Versatile card reader for mobile and desktop users

The IOGEAR GFR3C12 is a compact external card reader designed for photographers and professionals who move files between smartphones, tablets and computers. It accepts both SD and microSD cards through dual slots, removing the need for separate adapters. USB On-The-Go support lets Android 2.3+ devices read cards directly without installing extra apps.

Dual-slot capacity with broad OS support

The reader handles standard SD and microSD cards in a single device, so you can offload photos from a camera and expand phone storage with one tool. Compatibility spans Windows 7 through 10, Mac OS X 10.7+, Chrome OS and Linux, covering most laptops and desktops in service today. Older operating systems or proprietary card formats are not supported.

Passive cooling and bus-powered operation

An aluminium body dissipates heat during sustained transfers without a fan, keeping the unit silent on a desk or in a bag. Power comes entirely from the host USB-C or USB-A port, so no external supply is needed. The included silicone cover protects the connectors from dust and damage while travelling.

Yes, the reader supports Windows 7 and Android 2.3 or later through its USB-A and USB-C connectors.

How can I confirm the card reader is functioning correctly after plugging it in?

Insert an SD or microSD card; the drive should appear in your file manager without installing any driver or app.

Does the package include a cable or do I need to buy one separately?

The box contains the GFR3C12 reader and a protective silicon cover; no separate cable is required because both USB-C and USB-A connectors are built in.
