Disadvantages of Biometric Access Control Systems
Although biometric control systems provide great security, they do have some limitations, as we’ll explore below.
1. Physical changes can interfere with the accuracy
Although a person’s biometric data never changes, their physical attributes can change over time, which is why biometrics are not infallible.
According to a recent report by Antill, “The authentication system only identifies traits that were registered and fails to identify the user if their physical traits change in even the most insignificant way. In such circumstances, the system needs to be altered to grant access to the allowed user, which can be inconvenient.”
Examples of scenarios where traits may change include damaged or burnt fingertips, retina transplants or infection, the addition/elimination of glasses, or new tattoos on the individual’s hands.
2. Not all biometric systems suit every application
Different circumstances, like environmental factors, can determine how efficiently a biometric system works for your business. Sometimes, facial recognition may not suit your business if you operate in an industry where employees must wear masks all day. Fingerprint technology might not be a great fit if your business requires your employees to carry items frequently.
While many biometric systems are fairly accurate, you need to take extra care to ensure you settle for a system that is most suitable to your business.
3. Resetting biometric systems can be problematic
It is usually difficult to collate and replace biometric data within the system. A recent statement by Julien Raby, CEO and founder of Thermo Gears sums it best: “One of the biggest disadvantages of biometrics is that biometric data cannot be changed or reset.
If a password is stolen from a database, a new password can be created. But if a biometric characteristic is stolen from a database, a new biometric characteristic cannot be easily issued.”
4. Initial investment may be too expensive
The initial investment in a biometric access control system may be too expensive for small businesses to handle. While saving cost is a potential advantage, the hardware setup and integration require a significant investment that may be difficult for small businesses to bear.
Before setting up a biometric control system, small and mid-size businesses have a lot to consider before integrating one into their business. Regardless of the drawbacks, you have access to a wide base of knowledge about which technology can guarantee consistent ROI in the long term.
