Competition Watch

You're on the doorstep at home, you check your pockets, your jacket, bags... no sign of your house keys anywhere, and no-one at home to let you in. Sound familiar? Well, we're going to make your life a whole lot easier with the revolutionary finger print lock from gadgetstorm.com. Install the lock on an exterior door, and an optical sensor can be programmed to recognise your finger print, so you just touch the sensor pad and hey presto you're in. The door can also be operated by a four digit PIN number if you need to let others in.
