None of the card reader emulation systems can transfer template management data through the existing card-based system. Some biometric devices can be linked outside the card-based system, allowing users to enroll at a single terminal and have their templates distributed to the other readers. Some manufacturers of access control systems have integrated biometric units into their products. In this type of integration, the access control software handles template management and communications to the biometric devices. These may be subjective issues, but they are sufficiently important to require a clear and informative orientation session.
People like to use mechanical devices that are simple and intuitive.
Most biometric devices make such frustrations rare. It takes just a few minute to demonstrate proper use of the new technology. The biometric device must work correctly. Suffice it to say that biometric devices have proven extremely secure, reliable, and free of user frustrations in laboratory testing as well as in real-life applications. Throughput Throughput is the total time it takes a person to use the device.
