Would be great if you had some way like RFID to scan for those tags, so that when you lose your phone in your house, you can quickly locate it :)

- eli 12y agoI think the RFID on most phones (that even have it) is very short range. http://www.thetileapp.com/ http://www.thetileapp.com/ uses Bluetooth.
- lucb1e 12y agoDoes RFID work over 10 meters? I thought the issue was that the reader needs to power the tag. If the tag is self-powered, that means it runs out of batteries and that you're carrying something that constantly sends signals everywhere you go.
- sbierwagen 12y agoDirectional antennas and high-power radios can increase the range a lot. Access-control RFID readers have low-power radios for obvious reasons: any time someone with the right card walked by, the door would unlock itself.
