WHAT IS THIS?
A house key app under development for smartphones lets users wave their
phones at doors to unlock them. The app, called ShareKey, also will
allow its owners to electronically share keys with a houseguest, a family/friend, or anyone else they like -- and
to attach certain limits to that access. A company could use the system
to control employee and guest access to a building from anywhere in the
world, says ShareKey's creators at the Fraunhofer Institute for Secure
Information Technology in Germany.
