This document describes an RFID system project that uses an Arduino Uno, ATmega 328p microcontroller, EM-18 RFID reader module, passive RFID tags, real-time clock, and 16x2 LCD. It explains the hardware and software components, including how the RFID reader detects tags and the microcontroller registers entries and exits to the LCD display. Key aspects of RFID technology like tags, readers, and middleware are also overviewed at a high level.

2. Introduction
1.What is a RFID system?
Hardware requirements
1. ATMEGA 328p Microcontroller
2. EM-18 Module (RFID Reader)
3. Passive tags
4. RTC (Real Time Clock)
5. PCB
6. LCD(16*2)

3. List of software and tools used
1. ARDUINO IDE
2. EXPRESS PCB
3. ARDUINO UNO

4.  RFID stands for Radio Frequency Identification.
 RFID is a technology which wirelessly identifies the
chip or tag of interest and captures the data.
 It is a member of AIDC(Automatic Identification and
Data) technologies.
 RFID system comprises of
1. RFID tags
2. RFID reader
3. RFID middleware.

5.  RFID tags contain a wire circuit and antenna for
data transmission.
1. Active 2. Passive

6.  RFID readers are devices
which emits radio signals
through antennae.
 They also provide the
necessary amount of power
to the tags, if passive tags a

7.  It collects all the data that tags give, does the
filtering task.
 RFID middleware actually is used to control
and manage the RFID readers’ infrastructures.
 It is considered as the brain of any
 RFID system as it provides the most important
functionalities.
 Some of its key functionalities are efficient
management of data created by the RFID
system.

8. 1. ATMEGA 328P Microcontroller
 28-pin AVR Microcontroller
 Flash Program Memory: 32 kbytes
 EEPROM Data Memory: 1 kbytes
 SRAM Data Memory: 2 kbytes
 I/O Pins: 23
 A/D Converter: 10-bit Six Channel
 RTC: Yes with Separate Oscillator

10.  Operation voltage
5V DC
 Current of operation
is less than50mA
 Frequency of
operation: 125 KHz
 Distance of operation
10cm

11.  This tiny RTC module
is based on the clock
chip DS1307 which
supports the I2C
protocol.
 It uses a Lithium cell
battery (CR1225).

12.  We used a 16*2 LCD
means 16 columns
and two rows.
 It has 14 pins.

16. Tag is detected and entry registered

17. Same tag detected again and exit
registered
