Most pins?

RFID=Proximity readers and cards.

Not always. They can also use the Wiegand electrical and protocol interface.

Once again, RFID is just the technology that allows it to take place, just as TCP/IP allows information to flow on the internet.

Sorry for the double post but here's a proximity reader that doesn't employ RFID technology, instead it uses Wiegand.

I should have been specific in my original post. I was referring to actual stacks of pins the most I've seen being 12. I couldn't say how many actual pins are in there.

Out of curiosity, what does this use to pick up the signal from cards and such.

Radio Frequencies.

Not the same band or standards as RFID cards though. I don't remember the exact ISO number but they aren't related, just as cell phones (who use radio frequencies) aren't identified as RFID devices.

is it really possible to use more than one master wafer in the same chamber effectively? I keep hearing people say this and in 2 years as a locksmith i've never seen it done and don't see why you would want to.

Pick up a copy of Bill Phillips "The complete book of locks and locksmithing". It explains grand master and great grand master keying. It's very interesting to me now that I have read it over a dozen times and finally got what the heck he was talking about. That section of the book is definately not for for beginners. I first thought the book was useless, I later realized that I bought the book to early and just did not understand.

i've done 4 level master key system before, but still haven't had to use more than one master wafer per chamber.

presumably, the wiegand wires are energized by the field and become antenna sending out a signal. Wiegand is the interuption in a copper wire where that wire is bent or kinked. apparently the electrons skid into the ditch and this can be read.

Yeah, that's pretty much how it works in it's access control form. I've seen a few products that implement RFID within Wiegand.
