The use of RFID (radio frequency identification) tags in a reusable container management solution can provide you with reliable container movement data. RFID tags communicate through radio waves to exchange data from an antenna embedded in a tag attached to an object and an RFID reader, for the purposes of asset identification and tracking.
However, some tags can provide much more information than the asset’s encoded identity. Certain types of RFID tag can provide valuable information about the conditions of the reusable as well. From changes in pressure to light intrusion, these tags ensure that sensitive or perishable goods are safe and fresh when they arrive at their destination.
Changes in Temperature
Some tags can read temperatures from -20 °C to 125 °C (-5 °F to 230 °F), and “beacon” if a temperature outside a defined “safe” range is detected, ensuring perishables remain viable. For example – more than 28,000 organ transplants are performed each year; keeping those organs safe and temperature-controlled as they are transported is critical.
Some tags are even cold-chain compliant, providing temperature monitoring at the carton and item level at temperatures as low as -24C.
Changes in Pressure
Designed to monitor pressure without the need for batteries or wires, some tags are ideal for use within sealed environments to communicate changes in internal pressure, such as in tires, pipe systems, and even pressured liquid- or gas-filled containers – critical to supporting pressure-sensitive asset- and process-management applications.
Vibrations and Shocks
Some tags can be programmed to transmit a signal when movement is detected – or, send a signal when a moving tag has stopped. These capabilities are ideal for high-value assets, sending an alert when an asset is being moved, to determine if the movement is planned or an unapproved intrusion.
The internal power source of an active RFID tag not only gives tags the power necessary to conduct diagnostic tests of their surroundings, but to announce an alert in the event of non-conformance, enabling managers to be far more proactive in resolving issues. RFID technology can provide much more value than a tracking service alone. With the intelligence gathered through active RFID, you can boost efficiency and savings, make clearer decisions based on asset visibility, and rapidly intervene in the event of non-conformance.
