Abstract
To provide a system for monitoring and locating objects using Radio Frequency (RF) transmitters and receivers, and querying about the objects using mobile phones. An object represents a real world entity. This system is based on RF transmitters that are tagged to the objects of everyday use and have the capability of transmitting signals and a receiver that detects the transmission of the tagged object and stores its corresponding location in the database which is created specifically for information maintenance of the tagged objects. Mobile phones are used to query the location of the tagged object by sending a message to the Subscriber Identity Module (SIM) connected to a Global System for Mobile Communications (GSM) modem. This GSM modem fetches the location and other relevant information from the database and encapsulates this information into a message which is sent back to the mobile phone that has requested the information.
