SCM SCR3311 USB 1.1 Smart Card Reader

The SCM Microsystems SCR3311 is an external USB 1.1 smart card reader designed for secure authentication and transaction processing. It features a single slot supporting ISO 7816 Class A and AB cards with sliding contacts rated for 100,000 insertions. The device is fully PC/SC and EMV Level 1 compliant with CCID support.

Suited for single-card desktop authentication

This reader suits users needing a dedicated device for one smart card at a time on Windows, OS X or Linux platforms. It draws power directly from the USB bus and includes a dual-state green LED for status indication. Buyers requiring simultaneous multi-card access or internal installation should consider alternative form factors.

Handles standard smart card operations

The reader communicates at speeds up to 344,105 bps with a frequency up to 8 MHz, supporting T=0 and T=1 protocols. Memory card access is available through the SCM MCARD API. The upright white housing measures 95 x 64 x 85 mm and weighs 0.45 kg, allowing one-handed card insertion on a stable base.

商品問答

Do I need a free USB Type-A port on my computer for the SCR3311 reader?

Yes, the reader connects through a USB Type-A plug and draws all of its power from the bus, so a spare port is the only requirement.

Will the SCR3311 work through a USB 2.0 or 3.0 hub that I already use?

The device is a USB 1.1 full-speed peripheral; it will enumerate on any newer hub or port, but the link will run at the 12 Mbps rate of the original interface.

How can I confirm the reader is communicating with a smart card after I plug it in?

The single green LED on the front changes state when a card is inserted and the PC/SC driver establishes a session, giving a clear visual indication of activity.
