Abstract--- RFID technology has long been recognized as an efficient method for identifying a single entity. We use the RFID reader to identify an existing employee when the employee swipes his/her ID to login. The acquired data is then checked to retrieve the personalized details of that specific employee stored in the centralized database. RFID technology also provides potential for greater security and privacy for the user of the kiosk system as compared to traditional magnetic strip methods. The system allows the retrieval of attendance details, medical bill status, leave transaction details, pay slip details, file status and capital item details for employees in a detailed form. The developed web based information kiosk is easy to use and provides quicker accession time for retrieving personalized information. This system is especially helpful for employees who do not have a dedicated computer for their personal use and others who are not acquainted in using computers on a day to day basis.

specific RFID application or middleware pilots the reader and processes the data it sends. RFID has great characteristics: 1. It is possible to scan tags in motion and 2. Since radio waves can pass through most solid objects, the tags don’t need to be in direct line of sight of the RFID reader. RFID tags are either ‘passive’, having no battery or ‘active’, which are self-powered by a battery. Tags can also be readonly (data once stored can be read but not changed), read/write (stored data can be altered or re-written), or a combination of both, in which some data (such as the serial number identification or SID) is permanently stored while other memory is left accessible for later encoding or updates.

Employees are the most valuable and dynamic assets of an organization. Radio-frequency IDentification (RFID) technology is the use of an RFID reader attached to a kiosk in order to identify every existing employee using radiofrequency waves. Many different industry sectors have started using RFID technology as an important tool to optimize their effectiveness and efficiency, though initially RFID found a negative response in the sector, with charging trends, it has become an indispensible part. The paper presents a developed Information Kiosk for employees is an extensive and comprehensive system that displays the information pertaining to all the employees in an organization. Our system identifies every employee using their unit code and employee no after reading the RFID tag from their ID using the RFID reader. A welcome page is then displayed which has all the subsequent modules containing the specific details of that particular user. In this system, both the RFID tag and RFID reader are operating at 13.56 MHZ. II. RFID TECHNOLOGY Radio Frequency IDentification (RFID) is a method for remotely storing and retrieving data using devices called RFID tags or transponders. An RFID tag is a small object, such as an adhesive sticker, that can be attached to or incorporated into a product. RFID tags are composed of an antenna connected to an electronic chip. Finally, a computer hosting a

Around the globe many people/organization are involved in research and development related to RFID technology. One of the works is done on Mobile RFID Reader with Database Wireless Synchronization [2]. People have implemented the mobile RFID reader using a PDA, an OEM flash card reader module, RFID passive tags and a database. The reader opens a serial port and then reads a tag to use it as an index key in the database to access and show the record associated to the tag. Any change is wirelessly synchronized to a database server. IV. PROPOSED ARCHITECTURE The proposed system architecture is mainly classified into two category i.e. Software architecture and Hardware architecture. 1. Hardware Architecture We have used an ATmega162 microcontroller for this system. This microcontroller has 16KB Flash program memory & 1KB SRAM. All the sections are controlled by the ATmega162 microcontroller and the required code to control the sections is written in MikroC PRO software. The basic block diagram is shown below in Fig 1.

a. RFID Reader module The RFID reader module is responsible for reading the data present in the card. To read data from the card, the microcontroller sends command to the reader module along with authorization key through UART interface. Since the card data is protected with authorization key to avoid unauthorized access. If the card is authorized then it sends the data to the microcontroller with acknowledgment, checksum etc. We have used RDM880SE as our RFID reader module. The details specification is shown in Table 1 Protocol Supported
