How do you make an RFID based attendance system?
How to Operate RFID Based Attendance System Circuit?
- After making all the above connections, Switch on the circuit.
- On LCD it is displayed “PLEASE SWIPE THE CARD”.
- Place the RFID tag near the reader.
- Reader then reads the data in the tag and transmits to the controller.
What microcontroller is used for RFID?
This wireless RF Identification is used in many systems like RFID Based Attendance System, security systems, voting machines etc. This project will also serve as a proper interfacing of 16*2 LCD with 8051 microcontroller….8051 Microcontroller:
| Feature | 8051 | 8052 |
|---|---|---|
| Interrupt sources | 6 | 8 |
What is RFID based system?
Abstract: RFID is a technology similar to that of bar code scanning. An RFID system consists of tags, which use radio frequency signals to transmit its location information to a reader, which usually sends this information to a server that processes it according to the needs of the application.
What is RFID reader?
The RFID reader is a network-connected device that can be portable or permanently attached. It uses radio waves to transmit signals that activate the tag. Once activated, the tag sends a wave back to the antenna, where it is translated into data. The transponder is in the RFID tag itself.
What is RFID example?
For example, an RFID tag attached to an automobile during production can be used to track its progress through the assembly line, RFID-tagged pharmaceuticals can be tracked through warehouses, and implanting RFID microchips in livestock and pets enables positive identification of animals.
What is attendance system?
Time and attendance systems (TNA) are used to track and monitor when employees start and stop work. A time and attendance system enables an employer to monitor their employees working hours and late arrivals, early departures, time taken on breaks and absenteeism.
WHAT IS fingerprint attendance system?
Fingerprint attendance system aims to automate the attendance procedure of an educational institution using biometric technology. This will save time wasted on calling out names and it gives a fool-proof method of attendance marking. A hand-held device is used to mark the attendance without the intervention of teacher.
Why RFID is used?
RFID tags are a type of tracking system that uses radio frequency to search, identify, track, and communicate with items and people. Essentially, RFID tags are smart labels that can store a range of information from serial numbers, to a short description, and even pages of data.
How is an RFID reader used?
A radio frequency identification reader (RFID reader) is a device used to gather information from an RFID tag, which is used to track individual objects. Radio waves are used to transfer data from the tag to a reader.
What is the use of RFID module in PIC microcontroller?
RFID Interfacing with PIC Microcontroller. RFID stands for Radio Frequency Identification. RFID module can read or write small amount of data into a Passive RFID tag, which can be used in identification process in various systems like Attendance system, security system, voting system etc. RFID is very convenient and easy technology.
What is RFID based attendance system?
RFID Based Attendance System: RFID is very popular in electronics and microcontroller based projects . The RFID stands for radio frequency identification. It is the technology that used the smaller computer chip to track the person from some distance almost 300 feet. This chip can carry the 2000 bytes or greater data.
What is the use of a UART module in an RFID system?
RFID module can read or write small amount of data into a Passive RFID tag, which can be used in identification process in various systems like Attendance system, security system, voting system etc. RFID is very convenient and easy technology. To read the Passive RFID cards and tag, we need a microcontroller with UART hardware.
How to read passive RFID cards and tags?
To read the Passive RFID cards and tag, we need a microcontroller with UART hardware. If we select a microcontroller without UART, we need to implement software UART. Here we are using PIC Microcontroller PIC16F877A for interfacing RFID. We will simply read the unique identification no. of RFID tags and display it on 16×2 LCD.
