Technology has the potential to transform the entire educational landscape of any country. From classroom management to safety and security on school, college, and library premises, IoT and AIDC technologies such as RFID and barcode can streamline day-to-day operations.
Various Internet of Things-based solutions can help educational institutions manage student and staff attendance and transform how they provide education.
Use of radio frequency identification (RFID), QR code, Barcode, BLE, etc. can be used to manage assets, track and trace assets and individuals, and effectively manage various educational programs. Similarly in the education sector, RFID technology can be used to prepare attendance sheets and streamline library operations such as borrowing and returning books, membership, book inventory management, etc.
What is RFID Technology? Understanding the Basics
Radio frequency identification (RFID) technology enables wireless communication between tiny electronic devices that can be attached to physical objects. Typically, RFID devices consist of a microchip that stores data and an antenna that transmits and receives radio signals (called RFID tags in combination). RFID tags can be read by special readers that send out radio waves and capture the signals reflected by the RFID tags or RFID-based devices.
These RFID tags can store data and can be attached to various objects, such as books, cards, or badges. RFID readers can send out radio signals and receive the data from the tags within a certain range known as the RFID read range (for the device).
RFID can be passive, meaning there is no battery involved with the RFID tag and it relies on the reader's signal for power, or active, meaning the RFID tags have a battery and can send out signals on their own.
RFID technology can be used for various applications, such as identification, tracking, authentication, and automation in distinct business domains.
RFID in Education
RFID is a technology that can also be used to enhance classroom management and safety and security at premises. It can improve classroom management by automating the attendance process, tracking the location and status of books and other resources, and providing information to students and teachers.
Consider this example, RFID tags can be embedded in student ID cards or badges, and RFID readers can be installed at the entrance of the classroom or the school. By doing this, when a student enters or exits the classroom or the school, the RFID reader can record the time and date of their attendance and send it to a database. This can save time and reduce errors in manual attendance taking, as well as provide accurate data for analysis and reporting.
RFID tags can also be attached to books and other materials in the library or the classroom, and RFID readers can be placed on shelves or desks for efficient inventory management, security, and circulation of the resources. RFID readers can also provide information about the availability, location, and details of the resources to students and teachers through a centralized user interface. RFID-based drop boxes are also quite popular allowing students to drop the books and journals they borrowed in a timely manner, without standing in a queue.
RFID can also be used to enhance safety and security at premises by preventing unauthorized access, theft, or misuse of resources, as well as providing emergency response and notification. For example, RFID tags or RFID cards can be used as access control devices that allow only authorized persons to enter certain areas or use certain equipment. RFID readers can verify the identity and authorization of the card holders and grant or deny access accordingly.
Many public and private schools in India are using RFID-based ID cards for their students and staff and RFID attendance tracking system to track the entry and exit timings of students and staff. Many private schools also notify the parents of the students upon their arrival and departure from the school premises. RFID readers deployed at entry and exit gates accurately track each movement.
RFID tags can also be used as anti-theft devices that trigger an alarm or a notification when a tagged item is moved out of a designated area without permission. RFID-based emergency devices in the form of wristbands can send out a distress signal or location information when a tag holder is in danger or needs help. RFID readers can receive the signal or the information and alert the authorities or the responders.
RFID is Very Popular in the Education Sector
RFID, as a short-range wireless technology can be used to manage classrooms and the safety of students at the premises quite effectively. In fact, many universities and public libraries around the world such as the Indian Institute of Technology, Delhi (IITD), IIT Mumbai, Handley Area Library, Virginia, USA (using RFID for automating check-in and check-out, inventory management, and security), Quebec Public Library in Canada (using RFID smart shelves to monitor location and status of books in real-time), Singapore National Public Library (uses RFID-based inventory management robot to scan and sort books on shelves), and Hong Kong Public Libraries ( uses Bluetooth Low energy, BLE, technology to help users with self-service, location-based service, and information, etc. ) are some of the famous educational places that use technology to enhance operations and user experience.
To summarize, RFID technology can help automate attendance taking, track resources, provide information, prevent unauthorized access, deter theft, and enable emergency response at schools and colleges. Various RFID-based solutions such as RFID attendance tracking systems, RFID visitor management systems, RFID asset tracking systems, RFID library management systems, etc. are actively used at various schools and colleges in India and around the world.
