USB Wedge, 21040145, Card Reader

The Mini Wedge Reader looks transparent to both the keyboard and the PC until a card is read. Power is supplied via the keyboard port from the PC. When a card is read, the Reader disables the keyboard and sends card data using the same scan codes used by the keyboard. The PC cannot distinguish between data from the keyboard and data from the Reader. In addition to reading the standard credit card and driver license formats, these readers will read custom formats such as 7-bit encoding on all 3 tracks
