RFID is an acronym for radio frequency identification

RFID is a member of automatic identification and data(AIDC) technologies and is fast and reliable means ofidentifying just about any material object

Active RFID tags are powered my an internal batteryand are typically read/write i.e., tag can be rewrittenand/or modified. An active tag's memory size variesaccording to application requirements

DESCRIPTION

WORKING OF RFID Tags (or chips) consist of two parts:

1) Antennae 2)Processor/ storage

Receives signal from readerand gives a return signalwith ID number

Reader sends number todatabase or server

TYPES ACTIVE: Tag signal availability of 100ft. HIGH signal

strengthexample : Railway cars on a track

PASSIVE: Tag signal availability < 10 ft. VERY LOW signalstrength ( Widely used because very cheap to make)

APPLICATIONS Advanced Product Tracking

•Real- time data management•Dramatic benefits to manufacturing process

Quick Convenience•Grocery Store, Library, Hospital•Instant identification & time saver

Safety and Security•Locate/identify missing persons•Monitor prisoners

Easy Access•Access by authorized personnel only•Ease security concerns

RFID v/s Bar Codes Does not require human to manually pass item over

scanner.More accurate inventory count. Can be incorporated into product, person, animal. Can track each individual item.

WORKING

RFID card is detected by the reader module if it in therange of 10 cm.

After reading the card it checks the database. After checking database it decides that card is duplicate

or not. According to database it controller increases the count

for that specific lecture and store it in database

SYSTEM COMPONENTS

RFID UHF Fixed Reader:The UHF Reader Received the Data/Information Automatically as Card come inRange and Sends the Data/Information to PC or Server. Frequency: 860-960MHzProtocol-ISO 18000 6C EPC Class 1 Gen 2Operation: -30°C to +75°CSupport : RS232, RS485, TCP/IPSupport Auto-Running, Interactive and Trigger-Activating Work Mode

RFID UHF Desktop Reader:The UHF Desktop Reader is used for Tagging, in which Mapping of the RFIDTags with Employees/Visitors Ids is Being Done. Frequency: 860-960MHzProtocol-ISO 18000 6C EPC Class 1 Gen 2Operation: -30°C to +75°C Support : RS232, RS485, TCP/IP

SYSTEM COMPONENTS

RFID Security Gate: The UHF Security Gate is used for Track/Detect the RFIDTagged Employees/Visitors Movement Through the Entry &Exit. RFID Security Gantry Arrangement Single Lane Consistof Two Pedestals.

Specification:Protocol-ISO 18000 6C EPC Class 1 Gen 2Operation: -30°C to -+70°C Support : RS232, RS485, TCP/IPFrequency Support: 865-868 MHz Inbuilt Anti-Collision Algorithm.Audio Visual Alert Facility.Controllable Volume for Alarm

SYSTEM COMPONENTS

RFID Handheld Reader: The Handheld RFID Reader is a Movable RFID Component thatProvides Mobility and gives Ability to make Inventory and Trackingthe Location of Employees in the Entire Building, Floor andOrganization Easily with Comprehensive Range of Data from RFIDCards to Application Software. With this Flexible Multi-FunctionHandheld RFID Reader, which Reads Data in Remote Areas whereFixed RFID Readers can’t Reach.

Specification:Read Range: 0.2ft to 8 ft. Antenna: Integrated, Linearly PolarizedFrequency: 860-960MHzProtocol-ISO 18000 6C EPC Class 1 Gen 2

SYSTEM COMPONENTS

RFID Patron/I-Card:Laminated PVC (flexi/hard)Unique ID Eliminates Risk of Duplicate CardsPersonalized with Relevant Information about the EmployeesCompatible with other Auto-Id Systems–Access Control e-Payment, e-Attendance etc

Specification:Surface: Glossy FinishIC: NXP I CodeFrequency: 860-960MHzProtocol-ISO 18000 6C EPC Class 1 Gen 2

SYSTEM COMPONENTS

Web/Android Application Software:The RFID Attendance and Access Control Systems Application Software Formsthe Backbone of the Whole RFID System. It Performs End to End Functionalityi.e. Add, Edit, Search and Reports from Programming the RFID Cards, which isto Query the System for Locating the Position of Particular Employee/Student/Staff/Visitor along with Detailed Information.

CONCLUSIONS

This project is a full system for employee and studentmonitoring in office and high education institutes.

The device is supported with friendly using softwarefor data analysis and previewing .

Lecturers need no more wasting time, and effort tohave their Attendance Register .

Attendance Register now, easily uploaded to Database.

APPLICATIONS USE

Employee Attendance School Attendance
