How does it lock? The first component of the iPad lock is a hard, clear plastic case you can leave on for everyday protection. And since the iPad has no security slot, the case has one built in. That way you can lock the security cable to the case, and loop the cable's other end around a fixed object (like a table). Once the case and cable are locked together, thieves can't detach the case without damaging the iPad. Likewise, the strong steel cable will discourage any thief. Weighing less than one pound, the cable is extremely sleek and its lock-head has the smallest diameter of any computer lock in the world. This makes the iPad lock flexible and light, not to mention stylish, so you can easily pack it in your bag and take it with you wherever you go!
