Manhattan Associates uses RF technology along with temporary or permanent RF tags.
Red Prairie's Yard Management solution also uses RF technology that checks trailers in and out at the guard shack.
"A load could be a priority shipment in that it needs a quick turnaround because it's either late or has out-of-stock inventory on it," explains Kozenski.
"Or it could be a live load, in which case the driver will stay with it until it's unloaded and ready to leave. When a trailer is ready to leave the yard, we check it out of the yard through security, capturing the driver's name, the license number, the number of the tractor, the seal number and whatever other security information the company needs to collect," he says.
Kozenski notes RFID is still an emerging market and companies commonly use RF and scanning for data entry. Red Prairie's Yard Management product uses RF technology and the company will soon launch its RFID version.
"Internal fleets could have permanent RFID tags on their equipment and, if not, we have temporary tags we put on and take off as trailers enter and leave the yard."
