Some of you may already be familiar with the RFID (radio frequency identification) technology in place. It can help you to:

Regain a lost family pet who gets out of a gate, on that balmy summer evening.

Track the real times of Olympic athletes.

Find that golf ball you lost on the green. (What did we learn? Never put angry!)

Assist your doctor in being sure he got everything out of your body before he stitched you back up after surgery.

Make smart homes for seniors a reality.

Well, thanks to one company, RFID's are growing in range.

GAO Tek had developed an RFID with an impressively long read-range of up to eight meters. The device can be easily attached to any metal surface either mechanically or by using industrial adhesives. Of course, as you probably guessed by that statement, you are more likely to find this device on Fido's tag then in his body. After all, you need to be safe when you are inserting things into any living being. There are also several other version of the tag in development which can be attached to non-metal surfaces. All of them were developed for commercial applications and not human use. Those models are still in the lab versions.
