  RFID BASED PROJECTS

The attendance system is basically an embedded one. Embedded stands for ‘hardware controlled by software’. Here, the software using a Microcontroller controls all the hardware components. 

The microcontroller plays an important role in the system.
The main objective of the system is to uniquely identify and to make attendance for a person. This requires a unique product, which has the capability of distinguishing different person. This is possible by the new emerging technology RFID (Radio Frequency Identification).  

The main parts of an RFID system are RFID tag (with unique ID number) and RFID reader (for reading the RFID tag). In this system, RFID tag and RFID reader used are operating at 125KHz. The EEPROM used for storing the details has the capability of storing 256 person details at a time. The PC can be used for restoring all the details of attendance made.
This report provides a clear picture of hardware and software used in the system. It also provides an overall view with detailed discussion of the operation of the system.

2.  RFID Based Attendance System with password protection

The attendance system is basically same as above project with additional password protection system.

Ie Access = authorize card + Right password.

3. RFID Based Security System

This project aimed to develop a wireless system to detect and allow only the authorized persons. The system was based on Radio Frequency Identification (RFID) technology and consists of a passive RFID tag.

The passive micro transponder tag collects power from the 125 KHz magnetic field generated by the base station, gathers information about the Tag ID and sends this information to the base station. The base station receives, decodes and checks the information available in its Database and Manchester code was used to send those information.

The system performed as desired with a 10cm diameter antenna attached to the transponder. The Base Station is built by using the Popular 8051 family Microcontroller. It gets the tag ID and if the tag ID is stored in its memory then the microcontroller will allow the person inside.

RFID Reader Module, are also called as interrogators. They convert radio waves returned from the RFID tag into a form that can be passed on to Controllers, which can make use of it. RFID tags and readers have to be tuned to the same frequency in order to communicate. RFID systems use many different frequencies, but the most common and widely used Reader frequency is 125 KHz.                                                                                                                                               

4.  RFID Based Security System with password protection

The security system is basically same as above project with additional password protection system.
