The TMSR33U USB Magnetic Stripe Card Reader is a compact, decoded mag-stripe reader designed for seamless integration with modern systems via USB. Measuring approximately 96.5 mm × 30.5 mm × 32.2 mm, it is among the smallest in its class. The device supports reading of standard magnetic stripe cards—Tracks 1, 2, 3, and JIS-II—compliant with ISO and JIS standards. It uses the F2F (two-frequency coherent phase) swipe method and can handle swipe speeds between 5 to 60 inches per second. The reader operates on a +5 V DC power supply (±10 %) with current draw less than 100 mA. Its magnetic head is rated for at least 300,000 swipes, with optional versions supporting up to 1,000,000 swipes.
