In many large airports, biometrics is used in the form of iris scanners. Users must create an account and get their iris scanned to connect them to the account. Their details are then stored in an international database. As a result, users can walk into a booth and get their iris scanned instead of waiting in long passport queues.

Fingerprint scanners are used in high-security facilities to let only authorized personal entry.

Cars all use voice recognition when using Bluetooth and other entertainment systems. Some cars also use biometrics to unlock the doors.

In blood banks, it is important to preserve the identity of donors. In the past, this was done by issuing blue cards that contained all the information the donors required. It is now possible for donors to access their vital information using fingerprint or iris recognition.

In schools, biometric data is used for checking out library books and paying for meals. It is also used to ensure that only pupils and authorized adults gain entry to school buildings.
