The biometric device that is least user accepted is the retina scan, where a system scans the blood-vessel pattern on the backside of the eyeball.
When using this device, an individual has to place their eye up to a device, and may require a puff of air to be blown into the eye.
The iris scan only needs for an individual to glance at a camera that could be placed above a door.

Among the given options, the LEAST user accepted biometric device would be Retina scan.
Retina scans are a type of biometric authentication technology that scans the blood vessels in the retina of the user's eyes to verify their identity. However, this type of biometric device is not commonly used in everyday applications due to its invasive nature, as it requires the user to place their eye close to the scanner, which can be uncomfortable for some people.
On the other hand, fingerprint scanners are widely used in various applications, including smartphones and laptops. They are user-friendly, quick to use, and have a high level of accuracy. Iris scanners are also widely accepted, especially in airports and other high-security areas, as they are non-invasive and provide a high level of accuracy.
Voice verification is also becoming increasingly popular, with many companies using it for customer service and support. It is easy to use and has a high level of accuracy, making it a popular choice among users.
In summary, Retina scan is the least user accepted biometric device among the given options, as it is invasive and uncomfortable for some users, and not widely used in everyday applications.
