How do electronic tags and wearable readers help get the job done? If an engineer were to make a mistake operating city gas equipment, the results might be disastrous. This is why various measures are taken to ensure proper handling and repair. But even the most experienced engineer can make mistakes. Enter the Smart Assistant System. With this system, an electronic tag is embedded in the equipment. A wearable reader in the engineer's uniform then allows remote assistance and monitoring to prevent mistakes. And if tags were embedded in medicine cabinets in a pharmacy, rudimentary mistakes could be prevented during medicine preparation. At home, if you followed cooking preparations stored, for example, in tags in your ingredients box, you could prepare dishes like a professional chef.
