摘要：Radio fr equency identification (RFID) technology has helped many or ganizations to reduce cost. Never theless, ther e are challenges and issues associated with RFID adoption. The most common internal challenge for many or ganizations is justifying the investment and modification of processes. The focus of this project is to show the business value of RFID technology and its applications. The important issue is the security level of the whole campus because it needs to be carefully differentiated. Dormitories and special research laboratories should benefit from higher levels of security than any other campuses. The ke y to the problem is represented by the new Radio Frequency Identification (RFID) which can support contactless cards with memory. The most important feature of the pr oposed system is the updating of access permission l evel at any time for the user based on the availability of that user . The data transfer fr om the reader to the database was done using wir eless communication (RF communication). To achieve this here RF transmitter and the RF receiver is used. The data which is read by the reader is sent to the micr ocontroller. Then fr om the contr oller we can transfer the data to the database by using the UART module (serial communication) which is inbuilt in the microc ontr oller through RF transmitter. RF receiver of the s am e frequency a t the re ce iv er e nd receives and then stor es the data in the database. RF transmitter and Receiver – frequenc y for transmitting and receiving the data depends on the user as per the requirement for the application and it is based on the range of distance. For the data encoding and decodi ng pr oce ss HCS-101 pr otocol is used
