USB MagStripe Reader for POS Systems

The MagTek Dynamag 21073075 reads magnetic-stripe cards on tracks 1, 2 and 3 at speeds from 4 to 60 ips. It connects through a standard USB port and draws up to 110 mA in normal operation. The unit measures 1.23 by 1.28 by 3.94 inches and weighs 0.28 lb, making it a compact choice for retail counters.

Check USB Port and Software Compatibility

Verify that the host system provides a USB 5 V supply and supports either USB HID or USB Keyboard emulation modes. The reader is powered entirely from the bus, so no external adapter is required. Confirm that your point-of-sale application can accept raw track data, as the device does not perform on-board encryption.

Compact Build with Simple Status LED

A red, green and amber LED gives immediate visual feedback on read status without needing software prompts. The sturdy black housing operates from -30 °C to 70 °C and tolerates 10 to 90 % non-condensing humidity. Buyers who need end-to-end encryption or contactless NFC reading should look at other models.

Questions about this item

Does the 21073075 Dynamag come with a USB cable or must I buy one separately?

The reader includes a USB cable so no extra cable purchase is needed.

The specs list two USB interfaces — HID and Keyboard emulation — which one should I choose for a Windows POS?

Both interfaces work on Windows; HID is standard for most POS software while Keyboard emulation lets the reader act like a keyboard for simple text entry.

What does the 4 to 60 ips swipe speed mean when I am serving customers at the counter?

It means the reader reliably captures data from slow hand swipes up to fast card-present transactions without requiring a precise speed.
