RFID: The newest Technology

RFID is an all-encompassing manifestation for technologies that use radio waves to recognize people or objects automatically. After storing a serial number or other id data on the computer chip linked for an antenna, user can use a visitor to receive radio surf from the chip and convert the signal into digital information, that can be passed over to computers and be used of.

This technology finds its maximum utilization in payment systems, access control and property tracking. For example, the logistics industry often uses it in making out large cargos.

RF technology has a widespread use in many areas of electronics and technology such as television, radio, cellular phones, radar and computerized identification systems. RFID (Radio Frequency Identification) provides Automatic Identification of items by using car radio frequency signals. NFC sticker can be used in various applications like toll collection (electronic), railway car identification and tracking, intermodal container identification, property identification and tracking, item management for retail, health care and logistics applications national, access control, creature identification, fuel dispensing devotion programmes, automobile immobilizing and so forth.

Radio Frequency (RF) makes mention of electromagnetic waves with a wavelength that fit to use in radio communication. Categorized by their frequencies, radio waves are indicated in kilohertz, megahertz or gigahertz. Radio frequencies range from very low frequency (VLF), which has a range of 12 to 30 kHz, to extremely high frequency (EHF), which has a selection of 30 to 300 GHz.

RFID is the fittest and supple technology for programmed procedure due to its resilience. It offers benefits not available in other recognition technologies. RFID can function under various environmental situations and offers a high quality of data integrity. Additionally, since the technology is not easy to simulate, it offers advanced level of security.

Essentially RFID is not different from bar code. Bar code utilizes a reader and coded labels that are attached to a product, whereas RFID employs a reader and special RFID card that are linked to an item. To transmit information from the label to reader, Bar code utilizes optical signals but RFID uses RF signals for the same.
