The Bluetooth LED Name Badge allows you to program up to eight different messages / graphics on an LED matrix. Each badge is a single color. It utilizes a micro USB cable to both charge and connect to the computer for more advanced programming. While in the field, you can use the LED Badge app to re-program the tag on the fly with your current message. The resolution of the matrix in pixels is 44 × 11. The badge can attach to a garment via either a pin or a magnet (included). Please refer to this page for programming instructions.
