Default What was this for?

Hello
I was at my grandad's today, and we went for a walk in the garden, and on the wall next to a door, there was this (pictured below), and I would like to know what it is, so, if anyone could help me, that would be great!

I'm wondering if it could be some sort of hookup for a deaf-aid or an audio-description?

I remember a few decades back in some stately-homes/gardens etc. you could hire a headset and at various significant places there were sockets you could plug the headset in and hear an audio-description of that particular location.

Or maybe it's a slot for some kind of pass-key that allows specified people to open the door?

The icon seems to suggest it's for some sort of electronic key, that would be touched against the "socket" in the middle to release the lock.

So there's probably something very interesting behind that door, and has been for some time!

Judging by the "key" symbol above, it was probably an access key that was put in at the same time the RFID reader was put in about 10 years ago?

There really isn't anything interesting behind that door because it just leads inside the flat complex

So what does the RFID system do, open a powered door? Release a magnetic lock?

I reckon superdirto is probably right. It means a security guard touches the pad, and it records that he visited there (as opposed to snoozing somewhere). I couldn't find one just the same. Many of them use the Dallas transponder discs.

My vote is with post #5 a security check point, put in so that as the guard does his round he has to touch in at various points round a large site rather than having a sleep in their hut!

I'm going to go out on a limb and say that they are for the warden in the complex to open the said door and gain access into the complex from the stairs, although this is the only example of the "device" in the entire building
