RFID is increasingly a viable and cost-effective technology for the food industry. The high cost of items, their perishable nature, and the food safety needs for traceability are driving widespread adoption.
About RFID Technology:
RFID is an automatic identification technology, used for reliable and high-speed data capture.
Systems consists of readers, antennas, tags, and application software.
- RFID Tags are application specific, and second generation tags (“Gen2”) are small, reliable, and cost-effective.
- The food industry most commonly uses “passive” tags, which do not require a battery.
- Tags can be extremely durable for harsh environments, and optimized to work in and around metal (eg: stainless steel totes or aluminum trolleys)
- Tags are often combined with human-readable codes for redundancy
- RFID Readers, such as the Motorola FX9500 provide the intelligence to query tags and quickly retrieve the data that is recorded on them
- Mobile readers such as the Motorola MC9190Z and MC3190Z allow operators to point at tags to quickly read them
- RFID Antennas are application specific also, and are optimized to work in harsh environments, and to reliably target the RFID tags
- Software such as Carlisle Technology’s Symphony Plant Productivity and Traceability Suite matches the unique RFID identification number, and matches it against specific animals, bins of product, cartons, pallets, to extend traceability throughout the plant process.
How it works:
- Radio waves are sent from the RFID reader through antenna
- These Radio waves energize any RFID tags within range (the antennas are optimized to only target a desired area)
- The RFID tag reflects radio waves, adding its pre-programmed data to be sent to the RFID reader
