The HID Model 644 Pass-Through Card Reader provides the simplest card-reading interaction: one smooth pass through the slot reads the card. The reader mounts on a standard electrical wall box or directly on a door mullion, offering installation flexibility. A bi-color LED winks to confirm a read, then changes color when the door unlocks — no guesswork for users. Available in black or white. The field-adjustable read head supports track 1 or track 2 reads. Wiegand or Clock-and-Data interface. Reads security badges, time and attendance badges, and parking cards. Dimensions: 6.0" x 1.75" x 1.49".
