Schools have their own particular data: students, books, devices, classrooms, and daily attendance.
RFID can help schools with attendance, access control, library systems, inventory tracking, payment processing, and student bus transportation records. All of these uses require different sets of RFID products ,such as RFID card , RFID Tag .
What Is RFID in Schools?
RFID in schools is the use of RFID technology to manage students, teachers, books, assets, and other activities within a school.
It can be used for attendance, access control, library management, asset management, and payments.
How Does an RFID System Work in a School?
Main Components of a School RFID System
A typical RFID system for a school consists of the following components:
- RFID cards, tags, wristbands, or key fobs
- Readers and antennas
- Software and databases
- Integration with school systems
How RFID Identification Works
Whenever a tag is read, the reader is able to transmit the tag’s ID to the software.
After that, it will make the program perform an action, for instance, record attendance or open the door.
Passive tags do not have a battery and are only read at close range by a compatible reader.
What Is RFID Used for in Schools?
RFID Student Attendance
Schools can use either tap-based HF cards or longer-range UHF cards for contactless attendance. HF cards require students to tap a reader, while UHF cards can be detected from a distance. Readers, sensors, and related software can help prevent duplicate scans and identify errors.
However, cards kept inside a bag may still be read, though less accurately than cards tapped directly on the reader. A card reader also cannot confirm that the cardholder is present for every scan. Once the record is verified, the SIS database can be updated and parents can be notified.
For example, a field study at a secondary school in Peru found that its 13.56 MHz RFID attendance system reduced administrative work by 50 minutes each day.
RFID Access Control and Student ID Cards
RFID-based access control can secure gates, dormitories, laboratories, and staff-only areas. Access rights can be assigned based on the person, area, calendar, or schedule. Lost cards can be blocked by staff. Secure areas should use protected authentication. A card’s unique ID alone can be duplicated.
RFID in School Libraries
RFID facilitates borrowings, returns, inventory, sorting, and security checks. Most libraries use 13.56 MHz HF tags compliant with ISO/IEC 15693 standards. ISO 28560 defines RFID information for library systems. Tags, readers, software, and data formats should be compatible. RFID helps identify books close to the reader. It cannot indicate the exact GPS location of a book.
RFID School Asset Tracking
RFID technology can be used to track loaning, returning, transferring, and storing of laptops and tablets, tools, and sports equipment.
Fixed readers can detect the movement of tagged items through particular doors but are unable to identify their precise location within the campus.
The reading accuracy can also be improved by using anti-metal tags, foam spacers, or special tags.
For example, the Metalcraft case study reveals that Yakima Valley College uses passive UHF RFID to track more than 7500 items and reduce classroom inventory time from about a quarter to five minutes or less.
RFID School Bus Management
RFID can record when a student boards or gets off a school bus. The system records the student, bus, stop, and boarding or disembarkation time. RFID identifies the student, while GPS identifies the location of the bus.
Cashless Payments and Cafeteria Management
RFID-based payment cards can be used for payments in cafeterias, vending machines, printing services, and school stores. The student taps their card, and the charge is applied to the linked account. Cashless payments require secure chips, protected keys, and transaction logs.
RFID Campus Card Systems
A campus card can support attendance, access control, library borrowing, and payments, but each service needs separate permissions.
Other RFID Applications in Education
Schools may also use RFID for:
- Visitor cards
- Events
- Uniforms
- Laundry
- Parking
- Lockers
- Staff identification
Which RFID Technology Is Best for Schools?
Choose the RFID type according to the needed read range, workflow, environment, and level of security.
| RFID Type | Typical School Use | Benefit | Limitation |
| LF | Basic access control and attendance | Short, controlled read range | Many basic LF cards have limited security |
| HF | Student ID cards and related services | Can be used for smart cards | Short reading range |
| HF ISO 15693 | School libraries and documents | Suitable for item management | System compatibility must be checked |
| UHF | Asset management and inventory | Many tags can be read | Affected by metal, people, and other factors |
| Active RFID | Real-time location systems | Can be read over larger areas | Higher cost and power requirements |
LF RFID for Basic Access Control
LF RFID is used in some older access control and attendance systems. The short read range allows for limited access, but many basic LF cards offer very limited security.
HF RFID for Student Cards and Campus Services
HF RFID is used for student ID cards, attendance, access control, payments, and other campus services.
Many cards use the ISO/IEC 14443 standard, but two different 13.56 MHz cards may not be compatible with each other. Check the protocols, chips, keys, readers, and data formats.
