TrackingTheWorld has come up with a potential solution to the problem of letters that go missing in action. Letter Logger is a quarter-inch-thick device that fits into a standard number 10 business envelope and allows the US Postal Service to track its progress throughout the system alongside Google Earth. Here's how it works.


Letter Logger consists of a powerful microprocessor developed by Texas Instruments, and a low-power consumption uBlox ANTARIS 4 GPS module, and is powered by a slim 1100mAh battery. It can be deployed in two different ways. Users can choose to receive reports every two, five or ten minutes (which would, I think, drive you nuts) if Letter Logger is in Constant mode, or they can go for Tilt mode, which notifies you only when the envelope is tilted. Constant mode gives you 20 hours' battery life, while Tilt mode will keep tabs for two weeks.


The service starts up on January 2 next year and it won't be available to the general public. It's a shame the British Government's Customs and Revenue department didn't have access to this when the CD-Rs containing 25 million people's bank details got lost in transit earlier this month.
