90mm Rail, OEM Magstripe Reader
(IDT3304 Series)
90mm Rail Specifications

The 90mm rail is a MagStripe reader for OEM applications. It reads up to three tracks of data with a single swipe in either direction. Its 90mm length slot and mounting options make it a perfect fit for reading magnetic stripes in any OEM application. It has reliable MagStripe reading on damaged or bowed cards. The rugged ABS plastic chassis with molded-in stainless steel card wear plate exceeds 1,000,000 card swipes. The reader is available in custom configurations including intelligent interfaces, and custom cable/connector options.
