RFID stands for Radio Frequency Identification.
This technology allows for the electronic detection, tracking and control of items through production, warehousing and all forms of transportation.
How it works
An RFID tag is adhered to an item, carton or stillage.
Radio waves send energy via antenna to the tag which emits its own personal information or unique serial number back to the data collector/reader.
This information is transferred to the data management system by radio signals.
The data collected from the RFID tag is sent directly to the computer via standard interfaces or can be stored in a portable reader and up-loaded to the computer at a later date.

Integrated circuit chip attached to an antenna.
TYPES
- READ ONLY. Factory programmed memory with permanently stored information.
Has multiple read capabilities.
- PROGRAM ONCE MULTIPLE READ. User-programmable memory with multiple read capability.
Can only be programmed once.
- READ/WRITE. User-programmable memory with multiple read and write capability.
TAG POWER SOURCES
ACTIVE TAG. Battery power source with approximately 5 years life. Benefit - greater signal range. Drawback - they cost more.
PASSIVE TAG. Powered by RF energy. Benefits - smaller, lighter, cheaper with infinite life span. Drawback - signal range is much shorter.
TAG OPERATING FREQUENCES
- LOW FREQUENCY. 125kHz with a typical 100mm read range.
- HIGH FREQUENCY. 13.56MHz with a typical 0.3-1.0M read range.
- ULTRA HIGH FREQUENCY. 433-915MHz and 2.45GHz with a typical 1-3M read range under US FCC regulations.
