Is a Biometric device an input output or storage device?
Most biometric devices would be input devices although they may also utilize storage devices and output devices in their functioning. A biometric device usually takes in biometric information about a person and compares it to information stored in a database - much like username/password methods of authentication compare the username and password to the stored information for a user. Fingerprint scanners, read the fingerprint, convert it to a data stream and then compare it to the stored data previously recorded for the individual, retinal scanners read information about the retinal patterns of a user, convert it to data and compare it to stored data, etc. Note that biometric devices must rely on a storage device, but usually the storage device is not part of the biometric device. Instances of OUTPUT associated with a biometric device might be a signal to open a door or trigger an alarm, but again, the output usually comes from another device that the biometric device is connected to.

Can you use a power adapter that has less amp input?
The rule with power adapters is generally that the voltage must be the same as the device's input voltage requirements. However, the amperage just has to be equal to or greater than the device's input current requirements. The device will draw as much current as it needs. But, mismatching voltages can destroy electronic equipment.
