Two magnetic heads allow a card to be read with one swipe, whichever way the magnetic stripe is facing. The bidirectional configuration of the reader enables cards to be swiped backward or forward at a speed of up to 60" per second.The built-in USB cable measures 6' long and can be plugged into the USB 2.0 port of a computer or another host system (sold separately) to transmit card data and power the magnetic card reader. USB keyboard emulation enables the reader to transmit data to host systems and applications designed to receive keyboard input. An LED indicator turns red to alert the user of a decoding error.
