File this one under devices that make so much sense we thought they already existed. Someone finally invented what might be the most practical kiosk ever: an automated key duplicator.
The MinuteKey kiosk can duplicate nearly any key in a minute, requires a credit card (no cash), and the company claims that the machine's copies are more accurate than most hardware stores. One user recently found the 800-pound machine in the wild where the price for 1 key was $1.49, and 3 keys for $3. When choosing your key you can also pick a decorative key design, with the only significant limitation being that the machine will not duplicate car keys.
According to the website, you can find the kiosk in a number of Lowe's and selected Costco, Sears and Walmart stores. Sorry Mom-and-Pop stores, but it looks like the $2 billion key copying business has been officially disrupted. You can see the MinuteKey kiosk in action in the video below.
