RFID BASED OFFICE ATTENDENCE LOGGER
[attachment=26133]
Radio Frequency Identification (RFID) is a general term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object wirelessly, using radio waves. RFID is evolving as a major technology enabler for tracking goods and assets around the world.
RFID is the reading of physical tags on single products, cases, pallets, or re-usable containers that emit radio signals to be picked up by reader devices. The complete RFID picture combines the technology of the tags and readers with access to global standardized databases, ensuring real time access to up-to-date information about relevant products at any point in the supply chain.
Tags contain a unique identification number called an Electronic Product Code (EPC), and potentially additional information of interest to manufacturers, healthcare organizations, military organizations, logistics providers, and retailers, or others that need to track the physical location of goods or equipment. All information stored on RFID tags, can be scanned wirelessly by a reader at high speed and from a distance of several meters.
In this project we are going to implement an office attendance logger by using RFID cards and reader. Every employee has a specific RFID card with unique employ ID. When ever he enters into the office the reader reads that id and stores the in- time of the employee and if he leaves the office the system stores out-time of the employee.
Since the no. of employs in an office is having their own RFID tags, all the tag holders’ office timings are recorded in a memory device. For this user has to interface the external memory based on requirement. This data can be uploaded into the PC by using serial communication. Now the memory device can be free for recording the new attendance log.
Applications are Item visibility and status, Location tracking, Access control, easy billing etc.
