What is a con of smart badges?

• A. They are inexpensive to implement
• B. They always ensure data accuracy
• C. They can be intrusive unless informed consent is given
• D. They completely eliminate privacy concerns

Answer: (C)

Smart badges raise privacy considerations because they collect data tied to people’s presence and actions. The main drawback is that this tracking can feel intrusive unless people are informed and give explicit consent. When consent is clearly obtained, it helps legitimize the data collection and reduce discomfort, but the possibility of intrusion remains a concern if consent is missing or unclear.

The other ideas aren’t about the privacy drawback itself: whether something is inexpensive to implement varies and isn’t the ethical or privacy issue; data accuracy can be imperfect in any sensor system, so “always accurate” isn’t realistic; and no system can completely eliminate privacy concerns—there will always be trade-offs and ongoing concerns about how data is used and protected.
