Going Underground

The latest application that we're involved in is a deployment of RFID on the London Underground. They are using UHF RFD tags to keep track of which individual escalator steps need maintenance (no, I hadn't realised that they needed to worry about individual steps either!).

As part of the project they are tagging 30,000 steps and using RFID readers mounted beside moving escalators so that they get an instant read out of which steps need exchanging without stopping the escalator.

It's a MUCH easier way of doing it than peering in the dark and greasy underneath of an escalator looking for labels on the steps.
