Here in this project we are using Arduino and relay to trigger the Electric Door Lock and RFID to authenticate, so your RFID tag will act as a key. If you place wrong RFID card near RFID reader a buzzer will beep to alert about wrong card.

An Arduino Uno is used in this do-it-yourself RFID attendance system to track students and employees automatically. comprehensive project tutorial that includes LCD interface, circuit connections, programming code, and helpful implementation advice for beginners.

RFID based Secured access system implemented on 8051 microcontroller . This is a very useful application of RFID and is very commonly used in institutes, offices, homes and so on. An RFID system consists of a reader device and a transponder. A transponder or tag has a unique serial number which is identified by the reader.

In this RFID based Attendance System project, we will explain you how can we count attendance automatically by using RFID cards. RFID Tecnology (Radio Frequency Identification and Detection) is commonly used in schools, colleges, office and stations for various purposes to automatically keep a track of people. Here we will count the attendance of an authorised person by using RFID.

In this project we are going to design a RFID based toll plaza system for security purposes. So this system open gates and allow people only with the authorized RFID tags. The authorized tags holder ID’s are programmed in to the ATMEGA Microcontroller and only those holders are allowed to leave or enter the premises.

Last time, I posted an ultra-simple “from scratch” RFID reader, which uses no application-specific components: just a Propeller microcontroller and a few passive components. This time, I tried the opposite: building an RFID tag using no application-specific parts.
