This is an interesting blog on the subject of mobile applications in the rail industry.
MobileDataforce is now working on a proposal to use RFID to inspect and inventory cargo in rail cars. This is quite interesting. The user walks up to a rail car and uses an RFID reader on a ruggedized PDA to see what is in it. This solution uses our PointSync software to integrate with the RFID reader, query a database on the handheld computer, and show information on the cargo in the car.
