With Bold, your smartphone is your key. Enter and leave your house with your phone in your pocket; Bold will (auto) unlock and lock your door as you come and go. Having guests over?

You are the digital key master: give your spouse permanent access, let the plumber in Monday morning and the cleaning lady every Friday afternoon. You decide! With the highest level of security (think of digital banking-security), your house is safer than ever before.
