Technology similar to RFID?

[cjoweb33]

I am looking to make a project where someone wearing something similar to an active RFID tag wristband could walk into a room and their preset lighting style would be turned on.

Is there anything that can be used with Arduino besides UHF RFID that could do something like this? I know 433 MHz could get close, but I don’t want to have two arduinos.

Basically I want to be able to sense a unique ID from a tag of some kind with a range of a couple meters or so.

Thanks for your help!

Take a look at the PRT100 Long Range Contactless Induce Reader, that may just do it for you.

Instead of radio, the wristband could function like an IR remote control.

Have an IR LED emit a series of pulses, unique to each person. The Arduino IRremote library can be used to encode and decode IDs.
