sweet, getting up there! But I don't think it will work if the card is in your pocket or wallet. I would have to call them about that.

Ok I give up. Here are the last few links that I have found.

Now all you have to do is figure out how to mod it to do the reverse. Normally it says the alarm will sound when you walk away from the transmitter's 15 foot range.

You want it to 'sound' when you come within the 15 foot range. Hmm, actually doesn't seem that complicated - nice find!

• Fellowes Proximity Alarm
• RF wireless
• The receiver measures 2 1/2 in (H) X 1 3/4 in (L) X 3/16 (W) and the transmitter measures 1 3/4 in (H) X 1 1/2 in (L) X 3/16 (W).
• Both units use a long life CR2032 battery which is included.
