HOW does RFID work

RFID typically involves three essential components: (1) a card or planted chip (2) a reader that scans and absorbs the information on the card or chip (3) a database that makes sense of the uniquely identified information provided by the reader.

Please note: The industry standard configuration includes a firewall or similar protection between the reader and the data management system depicted above to assure adequate security and safeguards. RFID can be either active or passive and can operate on different radio frequencies.

For more details on the underlying specifications, consult the International Organization for Standards' specifications, such as 14443 and 15693.

RFID has multiple operating frequencies.

Low frequency is ~125 kHz.

• A read only technology that uses a unique, random serial number.
• Primary use for this frequency is physical access control.

High frequency is ~13.56 MHz.

• A read / write technology that uses a unique, random serial number.
• Users may write data to the card.
• Primary uses of this frequency today are mass transit and cashless vending.

Ultra-high frequency is ~2.5 GHz.

• The primary uses of this frequency are toll road tags and asset and pallet tracking.
