Biometrics are in limited use today but there are obstacles to overcome before use of this technology becomes widespread. The cost of biometric products can range from less than one hundred dollars for a basic reading device to several thousand dollars for a fully integrated access system. The quality of the product must also be considered. The potential for inaccurate reading makes management doubtful of rolling the concept of biometrics out, for fear of denying access to legitimate users. Lack of standards that would integrate biometrics with mainstream PC technology adds to the slow acceptance of various technologies that fall under the biometric umbrella.
Most systems use proprietary techniques to store and exchange data, which compounds confusion.
Biometrics has also come to the attention of the religious community. Questions have been raised as to whether biometrics will contribute to the eventual loss of human identity. The most important issue hinges on our right to privacy. The public view of biometrics is intrusive. Organizations will have to overcome the consumers fear of privacy invasion.
