Final answer:
The main privacy concern of RFID systems is the potential for unauthorized access to personal information. Skimming is an example of a privacy concern where someone can gather personal information without consent. Mitigating privacy concerns can be done through encryption and access controls in RFID systems.
Step-by-step explanation:
One example of a privacy concern with RFID is skimming.
Skimming is the unauthorized reading of RFID tags, where someone could potentially gather personal information without the individual's knowledge or consent.
This can occur when an RFID reader is in close proximity to an individual's RFID tag, allowing the reader to capture information from the tag.
To mitigate privacy concerns, it is important to implement security measures such as encryption and access controls in RFID systems.
Encryption can protect the data stored on the RFID tags, making it more difficult for unauthorized individuals to access the information.
Access controls can limit who has the authority to read or write data to the RFID tags, reducing the risk of unauthorized access.
