Description

The Gemini SkyeModule marks the next generation of SkyeTek HF reader modules. The Gemini is a low-cost, and ultra-low power, MIFARE and NFC reader/writer module. A cutting edge ARM Cortex microcontroller and the latest HF transceiver technology, coupled with the reader's intelligent operating system make this module a most versatile HF RFID module. Manufactured and tested in the United States, quality is a top priority for all SkyeTek modules.

Supported security features like mutually authenticated triple DES encryption offer a low-cost and robust method of authentication for consumables, making the Gemini ideal for medical, ticketing, security or safety applications. At about the size of a matchbook, this module can be fit into almost any new or existing OEM design. The Gemini module is also well suited for battery powered and other power sensitive applications because of the low power features including software stand-by mode and deep sleep mode.

The Gemini module is one of the first to support not only the extremely popular NFC tags, but also NFC peer-to-peer and tag emulation modes as defined by ISO18092. This unique ability allows for active data passing between NFC enabled smart phones, tablets and other devices.

The Gemini is physically the same size and form factor as SkyeTek's very first and most popular module the M1. The Gemini module connector is updated to match the Common Blade Interface and can connect to the same interface board as any of the Common Blade devices (M2, M4, M7, M9 and M10). In addition, a micro USB port is available for direct connection to a USB host as well as an antenna output for an external antenna.

Note the standard Gemini module is provided without any connectors (USB or Blade Interface). UMD can provide connectors individually or mounted to the module.
