Privacy
Computerized authentication systems, such as key cards, raise privacy concerns, since they enable computer surveillance of each entry. Currently RFID cards and key fobs are becoming more and more popular due to its ease of use. Many modern households have installed digital locks that make use of key cards, in combination with biometric fingerprint and keypad PIN options.
Bar code technology is not a secure form of a key, as the bar code can be copied in a photocopier and often read by the optical reader.

Famous quotes containing the word privacy:
“There is a privacy I love in this snowy night.
Driving around, I will waste more time.”
—Robert Bly (b. 1926)
“You may well ask how I expect to assert my privacy by resorting to the outrageous publicity of being one’s actual self on paper. There’s a possibility of it working if one chooses the terms, to wit: outshouting image-gimmick America through a quietly desperate search for self.”
—Kate Millett (b. 1934)
