SLIDE 16 RFID Technology
Data management important to fulfill higher performance
- Inspired Brightwork to look at the RFID
technology
- RFID known by electronic cat lids, wildlife
tracking and monitoring livestock Water sector
- Sand-Cycle first application
- Many more possibilities revealing the
unknown black box of processes
