the market.
