It's an Android app I use to update our Database. The search facility doesn't differ a whole lot from TfIs Driver Check app, it just gives the plate owner (subject to certain assumptions) and an Industry ID that doesn't mean a whole lot, just an ID number allocated by NTA when a vehicle is associated with a driver. The advantage to me in using it is that it automatically updates our system where required. I probably shouldn't post pictures of it TBH, I was just too lazy to open the TfI one. Anywaysanall it's available to members* on request.
Edit: *members who are known to be taxi drivers, either by me or vouched by another member/admin, him/herself being known to me as such!
