Mag-Tek Inc. has unveiled a card-reading device that does not require an external power supply.

Designed for use at gas pumps and self-service kiosks and in the gaming industry, the Port-Powered Insert Card Reader fulfills its low power requirement from an RS-232 serial port connection.

With dual heads, it reads standard single- or dual-track magnetic stripe cards in either of two orientations for ease of use. Mag-Tek was the pioneer of magnetic-stripe reading technology more than 25 years ago.
