RFID scanners are devices that can interrogate RFID tags to gather information, such as recognizing credit cards or locating products around the world. They work by sending out signals that RFID tags receive and respond to with additional data, like product details and a unique identification number. While useful for retailers, RFID scanners also raise privacy issues as their long range means tags may be read without a person's knowledge and could potentially be used to track locations.

Scanner and then returns the signal, usually with

unique number to the tag).

4. There are however privacy issues with these as
RFID tags are now so small that people don't
realise if they are still in the product.
Naturally, people are worried about personal
information being used against them, i.e. where
they live.
The scanners can work for up to 30 meters away
from the tag.

shops and credit cards for now.
