Radio Frequency Identification, commonly known as RFID is a revolutionary technology which uses electromagnetic radio waves to read, store and capture information. When attached to an object, the user can track its movement whenever in transit. This technology has been used in several sectors to protect and keep a record of precious goods, products and machinery. With a consistent growth and elevation in technology, researchers of the world have able to combine NFC (Near Field Communication) technology with RFID. NFC is communication between compatible devices within a short range.
Compilation of NFC with RFID tags has enabled users to utilize features like Bluetooth pairing, device authentication, connection handover and Wi-Fi protected set up. NFC is actually a sub-category or a branch of RFID both of which operate at 13.56 MHz frequency.
RFID tags operate and function on three different frequency ranges.
1. Low Frequency (LF): 125-134 kHz tags
2. High Frequency (HF): 13.56mhz tag
3. Ultra High Frequency (UHF): 856 MHz to 960 MHz tags
The High Frequency 13.56mhz tag is eminently used in the logistics and transport sector so as to trace objects. It is a resourceful device that has NFC features with it. In healthcare sectors, these tags are useful in storing patient information, previous health records, medication prescribed and surgeries undergone (if any). These tags can be read from a considerable range and can be connected to gadgets like smart phones, tablets, laptops, etc. on which information can be read easily. Once the patient is discharged from the hospital, the tags are removed and destroyed.
Their range is about 5 inches and when connected with accordant readers, their range is up to 3 fts. RFID 13.56mhz tag are not used only in high power industries and organizations with high turnovers, it is also used in laundry identification. In the hospitality sector, where a large number of people come for a luxury stay, laundry service is provided to them for convenience. But it is difficult to identify that which cloth belongs to whom. RFID technology is an effective solution for it. The consolidation of NFC and RFID has undoubtedly fulfilled the identification and tracking needs of various industries and will continue to grow more in other sectors as well.
