In day today's life security is a very important thing in the world. For better achievement of security advanced technology have been undertaken in correctional facilities. Various security devices like CCTV, Tracking bracelets, ID barcode scanning and other devices have contributed to the improved and secure management. The aim of this paper is to invent a security system against prisoner by using RF Transmitter and receiver technology. It is based on RF Transmitter and Receiver technology on ultra high frequency range which can be applied to use in access control by using RF Transmitter and Receiver tag. The RF Transmitter and Receiver tag contains a unique set of number as a code, so it can be identified. The RF Transmitter will act as the bracelet and the RF Receiver will be at the server side. For keeping the track of prisoner Global Positioning System (GPS) is used. This technology can be used for monitoring the prisoners in the jail, patients in the hospitals or mental asylums who basically try to escape or run away from jails and mental asylums. It tracks the particular person wearing the bracelet within its range and as soon as it's outside the range the GPS connected to the bracelet gets activated and we can track that particular person with the help of GPS on the bracelet. It's also very useful in the schools for students and the staff, colleges, employees in the offices and etc where we need to keep track of someone's presence. There is no need of keeping continuous watch due to this technology, for example if the prisoner runs away from the jail a message will be sent to the jailer and buzzer will ring. Due to this technique it will be easy for monitoring purpose.
