Asset Tracking RFID Technologies

Passive RFID

RFID is a technology for tracking and identifications. Each RFID label or tag has an electronic chip or silicon that works with radio frequency to provide wireless tracking capability. Each chip contains a unique identification number. Data can be stored in the chip as well. These electronic chips are in the form of sticker labels.

Passive RFID significantly reduces this labor intensive process because in most cases it does not require line-of-sight, can read at distances up to 2 meters, and can read multiple tags simultaneously.

Semi-passive RFID

Semi-passive tags are similar to active tags. One major difference is that a battery is used to run the microchip's circuitry but not to communicate with the reader. Some semi-passive tags sleep until they are woken up by a signal from the reader, which conserves battery life.

Battery-assisted technology offers a best of both worlds combination between active and passive: the benefits of the standardized Gen2 platform. Read ranges are similar to active RFID technology.

Active RFID

Active RFID tag or transponder can be affixed to virtually any asset (laptops or notebooks, computers, peripherals, electronic equipment, pallets, inventory items, etc.) for effective, long-range asset protection and monitoring throughout the enterprise or supply chain.

Signal transmissions penetrate walls and obstructions, traveling up to 35 feet within a typical facility, with longer ranges possible in open spaces, such as warehouses and computer rooms. Multiple tags can be read simultaneously such that both the asset and its carrier can be identified in an automatic, hands-free manner. This also allows the asset to be linked to one or more owners, providing maximum security with greater freedom of movement.

A tamper feature is available which triggers the tag or label to transmit a beacon alarm signal upon removal. Asset tags are also available that automatically transmit on a preprogrammed timed interval to assist in the tracking and monitoring of tagged objects across broad areas.

RTLS

Real Time Locating Systems (RTLS) are electronic systems that are intended to locate small electronic devices on people or things at any time. Most RTLS operate in the license free frequency range 300-433.92 MHz and 2.45 GHz. Different from conventional RFID systems, the RFID-based RTLS provides both identification and location of tagged objects by using a wired network of fixed RFID readers or interrogators.
