What is a potential disadvantage of biometric-based systems?

Biometric-based systems, which rely on unique physical characteristics such as fingerprints, facial recognition, or iris patterns for identification and access control, can indeed be expensive to implement. This cost comes from several factors. First, the technology required to capture and analyze biometric data can be significantly more expensive than traditional security measures like passwords or PINs. High-quality biometric sensors, software for analysis, and secure storage systems for biometric templates contribute to the overall investment.

Additionally, implementing biometric systems may require substantial infrastructure changes, such as the integration of new hardware in existing access points or enhanced physical security measures to protect the biometric data itself. Training staff to utilize these systems and educate users about their benefits and limitations also adds to the costs.

While it is essential to recognize that biometric systems bring increased security and convenience, the initial financial outlay can be a substantial barrier to their adoption, making cost one of the primary disadvantages of such systems.
