SENDUM WIRELESS builds wireless location products that improve Supply Chain Security and offer new levels of customer service. Sendum's devices will operate in environments where traditional GPS will not work. Sendum’s products are small (pager sized), rugged, with a long battery life (21 days) allowing them to be easily hidden in cargo and vehicles. A user sits down at any computer connected to the internet, enters in the device number and its location is shown on MapPoint. It’s that easy!
