SmartTag ore tracking - Metso

SmartTag ore tracking

SmartTag ore tracking

All stages of a mining operation are influenced by ore characteristics. The SmartTag[TM] system tracks ore from the mine through the process, allowing ore characteristics to be correlated with important operating parameters in the mine and processing plant. These parameters can then be adjusted and optimized for different ore types to increase...

Useful Tips for Using RFID for IT Asset Management

Passive vs. Active RFID Comparison

The primary difference between passive and active RFID tags is that active tags are powered by a battery and automatically broadcast their signal, whereas passive tags do not have a power source and only transmit a signal upon receiving RF energy emitted from a reader in proximity of the tag.

RFID readers read RFID tags just like barcode scanners read...

RFID Asset Tracking - realassetmgt.com

RFID Asset Tracking

RAM's asset tracking software can be used in conjunction with RFID tags to help organizations protect and track their assets. Unlike barcodes, which have to be scanned individually within close sight of the scanner, RFID technology allows a batch of items to be identified as it moves past the scanning point or is scanned by a mobile reader. RAM provides quality-assured, customized RFID tags that are designed to suit your exact requirements. All RFID tags come with a guarantee. They are independently tested and can function in the toughest of environments.
