Prisoner management in Kisii Prison had long been a neglected area and had only recently been included in the 2030 vision document under the e-governance. Currently, prisoner’s records are maintained in a very rudimentary way in the form of manual files and registers. This method of data management often resulted in human error, delay to retrieve information etc. Thus, An Prison Management System was designed and implemented to manage prisoner’s records for the Kilgoris prison. The project was implemented successfully and the result obtained provides a single management system which integrates all the information about a prisoner in a single profile and can easily be accessed which improved the overall efficiency of prison management. The system was implemented using PHP MySQL CSS HTML and JavaScript.
