Project Background: Jayaprakash Narayan Public Library (JPL Delhi)
Jayaprakash Narayan Library (JPL), operated under the auspices of the Zaheer Science Foundation at Gole Market, New Delhi, is an esteemed public research and community library housing thousands of scientific, academic, and historical volumes. The library administration sought a modern, unobtrusive anti-theft security solution to prevent unrecorded book departures while maintaining open architectural aesthetics and swift patron entry without physical turnstiles.
RFID Softwares engineered and executed the complete turnkey deployment of our HF RFID Security Gate (13.56 MHz ISO 15693). The system seamlessly communicates with the library's Koha Integrated Library System (ILS) via the SIP2 protocol, ensuring 100% autonomous detection without requiring continuous network polling.
Heavy-Duty Wooden Crate Transit & Unboxing
Because high-frequency library security gates feature precision transparent acrylic pedestal panels with internal multi-axis antenna coils, secure freight transportation is critical. The entire dual-pedestal gate assembly was shipped in a reinforced, shock-absorbing industrial wooden crate designed to withstand transit vibrations and eliminate micro-fracturing risks.
Upon arrival at the Gole Market library premises, our installation engineers conducted a thorough unboxing protocol: removing the wooden exterior, verifying structural integrity, checking acrylic clarity, and positioning the master and slave pedestals at the library doorway.
Reinforced Industrial Wooden Packaging
Custom-built shock-dampening wooden crate ensuring zero transit vibration damage to internal RF loop coils.
Pedestal Inspection & Pre-Positioning
Pedestals unboxed upright for optical transparency check, base mounting alignment, and entrance clearance layout.
Base Enclosure & Reader Module Electronics Architecture
The intelligence of the RFID security gate resides within the lower base compartment of the master pedestal. By releasing the bottom recessed stainless-steel mounting screws, the protective aluminum cover lifts off to expose the core electronic architecture.
The modular layout houses a 13.56 MHz high-power multi-channel reader board, a regulated industrial 24V DC switch-mode power supply, an Ethernet TCP/IP controller, multi-color LED driver boards, audio alarm buzzers, and GPIO terminal blocks for synchronization with the slave antenna pedestal.
Removing Lower Aluminum Chassis Screws
Accessing internal electronics requires removing the recessed bottom countersunk screws to lift the metal shield.
13.56 MHz Reader Module & Power Supply
High-power HF reader board, 24V DC SMPS, Ethernet controller, and master-slave bus terminal headers.
Hardware Cabling: Multi-Axis Antenna Loops & Master-Slave Bus
Flawless 3D omnidirectional book reading requires precision impedance-matched cabling and strict noise isolation. The wiring workflow encompasses three dedicated interconnects:
- Coaxial RF Antenna Feeds: 50Ω RG58 shielded coaxial cables route RF excitation signals from the master reader's high-power RF amplifier to the loop antennas in both acrylic pedestals.
- Master-to-Slave Synchronized Bus: Shielded multi-core control cable links the master unit to the slave unit to synchronize RF burst cycles and drive the slave strobe/siren simultaneously.
- Power & Underfloor Conduit: 220V AC input stepped down to regulated 24V DC, routed through an underfloor ADA-compliant metal raceway across the 1.1m entrance corridor.
Connecting Antenna & Power
Tightening 50Ω coaxial SMA connectors and 24V DC terminal blocks to the reader.
Completed Wiring & Isolation
All RF and power harnesses secured with strain reliefs to prevent signal cross-talk.

Base cover replaced and fastened; gate standing upright for network software calibration.
Anti-Theft Protocol Lab: AFI, EAS & DSFID Standards Explained
The gate's onboard DSP firmware supports four international anti-theft security standards to guarantee interoperability across different library management systems (Koha, LibSys, SLIM21, Soul 3.0):
Security Protocol Selection GUI
Toggle between AFI Byte (0xC2), 1-bit Hardware EAS, Dual Lock, or ISO 28560 DSFID modes.
| Protocol | Alarm Value | Checkout Value | Standard |
|---|---|---|---|
| AFI (Selected) | 0xC2 | 0x07 / 0x00 | ISO 15693 / Koha SIP2 |
| EAS | Bit = 1 | Bit = 0 | NXP ICODE SLIX EAS |
| EAS + AFI | Bit=1 AND 0xC2 | Bit=0 OR 0x07 | Dual Lock Security |
| DSFID | Format Bit | Parsed by ILS | ISO 28560-2/3 |
Firmware Setup, Ethernet Calibration & AFI Trigger Rule
Connecting a laptop to the gate's RJ45 Ethernet port, our team launched the configuration utility to tune RF output power, calibrate infrared sensor beam breaks, and define the AFI alarm filter rule.
By configuring the target AFI trigger code to 0xC2, the gate continuously scans passing 13.56 MHz tags in 3D orientations. If an un-issued book is detected, the internal relay triggers the high-intensity red LED strobes and audible sirens within 30 milliseconds.
Software & LAN Configuration Walkthrough
Watch the real-time PC software calibration over Ethernet LAN, setting sensitivity thresholds and verifying AFI 0xC2 socket triggers.
Configuring AFI Code 0xC2 in Middleware
Setting the active security filter in the gate controller. Tags with AFI matching 0xC2 immediately trigger audio/visual alarms upon entering the RF field.
Smartphone NFC Tag Verification (iOS & Android)
A key operational benefit of ISO 15693 HF RFID is that anyone can audit book security using a standard smartphone with NFC:
- Launch any standard NFC app (such as NFC Tools or NXP TagInfo) on an iPhone or Android smartphone.
- Hold the smartphone against the book tag sticker.
- Issued Book: Displays
AFI: 0x07or0x00→ Walking through the gate is completely silent. - Un-issued Book: Displays
AFI: 0xC2→ Walking through the gate triggers instant alarm strobes and sirens.
Silent Pass Authorization
Tag AFI security byte is cleared upon checkout at the Koha circulation desk or self-service kiosk, allowing silent patron passage.
Instant Gate Alarm Trigger
AFI byte is locked at 0xC2. Crossing through the gate triggers loud audio buzzer sirens and bright red pedestal LED flashing.
Live 3D Omnidirectional Testing & Patron Footfall Counting
Following calibration, our engineering team conducted exhaustive walk-through tests. Books were tested in vertical, horizontal, stacked, and backpack-concealed positions. The 3D loop antenna demonstrated 100% detection reliability across the entire 1.1-meter doorway width.
Integrated infrared sensors provide continuous bidirectional patron passage counting, showing live visitor footfall tallies on the pedestal's digital LED screen.
