The fingerprint readers increase the security level of the house by eliminating the risk of a key ending up in the wrong hands. Only the person authorized access can successfully pass a biometric reader and it also requires that the person be physically present for access to be granted. This naturally leads us to the question of reliability. For most models, the false acceptance rate is about 1/100,000, making them extremely reliable. In the event that an authorized person is denied access, most fingerprint door locks have an alternate way to gain access. The ideal set up for fraternity house usage would allow for at least two access levels. The higher level should be held by a member of the House Corporation. That person would be in charge of emergency access as well as setting up the system each semester for new members. The lower level would consist of undergraduates and others who shouldn’t have the ability to change the system.

Despite its modern technology, these systems are surprisingly affordable. Battery operated models that hold 100 fingerprints can be found for under $300.00. These models are as easy to install as a traditional deadbolt. These models use 4 AA batteries which usually last around one year. Most models also have a backup 9V battery to protect all of the fingerprint information while the primary batteries are being replaced.

Fingerprint readers that are hardwired into a system are substantially more expensive, but offer a much larger range of access options and hold more fingerprints. You also never have to worry about changing batteries. Most hardwire systems can also be set up to be monitored by your regular alarm company.
