There are a lot of biometric technology to help people to authenticate greatly improve the safety factor, the inherent characteristics of humanity itself has a unique stability, are now very popular recognition technology. In the biological properties recognition technology, fingerprint recognition because of its uniqueness and stability has now become a hot recognition technology. Fingerprint recognition technology to become a human greatest discoveries. This article focuses on access control system in the cell design, cell-based fingerprint identification access control system is safe, convenient, and easy management features. Fingerprint Access Control System Intelligent Community security level coefficient is high, more convenient than the traditional means to reduce the loss of goods due to inaccessible trouble, compared to face recognition, iris recognition technology to identify the biological characteristics of the same, w
