ELATEC TWN4 USB Front Reader-PI set

Embedding secure RFID, NFC, and Bluetooth Low Energy identification into Raspberry Pi projects often means wrestling with incompatible modules, fragile wiring, and limited protocol support. The ELATEC TWN4 USB Front Reader-PI Kit removes that friction, delivering a factory-matched front reader module and Raspberry Pi interface cable that snap together for instant, reliable credential reading.

Who is it for

Developers, integrators, and hobbyists building access control, time & attendance, asset tracking, or cashless payment systems on Raspberry Pi. It suits anyone who needs a compact, industrial-grade reader that handles legacy 125 kHz prox cards and modern 13.56 MHz smart tags without extra shields or soldering.

Main features

• Multi-frequency RFID/NFC: reads 125 kHz, 134.2 kHz, and 13.56 MHz credentials, including MIFARE, NTAG, HID Prox, Indala, EM4100, and more.
• Bluetooth Low Energy (BLE) for wireless credential exchange and configuration.
• USB 2.0 full-speed interface with HID, Virtual COM Port, and CCID modes – no driver headaches on Raspberry Pi OS, Windows, Linux, macOS, or Android.
• Integrated antenna, multi-colour LED, and buzzer for clear user feedback.
• Field-upgradeable firmware and comprehensive SDK for custom application development.
• Kit includes TWN4 MultiTech 2 BLE USB Front Reader module, USB cable, and Raspberry Pi interface cable/adapter.

Specifications

• Supported standards: ISO/IEC 14443 A/B, ISO/IEC 15693, ISO/IEC 18092 (NFC), FeliCa, MIFARE Classic/Ultralight/DESFire/Plus, NTAG, ICODE, HID Prox, Indala, EM4100, T5577, Cotag, G-Prox, AWID.
• Operating voltage: 4.3 V – 5.5 V DC via USB.
• Current consumption: typical 100 mA idle, max 200 mA during read.
• Operating temperature: -25 °C to +80 °C.
• Module dimensions (approx.): 50 x 40 x 15 mm (L x W x H).
• Housing material: ABS / PC.
• Security: secure element support, AES128 encryption for BLE.

Tips

Mount the front reader behind a non-metallic panel for a clean, professional look. Use the ELATEC SDK to map card UIDs to user accounts and trigger GPIO actions on the Raspberry Pi. For outdoor or industrial deployments, ensure the ambient temperature stays within -25 °C to +80 °C and protect the USB connection from moisture.
