gps tracking

my friend who is in the trucking business is thinking of investing on a gps tracking system to make monitoring easier for him. in the past months, he has been having problems with his drivers and have been encountering a lot of delays. he has been receiving a lot of complaints also from his clients of late delivery. with the gps system, he'll be able to trace where his trucks and drivers are. it is going to be a very expensive investment but will be worth it in the end. technology really makes a big difference in the world of business.
