Radio Frequency Identification (RFID) Technology
Efficiency. Accountability. Chain-of-Custody.
Organizations revolve around the people, information, items and processes that are required for the conduct of business. RFID is revolutionizing entire industries through the use of radio waves to tag, track, inventory and provide accountability of these objects and the business porcesses related to these objects.
Computers or bar codes require human-assisted identification and tracking one-at-a-time from a keyboard or from very close proximity. With radio waves, many objects at a time can be passively detected at precise locations or from distances up to 1,000’s of feet, without requiring human intervention. Knowing where objects are located at any moment and the status of those objects at all times improves operational efficiency, accountability and organizational performance.
RFID systems pay for themselves real-time by recovering more productivity than the investment in the technology, while also enhancing internal and external customer service.
Passive, Active and WiFi RFID Technologies
UHF RFID includes low-cost tags that are powered by radio waves generated by RFID fixed-position or portable scanners. UHF RFID is ideally suited for tracking item / people locations using chokepoint detection zones or through the use of portable scanners for inventories. UHF identifies the last known location of all items and people.
Active RFID utilizes more expensive, battery-powered tags that emit a signal that can be detected by choke-point detection zones or portable scanners. Detection zones can be calibrated for room level, close proximity or up to 1,000’s of feet. Whereas UHF RFID is ‘last location detected’, with Active RFID, the exact location of people and items is known at all times (real time location system).
WiFi RFID incorporates the most expensive tags, but, there is no requirement for RFID hardware for detection of items. WiFi tags send out signals that are detected by WiFi access points, providing real-time tracking of people and objects without installing detection infrastructure. WiFi can be complimented by room-level or location-specific optimizers.
