Cattle farmers are now using Wap devices to keep track of their cows.
Edward McKenzie, who looks after 800 cattle at his north Scotland farm, is pioneering the system developed by Braidgrove.com, which allows animal records to be updated on a central database, no matter how remote the location.
"Since the BSE crisis, farmers have had to record every movement, birth and death within the herd," said McKenzie. "Wap is far more efficient than all the pieces of paper I carried around previously. Farmers are under real pressure these days and this saves invaluable time."
