The first component of the patent-pending iPad 2 Lock / iPad 3 Lock / New iPad 4 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.
