iBR9000 is the newest in a family of iButton readers designed and manufactured by Videx. Made in the U.S.A., the small and lightweight unit is ideal for use in any checkpoint application where end-users need to know who was there, and when they were there. The miniaturized data collector measures 2-¾ inches in length, weighs less than 2 ounces, and easily fits on a key ring or in the user's pocket. The unit provides an audible tone and its LED light flashes when it reads an iButton successfully. Thanks to ample memory capacity, end-users can store at least 9,000 reads before the next download of data. The product is powered by a standard 3-volt lithium camera-style battery, good for up to a full year or 75,000 consecutive button reads.
