It seems there is no end to the uses of black-box technology. Norwich Union (NU) in association with IBM and Orange this year unveiled Pay-As-You-Drive based on a little black box that sends data in real time on where, how and when you drive.

NU argues this gives them a better understanding of the risks you are taking and thus a fairer rate. Now those NU boffins are considering using the technology in rating household policies. Apparently, little black boxes could be installed in homes, allowing remote activation of locks and alarms that would prove to NU that policyholders deployed their security measures.

Whatever next? Microchips in suitcases to prove tourists are heading for Majorca and not Iraq?
