ThingMagic Gemini (HF)

Enabling HF/LF RFID Secure Access in a Compact, Embedded Module

Manufacturer: JADAK
ThingMagic Gemini (HF)
Introduction

The ThingMagic® Gemini is for OEM designers requiring maximum customizability in an RFID module that reads and writes to MIFARE and NFC protocols, including capabilities for NFC peer-to-peer and NFC tag emulation (ISO 18092).

The Gemini supports the mutually authenticated Triple Data Encryption Standard (3DES) encryption, ideal for applications in product authentication and consumable protection (i.e. anti-counterfeiting).

It’s outfitted with 4 General Purpose Input Output (GPIO) pins; other available interfaces include micro USB for direct connection to a USB host, Common Blade Interface, the software adjustable host interfaces UART (TTL), SPI and I2C, and the capability to attach an external antenna for greater read range.

With a form factor approximately the size of a matchbook, the Gemini is a powerful, cost-effective embedded RFID solution for OEMs requiring a simple and intuitive API and accelerated time-to-market.
