Ah! Geek: Kids use fudge to copy fingerprints.

Many companies to work open is used by a fingerprint machine, in order to prevent employees to punch in, late to leave early and so on.

Recently, a high school in Kangaroo State (Australia) also installed this kind of thing, intended to regulate the children's behavior during lunch (it seems to be unified lunch). The result is outsmart, however persuasive. A few days after the fingerprint punch was installed, the kids came up with a trick, using the Bear candy to copy their fingerprints and then open them. Not only that, some fingerprint scanner also has a body charge check, this thought this will not be false, that the strong bear candy and the body finger skin has the same capacitance, so check out or the same. Those who need to punch in at work now understand. So later the company will still carry the bear jelly.
