If you’re filthy rich, you probably have wads of cash lying around in your home. If you’re having trouble counting those dollar bills the normal way, you could hope really hard for this Counting Ring concept. Instead of having to purchase a big bulky money counting machine, this device can be worn on your finger just like a normal ring, featuring an LED display, power switch, sheet-separating veins, battery slot and infrared scanning. So all you have to do is flip through the notes with your thumb and the device will count all the notes for you. It’s a really handy idea, and hopefully we have that much money lying around the house when this device finally becomes a reality.
