The Radio-frequency identification (RFID) technology uses radio waves to identify, trace & track and authenticate individual objects as they move between physical locations. There are different methods for identifying objects with RFID, the most common is by storing a unique number that identifies a product and related information. RFID devices and software must be supported by an architecture that enables the collection and distribution of location-based information in real time.
Information in RFID systems is transferred by means of radio waves much like a radio station, which broadcasts its programming on a short, medium or long wave frequency. These same frequencies, which are also used to transport data in RFID systems, are as follows: low frequency (LF): 125 megahertz; high frequency: (HF) 13.56 megahertz; and ultra high frequency (UHF): 860 to 960 megahertz.
The radio frequency that is applied in any given RFID system depends on the following factors:
1. The required read range.
2. The required item read speed.
3. The type of product being read.
4. The quantity of products being read.
5. The country in which reading is performed.
Features Of Radio Frequiencies
Like barcode technology, RFID technology allows for the interchange of product data by means of radio waves.
1. RFID is an extremely reliable and robust technology that is unfazed by adverse environments.
2. No line-of-sight contact is needed between the printer, reader and RFID tag.
3. The data from multiple data media can be captured and read via a single reading process (bulk data acquisition).
4. Makes data acquisition a more automated process.
5. EPC allows for automatic identification of products, palettes and shipping containers.
6. EPC/RFID allow for the smooth and efficient cross-border management of information and product flows across industries.
7. Unaffected by dirt, dampness, and optical masking.
8. Long service life; virtually wear and tear-free
9. High data storage capacity
10. The use of passive and active RFID tags allows for read/write fields ranging from a few millimeters to several meters
11. Data can be edited and added, Reusable data media.
12. Cost efficient data acquisition with high granularity
