Wristwatch RFID tags promise much and so far fall short

As usual a company has started with what is arguably a good idea and expanded it so much that you're wondering why world peace isn't included in their promises. Ok maybe not
that much but still. The company in question is Winwatch, which has joined forces with Hitachi to put their (Hitachi's) RFID µ-chips in the glass face of expensive Swiss watches. This chip will contain a unique serial number so retailers and buyers can confirm that it is authentic. And because the antenna is so small, it can't be read from more than 1mm away, eliminating the possibility of someone sitting in a cafe waiting for a Rolex to come by. Good idea so far. The next suggestion is that this RFID
tag be used to fulfill all the promises made by RFID-boosters, such as ID, payment and customer loyalty cards. It seems a bit premature to foretell widespread adoption before they've even signed one company to use the tags. Reminds us of some old saying, something about counting chickens before they hatch.
