  • Difficult to duplicate, offering high security.
  • Can store multiple fingerprints, allowing access to selected individuals.


  • Can be expensive compared to traditional locks.
  • May fail to recognize a fingerprint if the finger is dirty or injured.
  • Relies on power; backup options are essential.

2. Retina and Iris Scanners

Description and Operation: Scans the unique patterns of the user’s eye to grant access.


  • Extremely secure, as the eye’s pattern is complex and unique.
  • Non-contact, hygienic method of access.
  • Quick recognition process.


  • High cost makes it less accessible for the average consumer.
  • Can be affected by lighting conditions or eye wear.
  • Requires power and is more complex to maintain.

3. Voice Recognition Systems
