	Hi, I tried the "General" without any result I hope in this advanced technology domain I could have more luck. I need your help: for a project I need RF id for a limited space. The tag and the antenna should be less/equal 10 mm(13/32") in diameter, if less then better. The circuit should be as small as possible as well. The identification is thought for inserts in a portable tool which asks for a reduced current requirement and a sleeping mode with even less. Did any body met such devices? I tried via Google (as I recommend to others to do) but I did not find any totally satisfactory combination. In position for identification the distance between tag and antenna is 1 to 2 mm (0.04"...0.08") only. I shall be very thankful for any indication even if the comonents do not come all of them from same supplier Nickname

	Hi nick name, Have you thought about using the medical implantable RFID tags. They are about the size of two grains of rice, including the antenna and specifically designed to be implanted just under the skin. Originally they were designed and have successfully been used for over a decade to track pets but there is a version that has been approved for use in humans. They don't hold any information just a unique 16 digit number that can be used to reference records. They are specifically designed for subcutaneous implantation and meant for tracking patients but the technology may be useful for your application. VeriChip manufacture them and you can get a starter kit that has everything you need to test out if they are suitable for you application. I have been interested in using the technology myself in a security application so I would be interested in what you learn.

	Have a look at TEC-TUS.COM. They have a lot of tags and readers. One of their glass tags is 13.3mm long with a diameter of 3.25mm and is used for pet identification. Regards Uwe __________________ The sum of intelligence on earth is a constant. And the population grows and grows and .....
