Final answer:
A radio-frequency identification tag (RFID) is an example of soft technology.
Step-by-step explanation:
An example of soft technology is a radio-frequency identification tag (RFID). Unlike hard technology, which involves physical devices and hardware, soft technology refers to systems that are intangible and often software-based.
RFID tags use radio waves to automatically identify and track objects, making them a soft technology example.
A database system is an example of soft technology. Soft technology refers to systems and solutions including software and methodologies that address issues and help improve processes, management, and information flow.
A database system fits this description, as it is primarily a software system for storing, retrieving, and managing data. On the other hand, a bar-code scanner, an image sensor, and a radio-frequency identification (RFID) tag are examples of hard technology, meaning they are tangible, physical technological devices.
