RFID and Sensor Support?

[randomblink]

Alright, so I'm looking into various sensors and stuff, getting a shopping / price list together.
Something that dawned on me was RFID? Has ANYONE gotten RFID to do ANYTHING in a LinuxMCE environment yet?
I can't seem to find anything, anywhere on it.

i'm playing with an active token from hong kong. Basically you send presence detected/lost events.

I'm wondering how well this concept would fly.

On the one hand, you could setup follow me quite easily, and nicely.
On the other hand, I want it to unlock my door when I get close to it, and lock when I go away but there's too many 'what ifs' in that scenario for my taste.
But I like the idea of RFID'ing my cats collar and unlocking the pet door for her, that would be kinda cool in that geeky way I love.

ah, thought you want to use it for presence detection/follow me. I'd better not use RFID for door locks. Not without expensive active crypto tokens.

best regards,

I don't follow you. I thought each tag had a unique ID. Are you saying for security applications, instead of just presence, not any RFID would do. Where's the problem - that they're easy to copy, or that they're not unique?

I also want to use it for a pet door, but in my case it's not just because it's geeky and cool. The door is for a big dog, and it's large enough for a man to get through. RFID on the dog's collar was the only idea I came up with.
