Super high power NFC Reader

[johnyma22]

Anyone know of any super high power NFC Reader? Obviously we have the PN532 which is a decent reader but I'm thinking something that will work at extraordinarily long distances (5cm+) and in return uses a lot of power/energy..

Any thoughts?

A parking garage style reader would do the job.
Something along the lines of this.

MrStein research on the NFC antenna and Arduino would be useful...
