A retail outlet has introduced radio frequency identification (RFID) tags to create unique serial numbers for all
products. Which of the following is the PRIMARY concern associated with this initiative?

A.
Issues of privacy

B.
Wavelength can be absorbed by the human body

C.
RFID tags may not be removable

D.
RFID eliminates line-of-sight reading

Explanation:
The purchaser of an item will not necessarily be aware of the presence of the tag. If a tagged item is paid for by
credit card, it would be possible to tie the unique ID of that item to the identity of the purchaser. Privacy
violations are a significant concern because RFID can carry unique identifier numbers. If desired it would be
possible for a firm to track individuals who purchase an item containing an RFID. Choices B and C are
concerns of less importance. Choice D is not a concern.
