Trolley security

Back in the margins of trolley 53, I noticed the security fitting on one of the front wheels of a Sainsbury's trolley. See reference 1.

Then the other day, in the margins of trolley 61b, noticed at reference 2, I took another look. The security device and the company stamped on the casing seemed to have changed. We now had carttronix on the case, the people at reference 3, who look to be much more obviously in the trolley game than the last lot I noticed. The catch is that their solution does not seem to be quite the one that I see at Sainsbury's.

It comes with a high-vis wheel lock, never seen by me in all my visits to the place, which engages when you try to make off with the trolley. Perhaps also when you try to return one. But it is, I suppose, possible that Sainsbury's is the leading UK operator mentioned - with Epsom being on last year's stuff, with some other tier one store getting this year's stuff. Perhaps I will call in customer services and see if they know anything: a bit of a long shot, but then the girl answering the phone at Kiln Lane did know about the geothermal contraption in the car park. See reference 4.

For those interested in such matters, you can go to reference 3, click on a picture and see the thing in action. It certainly looks to work in the advertisement.
