Caution- On Topic: Anyone got any ideas for RFID for sports?

what read-range do you need? how many readers?

passive tags can take upto 300ms to charge up before responding, active tags will likely blow your budget.

I imagine they would be attached to peoples ankles, jogging pace would be a reasonable speed, maybe they could walk over a target. Need about

100 of them. Probably two readers, start and finish, and results somehow into laptop.

For counting people walking/running past a point, possible. For actual

*timing*, it almost certainly won't work. Tolerances in range, response time, peoples body position etc would make in impractical.

Exactly what are you trying to achieve?

Timing people in mutisport events. Walking through timing points is ok.

Tried this bloke:

They've got a neat system, all Aussie developed & manufactured.

I know Andrew well, having competed against him many times in the past. It's too expensive to hire his system, I'm in a country town and he's in the city, you essentially hire him to set up his equipment. I'm after a system that a small club could buy and set up. Technology has changed a lot since Andrew started developing his system, maybe I could use cattle RFID tags. (Just hold still mate while I poke this through your ear!)

OK,

Have you seen the 900MHz RFID stuff.

Readers up to 4 watts power, read ranges in excess of a few metres

600tags a sec read speed Anti Collision

Adilam has the 900MHz readers and tags, but you will have to create your own system.

I like the look of that. I just sent them a message to see how I go about getting hold of a evaluation kit.
