Cheers Boncuk for the info.

I have put in another clearer image of the item in question.

You say it could be an ibutton !! I can see your thoughts on this but on close inspection there are no markings on the surface of the device and I feel as you describe an Ibutton then this device does not match that description.

The device is approx 1.25mm square the device is glued in place so without removing it I can't be sure of it's thickness but I would guess at 1mm or so.

I googled on the DS1990A (ibutton) and it does not resemble this as I see it. none the less the Ibutton looks a great product.

I will still asume that it's an RFID chip until it's shown I'm barking up the wrong tree!!

Cheers Mark

Hi all
After further research I am now also convinced that the device as sated a RFID chip.

I will require a scanner/writer to make further "passive tags" These can be purchased quite cheaply.

obviously there are legality issues in reproducing clones of the original fob and not knowing these Legalities I will leave well alone until I seek further info from the Local Council

Thanks for all your help.

Hi Mark,

I'm convinced that there are legality issues. If you could just insert any chip house security would be sacrificed.

If somebody looses his fob he will receive a registered one which is also contained in the comparison list of the access control computer.

Cloning such a device you might be faced with the charge of burglary (at least attempted burglary).

So it would be wise to get as much information as possible from the local council about those fobs and if possible, the system. (I doubt you'll receive any info about the system)

If the spare fobs are prepared at your local council there won't be any other way than paying the astronomic price for them - or take better care not losing them.

The I-Button system appears to me far cheaper than this RFID thing. There are special fob holders on the market just made to make the fob bigger to avoid losses.

You also might get familiar with the idea that local councils tend to purchase the most expensive and most useless stuff. (At least they do in Germany, so why not in other countries)

I have yet to speak to the Center Warden about the issue and I am sure that the council have pre-purchased a quantity of already programmed tags what quantity I don't know.

What is quite concerning in the way of security is many of the fobs are purchased by the residents for none relatives such as none contractual cleaners , helpers and the odd job man.This leaves the center quite venerable.

I'm sure these fobs could be as little as £5 for me to produce but I'm now thinking this will also have a negative effect on security , the cheaper they are the more they hand out

I'm thinking more of chanaging some the fobs to suit the persons needs say a tag in a wrist watch or maybe a sticker tag on a Mobility Scooter just to make it a little easier for some of the residants.With this in mind I can approch the council. and see what they say

Not something I've thought too deeply about just yet as first off I had to find out what tech I was dealing with.

BTW. Yep the council around here in south yorkshire (UK). do seem to spend lots of cash on the wrong things and very little on the right things but that's another toppic and probs another forum!!!!

Thanks to all Mark