HF RFID for School Libraries
ISO/IEC 15693 tags are often used in library systems. This includes circulation, inventory, security checks, and self-checkout stations.
ISO 28560 may also be used to encode the library data on the tag.
UHF RFID for Asset Tracking
UHF RFID is a good choice for asset verification and contactless attendance systems.
Passive UHF RFID systems typically use the ISO/IEC 18000-63 standard or EPC Gen2 protocol. Metal, liquids, people, and distance can affect the reading range. It’s a good idea to test tags on or near the items.
Active RFID and Real-Time Location
Active RFID tags are powered by an internal battery and can sometimes be read at a greater distance. They can be used for real-time location tracking of assets or people.
Other options include BLE and UWB for indoor positioning. GPS is better for buses or other outdoor tracking.
Benefits of RFID in Schools
Faster Attendance Management
RFID technology can help automate the roll call process, allowing to measure the time spent on attendance management, number of missed scans, and staff workload.
More Efficient Library Operations
RFID can improve the speed and accuracy of library operations, such as book lending, returns, and inventory management, while also helping measure the time spent on each task and the rate of misplaced books.
Better Asset Visibility
RFID can capture information about equipment checkouts, transfers, returns, and inventory results. It can also help measure audit time, missing assets, and record accuracy.
Improved Access Management
RFID cards can store access permissions that can be updated in real time and applied instantly. This helps measure response times and unauthorized access attempts.
More Convenient Campus Services
A single card can be used for various services within the educational institution. This helps measure the time spent on each operation, the number of errors, and user satisfaction.
More Accurate Management Data
RFID technology can reduce the manual data entry, and automatically record the required information. This reduces the errors and measures recordkeeping time and data accuracy.
Challenges and Limitations of RFID in Schools
RFID performance depends on the tags, readers, antennas, software, network, and overall system. Tag placement, nearby metal or water, crowded areas, and the system’s read range can all affect performance. A long read range may also cause the system to detect cards or tags outside the intended area.
During the trial period, test the system under the following conditions:
- Crowded entrances
- Cards inside bags
- Grouped assets
- Repeated reads
- Cross-reads
- Network outages
- Power failures
Evaluate system performance based on read rates, false alarms, time saved, and staff feedback. Use the results to improve tag placement, reader power, antenna position, and software settings.
Student Privacy and RFID Security
What Information Is Stored on an RFID Student Card?
The card may contain identifiers, protected application data, access information, payment data, cryptographic data, or library records. To protect privacy, student records should be stored in the school’s database, while the card contains only the necessary information.
Can RFID Track Students in Real Time?
Depending on the technology, passive RFID tags can record when students enter, leave, or pass through specific zones equipped with readers. However, they’re not suitable for continuous real-time tracking.
Active RFID, BLE, UWB, or GPS may be needed for continuous location tracking, depending on the project.
Main RFID Security Risks
Schools may face:
- Cloning of student cards
- Theft or sharing of cards
- Weak key security
- Excessive staff access
- Poor database security
- Insecure software connections
How Schools Can Protect RFID Data
A school can reduce RFID security risks by:
- Limiting the data stored on cards
- Using strong encryption and secure key management
- Restricting staff access
- Deactivating lost or stolen cards
- Setting clear data retention policies
- Auditing system activity and data access
- Securing software connections
- Educating students, staff, and parents
FERPA, GDPR, and Local Privacy Rules
FERPA is a U.S. law that protects student privacy and applies to many schools that receive federal funding. COPPA and state education privacy laws may also apply in the United States.
GDPR may apply to educational institutions depending on the country and the personal data being processed.
Schools should also consider local laws on consent, access, storage, and data retention. This article does not provide legal advice.
RFID vs Other Technologies in Schools
RFID vs. Barcodes
Barcodes are cheaper but require people to scan them manually. RFID can automatically read multiple items at once, even when the tags aren’t visible.
RFID vs. QR Codes
QR codes work well for creating links. RFID is better for access control and tracking.
RFID vs. NFC
NFC is a type of RFID technology that works with many smartphones. However, not all RFID tags can be read by an NFC reader.
RFID vs. Biometrics
RFID uses a card or tag to verify identity. Biometric methods use facial recognition or fingerprints. Although biometrics can provide stronger security, they may also create greater privacy concerns.
RFID vs. GPS
RFID can identify students or other items when they are near a reader. GPS can track a school bus or mobile device when it’s outside.
