Charles Walton, the Father of RFID
Today, I will not tell you about the benefits of RFID tags to Wal-Mart supply-chain or the potential dangers to our privacies brought about by these tags. No, we'll look at the origins of the RFID technology, which is surprisingly more than thirty years old.

In a very interesting article, the San Jose Mercury News tells us about Charles Walton, the man behind the radio frequency identification technology (RFID). Since his first patent about it in 1973, Walton, now 83 years old, collected about $3 million from royalties coming from his patents. Unfortunately for him, his latest patent about RFID expired in the mid-1990s. So he will not make any money from the billions of RFID tags that will appear in the years to come. But he continues to invent and his latest patent about a proximity card with incorporated PIN code protection was granted in June 2004. Maybe he'll be luckier with this one.

This overview contains some excerpts of the original article. It also contains tips to search for Walton's patents and an image of the front page of his first patent.
