RFID Smart Card

The RFID technology process starts with a tag, which is made up of a microchip with an antenna, and a reader with an antenna. The reader sends out radio-frequency waves that form a magnetic field when they join with the antenna on the RFID tag. A passive RFID tag creates power from this magnetic field and uses it to energize the circuits of the RFID chip. The chip in the radio frequency identification tag sends information back to the reader in the of radio-frequency waves. The RFID reader converts the new waves into digital information. Semi-passive RFID tags use a battery to run the circuits of the chip, but communicate by drawing power from the RFID reader.
Radio frequency identification or RFID is used in many different applications. Like other forms of automated identification, such as bar codes and scanning, it is very application specific. RFID has been used globally for over a decade and is a respected form of automatic identification. RFID systems share a common foundation: They utilize the electromagnetic wave spectrum to transfer data. Within the family of RFID solutions, there are many different types of technologies, which lend themselves to specific applications, such as retail, security, supply chain, and other valuable application areas.
