Which of the following is often cited as a disadvantage of biometric systems?

The cost of biometric devices is often considered a disadvantage of biometric systems. While biometrics offer high security and convenience, the initial investment required for the hardware, software, and infrastructure can be significant. This includes expenses related to the technology needed for capturing biometric data, such as fingerprint scanners, facial recognition cameras, or iris readers. Additionally, implementing and maintaining these systems can incur ongoing costs for updates, maintenance, and personnel training.

The economic barrier can limit the accessibility of biometric systems for smaller organizations or those with restricted budgets, potentially making them less appealing as a security option compared to traditional password or ID systems. As a consequence, while biometric systems may provide enhanced security and user experience, financial considerations can impede their widespread adoption.
