Radio-Frequency Identification (RFID) is a wireless technology used to transfer data over short distances in order to identify and track objects. It is used in much the same way bar codes and magnetic strips have been used for years. While this technology is decades old, it is becoming more widely used in recent years due to the adoption of more complete standards and the lower cost and smaller size of the equipment involved.
There are many uses for RFID including; ID badges for access control, tracking of packages, baggage and goods, payment systems, such as toll and retail payments, and the timing of sporting events. RFID "chips" can also be implanted into animals and even humans to aid in identification. Many smartphones have the RFID capability as well (known as Near Field Communications, or NFC).
So ... why not an RFID geocache? No, this isn't the first time this has been done. Just the first around here. This should be an easy find and hopefully a quick stop. Once at the cache site, you will find instructions on how to open the container. Parking is available along the road.
