SparkFun: ID-12
SparkFun: ID-20
They are working very well with my N+ setup, however I am very disappointed with the range vs. price. They hardly achieve 40% of their range specifications even under ideal circumstances.
I found this unit the other day:
Parallax: Serial RFID Card Reader
Does anyone have any experience with it? What sorts of real-world range could I expect with it? Is there another, similar device out there I should consider??
Thanks in advance!

I have the Parallax and the range is about contact to one inch. If I house it in an enclosure it usually requires the card to touch the enclosure to get a reading. The 125khz devices don't have that great of range.
Is there an alternative technology I should perhaps be considering?

I found the range of the ID-20 / credit card sized tag was OK. May be down to lower expectations on my part though.
About the ID-20, did you have any trouble with it in a breadboard? I have not soldered it to the breakout board yet because it seems that there would be no room to connect to the breadboard's pins underneath.

Here's what I found:
The ID-20 ignores the Paxton key fob tag and my work CC tag.
The door at work ignores the CC tags that came with the ID-20 but sees the tags for my friend's house.
I assumed that it was an EM4001 / EM4100 incompatability issue. Maybe that's not it.
