However, one geriatric patient in New Zealand has established something of a record with the first one man RFID warning system.
One of client had limited mobility and needed a motorised wheelchair – the problem is his penchant for driving straight through the gates of his private nursing home and into the busy traffic of a main road.
To solve the problem, a Protrac iD tag fitted to his wheelchair locks the brakes and turns off the motor as soon as his signal is picked up by a receiver half way down the drive.
An expensive solution for just one patient you might think? Not really, since the patient’s life is at risk and the nursing home would be legally liable if any harm came to him.
